In view of the above problems, the present application proposes the following embodiments to solve the above problems. The embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
First embodiment
Referring to fig. 1, a network system provided by an embodiment of the present application may include a plurality of Software Defined Perimeter (SDP) servers. Some of the plurality of SDP servers may operate in the role of controllers and the remaining servers may operate in the role of gateways. In addition, a plurality of SDP servers can be automatically networked to form an SDP network architecture.
The operating role of one SDP server may be a gateway, or a controller, or both a gateway and a controller. The server operating as a gateway role can be used as gateway equipment for realizing network interconnection above a network layer and for interconnecting two networks with different high-level protocols. The server operating as the controller role can be used for detecting and analyzing the operating conditions of each server in the network and performing switching control on the operating roles of the servers.
The user terminal can realize corresponding data access through the SDP network architecture. For example, an enterprise deploys an SDP network architecture for storing business or network resources related to the enterprise, and employees of the enterprise can access the corresponding business or network resources through the SDP network architecture.
The user terminal may be, but is not limited to, a smart phone, a Personal Computer (PC), a tablet PC, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and the like.
The application also provides a server which can comprise a processing module, a storage module and a communication module. Wherein the storage module may store therein a computer program that, when executed by the processing module, may enable the server to perform the steps of the networking method described below. The communication module is used for establishing communication connection between the server and other servers and the user terminal.
Referring to fig. 1 again, the servers may be a first server 10 and a second server 20 described below. Both the first server 10 and the second server 20 are SDP servers, which may operate in the role of a controller, or a gateway, or both. Each server is allowed access.
Referring to fig. 2, an embodiment of the present application further provides a networking method, which can be applied to the network system, and each step in the method is executed by a corresponding server. The method may comprise the steps of:
step S110, when the second server is started, the second server sends a first broadcast message to a server in the local area network;
step S120, the first server receives a first broadcast message sent by a second server in the local area network when the second server is started;
step S130, the first server sends a first notification message to the second server according to the first broadcast message;
step S140, the second server controls the second server to register in a designated role according to the first notification message sent by the first server, wherein the designated role is a gateway and/or a controller;
step S150, the second server sends a second notification message to the first server;
step S160, when the first server receives a second notification packet of the second server, and the second notification packet indicates that the second server is successfully registered in the designated role, updating networking registration information, where the updated networking registration information includes gateway list information and controller list information, the gateway list information includes identity information of all servers currently serving as gateways, and the controller list information includes identity information of all servers currently serving as controllers.
In the foregoing embodiment, the second server may automatically send the broadcast message when being started, so that the first server serving as the controller receives the broadcast message, and then the first server controls the second server to perform networking registration in a designated role. Based on the method, the automatic deployment of the SDP server can be realized, and the problems of misoperation risk and low efficiency caused by manual deployment are reduced.
The individual steps of the process are explained in detail below, as follows:
in step S110, the second server is one or more servers that currently need to be networked, and is not limited to one server. For example, when the load of the current SDP network framework is large and a new SDP server needs to be accessed to share the processing pressure, one or more SDP servers are started for networking. And the started SDP server needing networking is the second server.
And the second server physical line is connected in the set local area network in advance. The set local area network can be deployed according to the actual situation. For example, the configured lan may be a lan of an enterprise. When the second server is started, the first broadcast message can be automatically broadcast to all servers in the local area network to be sent. The first broadcast message is used for requesting the second server to perform SDP networking.
The first broadcast message may include, but is not limited to, identity information of the second server itself, hardware parameters, and the like. The identity information includes, but is not limited to, an IP address, a MAC address, etc. of the second server for identifying the identity of the second server. The hardware parameter information may include, but is not limited to, a capacity size of a storage space of the second server, a CPU (Central Processing Unit) parameter, a GPU (Graphics Processing Unit) parameter, and the like.
The mode of the second server for transmitting the first broadcast message can be selected according to actual conditions. For example, the second server may broadcast the first broadcast packet in a UDP (User Datagram Protocol).
In step S120, since the second server transmits the first broadcast packet in a broadcast manner, the first broadcast packet may be received by the first server. The first server is an SDP server running in a controller role.
In step S130, after receiving the first broadcast packet, the first server may analyze and process the request information and the identity information carried in the first broadcast packet. For example, when the first broadcast message includes a request content for networking, the first server sends a first notification message to the second server, where the first notification message is used to control the second server to register in a designated role and then operate in the designated role. If the broadcast message does not include the request content for networking, the first server does not need to send the first notification message to the second server.
In step S140, after receiving the first notification message, the second server may parse the first notification message. For example, if the first notification message includes content that permits the second server to perform networking registration in a designated role, the second server controls itself to perform networking registration in the designated role. The designated role can be a gateway, or a controller, or both.
When the second server registers in the gateway role, the second server starts the service process corresponding to the gateway. When the second server registers in the controller role, the second server starts the corresponding service process of the controller. When the second server registers with the controller and the gateway, the second server starts the gateway and the service process corresponding to the controller at the same time. And presetting service processes corresponding to the gateway and the controller in the second server and other SDP servers in the local area network.
In step S150, after the second server completes the networking registration (e.g., the second server starts a service process corresponding to the designated role), the second server may send a second notification message to the second server, where the second notification message is used to indicate that the second server is successfully registered in the designated role.
In step S160, after receiving the second notification packet of the second server, the first server may parse the second notification packet. For example, if the second notification message includes content indicating that the second server has successfully registered in the designated role, the group network registration information is updated. If the second notification message does not include the content indicating that the second server is successfully registered in the designated role, the networking registration information does not need to be updated.
After the networking registration information is updated, the successful networking of the second server to the SDP network architecture is indicated, and the second server can provide corresponding services in a designated role. For example, if the designated role is gateway, the second server may provide gateway services. If the designated role is controller, the second server may provide control services.
It should be noted that, in the process of networking in the SDP network architecture, the first networked server generally designates a server for an administrator. The server may act as both a controller and a gateway. Then, the administrator starts other servers in the network, and the started other servers perform the networking operation as the second server.
As an alternative implementation, step S160 may include: when a second notification message of the second server is received and the second notification message represents that the second server is successfully registered in the designated role, adding the identity information of the second server to networking registration information stored by the first server so as to update the networking registration information; and broadcasting a second broadcast message to the local area network, wherein the second broadcast message is used for controlling each server corresponding to the networking registration information to update the networking registration information stored by the server.
Understandably, when the networking registration information is updated, the first server may add the identity of the second server to the networking registration information stored in advance to obtain the updated networking registration information. After the first server finishes updating the local networking registration information, the first server can also send the identity information of the second server to other networked services in the local area network in a broadcasting mode so that the other servers update the networking registration information of the first server. Or, the first server may send the updated networking registration information to a server already networked in the local area network in a broadcast manner.
For example, when the designated role is a gateway, the first server may add the identity information of the second server in the gateway list information. Then, the first server sends the identity information of the second server and the gateway role to other servers in a broadcasting mode, so that the other servers add the identity information of the second server to respective gateway list information to indicate that the second server successfully performs networking in the gateway role.
When the designated role is the controller, the second server may add the identity information of the second server in the controller list information. Then, the first server sends the identity information of the second server and the controller role to other servers in a broadcast mode, so that the other servers add the identity information of the second server to respective controller list information to indicate that the second server successfully performs networking in the controller role.
Understandably, each server in the networking stores the networking registration information. The networking registration information needs to be updated synchronously with the networking registration information of the server operated by the controller. When there are multiple servers operated by the controller, the multiple controller servers may negotiate one server as a master control server, and the other servers as slave control servers, and the first server may be the master control server, and the negotiation manner is well known