Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.

As described above, in the related art, it is necessary to divide a plurality of network devices into different virtual local area networks (Virtual Local Area Network, VLANs) in order to facilitate management of the network devices. For example, an enterprise includes 20 hosts, 2 hosts for financial work, 3 hosts for administrative work, and 15 hosts for research and development work. The 20 hosts can be respectively divided into different virtual local area networks according to the different operation types to perform networking, such as VLAN1, VLAN2 and VLAN3. However, if the network topology formed by the network devices is successfully networked according to the networking scheme, in the related art, whether the networking is successful can be determined by manually inquiring the network configuration information on the network devices, so that the detection efficiency is low. In consideration of that network access can be realized between network devices in the same virtual local area network after networking is completed, the network devices in the same virtual local area network as the network devices can be considered to initiate access, and the state of the network devices, such as on-line or off-line, can be determined according to the access result to determine whether the network devices are successfully networked.

Specific implementations of the above concepts are described below.

Referring to fig. 1, an embodiment of the present invention provides a network topology state detection method, which includes:

step 100, determining an entity network topology to be detected; the physical network topology includes a plurality of network devices;

102, acquiring networking information corresponding to the plurality of network devices respectively;

104, creating virtual detection equipment belonging to the same virtual local area network as each network equipment according to networking information respectively corresponding to the plurality of network equipment, and initiating access to the plurality of network equipment by utilizing the virtual detection equipment so as to determine the state of each network equipment according to the access result;

and step 106, determining whether the entity network topology is successful in networking according to the state of each network device.

In the embodiment of the invention, because the entity network topology can access among the devices belonging to the same virtual local area network after the networking is completed, the virtual detection device and each network device belong to the same virtual local area network by creating the virtual detection device, thereby the virtual detection device can be utilized to initiate access to the network devices which belong to the same virtual local area network, the state of each network device can be determined according to the access result, and further whether the entity network topology is successful in networking can be determined. Therefore, the scheme can automatically complete detection without artificial participation, so that the detection efficiency can be improved.

The manner in which the individual steps shown in fig. 1 are performed is described below.

First, for step 100, determining an entity network topology to be detected; the physical network topology includes a plurality of network devices.

For convenience in describing the present embodiment, two concepts are introduced here:

physical network topology: and the network topology is formed by physically connecting the plurality of network devices after networking. In the physical network topology, the connection relationship between the plurality of network devices is called an entity connection relationship.

Simulating network topology: in the drawing software for drawing the topological graph, the network devices are added to the topological editing page of the drawing software in a corresponding graph mode, and then the graphs of the network devices are connected by using a connecting wire to form the network topology. In the analog network topology, the connection relationship between the plurality of network devices is called an analog connection relationship.

In the embodiment of the invention, after the entity network topology is networked according to the set networking scheme, in order to determine whether the entity network topology is successful in networking, the state of each network device in the entity network topology needs to be detected.

Where a network device is a physical entity connected to a network, such as a computer, hub, router, switch, firewall, bridge, gateway, printer, camera, etc.

Networking is a network building technology that can partition multiple network devices into different VLANs. For example, the set networking scheme is to divide 10 hosts into 3 VLANs, wherein hosts 1 to 3 are divided into VLAN1, hosts 4 to 6 are divided into VLAN2, and hosts 7 to 10 are divided into VLAN 3. The hosts are connected to the switch, and may be one switch or multiple switches. In VLAN classification, this is required to be achieved by at least one switch connecting the hosts.

In one embodiment of the present invention, in order to implement fast networking and manage the physical network topology after networking, before this step 100, please refer to fig. 2, the physical network topology may be networked according to a set networking scheme in the following manner, which specifically includes:

step 200, determining networking schemes required to be realized by the plurality of network devices; at least one switch is included in the plurality of network devices.

Step 202, obtaining a simulated network topology corresponding to the networking scheme. The simulated network topology includes simulated connection relationships between the plurality of network devices and networking information of each network device.

In this step 202, when obtaining the simulated network topology corresponding to the networking scheme, the following two cases are included:

first case: there is no physical network topology at this time.

Second case: at this point there is already a physical network topology.

The requirements for the simulated network topology are different when corresponding to the different situations.

In the first case, no physical network topology exists, which indicates that the network device has not been physically connected. At this time, a connection mode that the connection relation is simpler for the plurality of network devices according to the networking scheme so as to facilitate the physical connection can be obtained, and a simulated connection relation in the simulated network topology is formed. After obtaining the simulated connection relationship in the simulated network topology, the plurality of physical devices need to be physically connected according to the simulated connection relationship to form the physical network topology.

In the second case, since the physical network topology already exists at this time, the physical network topology may also include two cases: in the case A, the entity network topology has performed networking on the network equipment, but the networking scheme is different from the networking scheme required to be realized at this time, namely the networking scheme needs to be changed; and in the case B, the entity network topology does not network the network equipment. However, in the case a or the case B, the physical connection relationship of the physical network topology is not changed, and when networking or replacing networking is performed, a switch is required to complete a networking scheme to be implemented. Therefore, in the second case, the simulated network topology needs to connect the plurality of network devices on the topology editing page according to the entity connection relationship in the entity network topology, so as to form the simulated connection relationship in the simulated network topology.

In summary, whether corresponding to the first case or the second case, it is necessary to ensure that the analog connection relationship in the analog network topology is the same as the entity connection relationship in the entity network topology.

In one embodiment of the present invention, the method for obtaining the simulated network topology corresponding to the networking scheme includes at least two modes:

the first way is: the simulated network topology is newly drawn.

The second way is: and obtaining the simulated network topology by using the stored template.

The following description will be made for the above two modes, respectively.

This step 202 uses the first approach to obtain a simulated network topology.

Referring to fig. 3, this step may include:

and 300, obtaining device packages corresponding to the plurality of network devices respectively on a pre-created topology editing page, and connecting the device packages to obtain the simulated connection relation between the network devices.

In one embodiment of the present invention, the mapping software may provide a topology editing function, and in response to an operation instruction input by a user, the mapping software may obtain a plurality of device packages on a topology editing page, and connect the device packages to obtain a simulated connection relationship between a plurality of network devices.

Wherein the device package is used to characterize the feature set of the corresponding network device. The device package may include graphic elements and text elements, and may also include interface elements.

The graphic elements are graphics used for representing corresponding network equipment, different types of network equipment can use different graphic elements, and a user can determine the type of the equipment package corresponding to the network equipment according to the graphic elements of the equipment package displayed on the topology editing page. For example, the type of network device is a desktop host, a notebook, a router, a switch, a firewall, a camera, etc. The created graphic elements may be stored in a graphic library.

The interface element is used to characterize each interface included on the network device, for example, a control interface, an optical interface, a USB interface, a Type-C interface, a universal asynchronous receiver Transmitter (Universal Asynchronous Receiver/Transmitter, UART) interface, a high-definition multimedia interface (High Definition Multimedia Interface, HDMI), a serial peripheral interface (Serial Peripheral Interface, SPI), and the like. In this embodiment, the interface element may be edited, for example, add delete or change interfaces. The created interface elements may be stored in an interface library.

The text element is used for recording encapsulation information of the network device, and the encapsulation information may include: hardware information and software information. The hardware information may include: device type, device identification, interface type, interface identification, device itself parameter information (such as processor model, frequency, hard disk capacity, memory size, etc.), operating system information, etc., the software may include: IP address, MAC address, vendor information, vendor ID, network device login information, etc. All text description information of the network equipment corresponding to the equipment package can be stored into package information through editing text elements, the package information is a part of the equipment package, and the package information can be displayed or hidden on a topology editing page according to different configurations. For example, when the package information is not checked or edited, the package information is in a hidden state, and when the package information needs to be checked or edited, the package information can be displayed. The display modes can comprise: in the form of a display window or by copying the encapsulated information to other video display units for display, etc.

The device package may be a package for one network device, or may be a package for a connection relationship between a plurality of network devices.

The device packages may be pre-generated and stored in a package library. The encapsulation library can perform operations such as import, export, selection, editing, calling, deletion and the like through the data interface.

In the embodiment of the invention, the graphic elements, the interface elements and the text elements of the network equipment are packaged together in an equipment packaging mode, so that the information included in the equipment packaging is more abundant and comprehensive, and when the simulated connection relation among a plurality of network equipment is drawn on a topology editing page, the graphic elements, the interface elements and the text elements in the equipment packaging can be rapidly edited, and the editing speed of the network topology is improved.

The method for obtaining the device packages corresponding to the plurality of network devices on the topology editing page in the step at least comprises the following three modes: 1. importing from a packaging library; 2. editing or creating on a topology editing page; 3. and copying and pasting the device package obtained on the topology editing page.

The device package can be deleted, moved, rotated and the like on the topology editing page. The operations such as movement and rotation may be performed in a two-dimensional coordinate system on the topology editing page.

In this step 300, the device packages are connected, specifically: connection elements may be used to effect connection of the respective device packages. The connection element may be a straight line, a curved line, a straight line with an arrow, a curved line with an arrow, etc., and may be used to characterize different types of links when the connection element corresponds to different types.

In one embodiment of the invention, when the device packages are connected by using the connection element, the corresponding relation between the device packages and the connection element can be stored, so that the analog connection relation between the network devices can be conveniently identified later. The detection script may be deployed in the device package in advance, and is configured to detect whether a connection element is connected to the device package, and when detecting that the device package has a connection element connected to the device package, obtain identification information of the connection element, determine a target element for the device package to establish connection with the connection element, and store a correspondence between the identification information of the target element and the identification information of the connection element.

When the device package does not include an interface element, the target element is a graphic element of the device package. For example, if the identification information of the graphic element is S01 and the identification information of the connection element is L001, the correspondence relationship of S01-L001 is stored.

When the device package includes interface elements, the target element is one of the interface elements of the device package. For example, the device package includes two interface elements, the identification information of the two interface elements is S01001 and S01002, the identification information of the connection element is L001, and the target element for establishing connection with the connection element is interface element S01001, so that the corresponding relationship of S01001-L001 is stored.

When stored, the correspondence relationship may be stored in package information of the device package.

Step 302, according to the information of the virtual local area network to which each network device is respectively divided in the networking scheme, configuring networking information for each device package on the topology editing page.

In this step 302, the configuration method of the networking information for each device package may at least include the following two modes:

and (3) manually configuring networking information on the equipment package in the mode A.

And B, automatically encapsulating and configuring networking information for the equipment.

Taking the example of the plurality of network devices comprising a switch and 10 hosts, the 10 hosts are connected to the switch. The information of the VLAN may be VLAN numbers, for example, dividing the 10 hosts into VLAN1, VLAN2 and VLAN3, respectively.

Then in mode a, the device package configuration networking information may be implemented by editing the text elements of the device package. The networking information may include, among other things, VLAN numbers, IP addresses assigned thereto, etc.

Then in mode B, this step may specifically include: creating a boundary frame of a corresponding virtual local area network on the topology editing page; and when the target equipment package is detected to be positioned in the boundary box, configuring networking information for the target equipment package according to the information of the virtual local area network corresponding to the boundary box.

The bounding box created may be a closed box, which may be configured to correspond to a virtual local area network. For example, the bounding box is configured to correspond to VLAN1, and when it is detected that a target device package is moved into the bounding box, text elements of the target device package may be automatically edited according to the information VLAN1 of the virtual local area network corresponding to the bounding box, so as to implement configuration networking information for the target device package.

By utilizing the mode B, the equipment packages of the network equipment belonging to the same VLAN can be quickly moved into the boundary box corresponding to the VLAN, and the equipment packages of the network equipment belonging to the same VLAN are automatically configured with networking information, so that the networking scheme which is needed to be realized by a plurality of network equipment can be intuitively displayed, and the configuration speed of the networking information can be improved when more network equipment are used for networking.

And 304, determining the network topology formed on the topology editing page as a simulated network topology corresponding to the networking scheme.

In one embodiment of the present invention, after step 304, the generated simulated network topology corresponding to the networking scenario may be stored in a library of simulated network topologies for subsequent use.

This step 202 uses a second approach to obtain a simulated network topology.

The simulated network topology obtained using the first approach may be stored, for example, in a library of simulated network topologies, which may then include a plurality of simulated network topologies for selection.

Referring to fig. 4, the step 202 may include:

step 400, determining whether a simulated network topology corresponding to the networking scheme exists in a pre-generated simulated network topology library, and if so, executing step 402; if not, go to step 404.

In one embodiment of the present invention, when the simulated network topology is stored in the simulated network topology library, the networking scheme corresponding to the simulated network topology can be stored together. For example, the number, type, networking division, etc. of network devices in the networking scheme are stored. So that the user can quickly learn whether the required analog network topology exists in the analog network topology.

If changes to the networking are required frequently within an enterprise, and the scope of the changes includes a fixed number of networking schemes, then the simulated network topology for each networking scheme may be stored in a library of simulated network topologies. When each time of change, the simulated network topology corresponding to the networking scheme can be directly exported from the simulated network topology library, so that the networking change efficiency can be improved, and the networking change cost can be saved.

Step 402, deriving the simulated network topology corresponding to the networking scheme from the simulated network topology library.

Step 404, generating a simulated network topology corresponding to the networking scheme.

In step 404, a simulated network topology corresponding to the networking scheme is generated, which is the same as the first mode described above and will not be described in detail herein.

Step 204, generating a networking password according to the simulated connection relation included in the simulated network topology and networking information of each network device.

In the embodiment of the invention, after the simulated network topology is formed, a user can initiate an instruction for mapping the simulated network topology to the entity network topology, after the system receives the instruction, the simulated network topology can be identified, the content related in the simulated network topology can be identified, such as the simulated connection relation, networking information of each network device and the like, and then a networking password which can be identified by the switch is generated according to the identified content.

In one embodiment of the present invention, the identifying manner of the networking information of the network device may include: directly acquiring text elements of equipment encapsulation, and extracting networking information of corresponding network equipment of the equipment encapsulation from the text elements.

In one embodiment of the present invention, the identifying manner of the analog connection relationship may include: acquiring the corresponding relation between each equipment package and the connection element; determining a connection relationship between a plurality of device packages according to the correspondence relationship; the connection relationship between the plurality of device packages is determined as the analog connection relationship.

For example, if the device package S01001 interface has a correspondence relationship with the connection element L001 and the device package S02001 interface also has a correspondence relationship with the connection element L001, it may be determined that the device package S01001 interface has a connection relationship with the device package S02001 interface according to the connection element L001.

When the correspondence between each device package and the connection element is obtained, the correspondence may be directly obtained from the package information of the device package (the correspondence is stored in the package information in step 300). The detection method in step 300 may also be used to detect the device package, so as to obtain the correspondence between the device package and the connection element.

Examples of a portion of the identified content are given below:

device type: switch board

Identification information of the device: s01

Identification information of interface 1: s01001

Identification information of the device to which the interface 1 is connected: d01001

Type of device to which interface 1 is connected: computer with a memory for storing data

Type of device to which interface 2 is connected: computer with a memory for storing data

Type of interface of the device to which the interface 2 is connected: net mouth

Device type: computer with a memory for storing data

Identification information of the device: d01

Identification information of the device to which the interface 1 is connected: s01001

Type of device to which interface 1 is connected: switch board

VLAN information to which the device belongs: VLAN1

IP address of device: 168.192.0.1

Login account number of device: 111111

Login password of device: 222222

……

In one embodiment of the invention, since the identifiable networking passwords are different when the types of the switches are different, different networking passwords need to be generated for different switches when generating the networking passwords. Specifically, this step 204 may include:

S1: according to the simulated connection relationship, determining at least one network device connected with a target switch in the at least one switch, and determining information of an interface of the target switch connected with the at least one network device.

For example, the switch S01, the network devices connected thereto include a device D01 and a device D02, and the device D01 is connected using the S01001 interface of the switch, and the device D02 is connected using the S01002 interface of the switch.

S2: and determining attribute information of the target switch and information of a virtual local area network to which the at least one network device belongs according to networking information of each network device.

The attribute information of the target switch may include vendor information, model information, and the like.

When determining the information of the virtual local area network to which the at least one network device belongs, the information of the virtual local area network to which the device D01 belongs may be determined by the networking information of the network device, for example, the information of the virtual local area network to which the device D01 belongs is VLAN1, and the information of the virtual local area network to which the device D02 belongs is VLAN2.

S3: and determining the password type which can be identified by the target switch according to the attribute information of the target switch.

Wherein, a correspondence between the switch attribute information and the identifiable password type may be established in advance, and after the attribute information of the target switch is determined in S2, the identifiable password type of the target switch may be determined directly according to the correspondence.

S4: generating a networking password corresponding to the target switch according to the information of the interface of the target switch and the at least one network device, the information of the virtual local area network to which the at least one network device belongs and the password type which can be identified by the target switch.

After determining the networking scheme, the content of generating the networking password for the switch may be implemented by existing schemes, which are not described in detail herein.

In the embodiment of the invention, the identifiable password types of the switches can be determined according to the attribute information of the switches in consideration of the fact that the identifiable password types of different switches possibly can be identified, so as to generate the identifiable networking password aiming at the interaction machine, thereby ensuring the successful networking.

And step 206, the networking port command is sent to the at least one switch, so that the at least one switch executes the networking password to network the entity network topology formed by the plurality of network devices according to the networking scheme, wherein the entity connection relationship between the plurality of network devices in the entity network topology is the same as the simulated connection relationship.

When more than two switches are included in the plurality of network devices, the generated networking port command corresponding to the switch can be sent to the corresponding switch. When the switch receives the networking password, the networking password may be executed, thereby completing networking.

The above steps 200-206 complete the networking of the physical network topology.

It should be noted that, other networking modes besides the networking mode described in fig. 2 may be used, for example, a manual networking mode, that is, after the networking scheme is determined, the operation and maintenance personnel directly and manually configure the switch to implement networking.

In one embodiment of the present invention, the physical network topology in step 100 may be mapped from the above-described simulated network topology. For example, the entity network topology after networking in steps 200 to 206 is the entity network topology to be detected in step 100.

Then, for step 102, networking information corresponding to each of the plurality of network devices is obtained.

In step 102, in order to implement state detection of each network device in the entity network topology, networking information of each network device in the entity network topology needs to be acquired, where the networking information may be input by an operation and maintenance personnel; the networking information of each network device in the entity network topology can be stored in advance, and the networking information can be directly read from a storage position when the networking information is needed; in addition, the network topology can be obtained through a simulated network topology corresponding to a networking scheme realized by the entity network topology.

When the network device is acquired through a simulated network topology corresponding to a networking scheme realized by an entity network topology, specifically, the packaging information of the device packages corresponding to the network devices is acquired from the simulated network topology, the packaging information comprises networking information, and the networking information of the network device is extracted from the packaging information.

Finally, for step 104, according to the networking information respectively corresponding to the plurality of network devices, creating a virtual detection device belonging to the same virtual local area network as each network device, and initiating access to the plurality of network devices by using the virtual detection device so as to determine the state of each network device according to the access result.

In the embodiment of the present invention, the number of created virtual detection devices may correspond to two cases:

case one: a virtual detection device is created.

And a second case: at least two virtual detection devices are created.

The implementation process of this step will be described below for the above two cases, respectively.

In a first case, referring to fig. 5, the initiating access to the plurality of network devices by the virtual detection device in step 104 may include:

and 500, determining at least one virtual local area network corresponding to the plurality of network devices according to networking information of each network device.

Step 502, determining whether there is an undetected virtual local area network in the at least one virtual local area network, and if so, executing step 504; if not, the detection is ended.

In step 504, a virtual lan is selected from the undetected virtual lans as a target virtual lan, and at least one network device belonging to the target virtual lan and the IP address corresponding to the at least one network device are determined.

Step 506, an IP address belonging to the target virtual lan is allocated to the virtual detection device;

step 508, respectively initiating access to the at least one network device by using the IP address of the virtual detection device and the IP address corresponding to the at least one network device, determining the target virtual local area network as the detected virtual local area network after initiating access to the at least one network device, and returning to step 502.

For example, 10 hosts belonging to different VLANs can be known from the networking information, wherein hosts 1 to 3 belong to VLAN1, hosts 4 to 6 belong to VLAN2, and hosts 7 to 10 belong to VLAN3. Firstly, VLAN1 is determined as a target VLAN, network equipment belonging to the VLAN1 is determined as hosts 1-3, IP addresses of the hosts 1-3 can be determined, the IP addresses belonging to the VLAN1 are allocated to virtual network equipment, and at the moment, the virtual network equipment and the hosts 1-3 belong to the VLAN1, so that the virtual network equipment can respectively initiate access to the hosts 1-3, and the states of the hosts 1-3 can be determined according to access results. Then, VLAN2 is determined as the target VLAN and VLAN3 is determined as the target VLAN, and the processing after VLAN2 and VLAN3 are determined as the target VLAN is the same as that of VLAN 1. Finally, access results corresponding to the hosts 1 to 10 can be obtained.

It should be noted that, in step 502, it may be determined whether an undetected virtual lan exists in the at least one virtual lan by means of an identifier or the like. For example, the detected virtual local area networks are marked with a special identifier, and a virtual local area network which is not marked with the identifier in the at least one virtual local area network is determined as an undetected virtual local area network. For another example, the determination may be made by packet format, where the codes of each VLAN are added to a packet before access is not initiated to any network device in the VLAN, for example, VLAN1, VLAN2 and VLAN3 are added to the same packet, the VLAN in the packet is an undetected VLAN, and a VLAN is randomly extracted from the packet and is used as a target VLAN until the VLAN is not included in the packet.

By using the virtual detection device created in the first case to detect the plurality of network devices, the virtual detection device is convenient to manage, and the detection cost is low.

In the second case, the plurality of network devices correspond to at least two virtual local area networks, and the at least two virtual detection devices correspond to the at least two virtual local area networks one by one.

Referring to fig. 6, in step 104, when the virtual detection apparatus is used to initiate access to the plurality of network apparatuses, the method may include:

step 600, determining at least one network device belonging to a target virtual local area network of the at least two virtual local area networks, and IP addresses corresponding to the at least one network device respectively.

Step 602, allocating an IP address belonging to the target virtual local area network to a target virtual detection device corresponding to the target virtual local area network, and respectively initiating access to the at least one network device by using the IP address of the target virtual detection device and the IP address respectively corresponding to the at least one network device.

For example, 10 hosts belonging to different VLANs can be known from the networking information, wherein hosts 1 to 3 belong to VLAN1, hosts 4 to 6 belong to VLAN2, and hosts 7 to 10 belong to VLAN3. Then 3 virtual detection devices are created, namely virtual detection device a, virtual detection device B, virtual detection device C, wherein virtual detection device a corresponds to VLAN1, virtual detection device B corresponds to VLAN2, and virtual detection device C corresponds to VLAN3. Since the execution mode is the same for each of VLANs 1 to 3, VLAN1 will be described as an example. The network equipment belonging to VLAN1 is host 1-3, obtain the IP address of host 1-3, then assign the IP address belonging to VLAN1 for virtual detection equipment A, and utilize virtual detection equipment A to initiate access to host 1-3 respectively, so as to obtain the access result of host 1-3.

By creating at least two virtual detection devices in the second case, the at least two virtual detection devices are in one-to-one correspondence with at least two virtual local area networks, and each virtual detection device is used for detecting network devices in the corresponding virtual local area network, detection efficiency can be improved.

It should be noted that, whether the above case one or the case two, the obtaining manner of the IP address of the network device may be an IP address configured when performing the configuration of the networking information for each network device in the simulated network topology when the simulated network topology is generated, and then directly obtaining the IP address of each network device according to the networking information; the IP address may also be obtained from the switch after networking.

In one embodiment of the present invention, the determining the status of each network device according to the access result in step 104 may include: and determining the state of the network equipment corresponding to the successful access initiation result as online, and determining the state of the network equipment corresponding to the failed access initiation result as offline.

In one embodiment of the present invention, after determining the state of each network device, the virtual detection device may send the state of each network device to the detection platform (the detection platform may create the virtual detection device and initiate a detection instruction to the virtual detection device, so that the virtual detection device completes the platform end of the detection process according to the detection instruction), and the detection platform may automatically fill the state of each network device into the encapsulation information of the device packages corresponding to each network device in the simulated network topology, so that the user may view the state of the corresponding network device according to the encapsulation information of the device packages.

In one embodiment of the present invention, the method for initiating the access includes: at least one of a ping mode, a web server mode, a simple file transfer protocol TFTP mode and a ssh telnet mode.

The virtual detection device initiates an access to the host 1, and the method of initiating an access is described by taking a ping method as an example. The virtual detection device sends a ping packet to the host 1, and if the host 1 returns information for the ping packet, the virtual detection device indicates that the access initiation is successful, and the host 1 is online; if host 1 is unresponsive, then this indicates that the initiating access failed, and host 1 is offline.

Preferably, the maximum access times can be set when the access is initiated, for example, the maximum access times are set to 3 times, if no reaction is caused when the access is initiated to the same network device for 3 times, the network device is determined to be offline, so that the accuracy of the access result can be improved.

For step 106, it is determined whether the physical network topology is successful in networking according to the status of each network device.

And when the states of the plurality of network devices are all online, determining that the entity network topology is successful in networking according to the networking scheme, otherwise, determining that the entity network topology is failed in networking according to the networking scheme. For example, in the hosts 1 to 10, the hosts 1 to 9 are all on-line, and the host 10 is off-line, indicating a networking failure.

In one embodiment of the present invention, the types of the network devices may include: physical network devices and/or virtual network devices.
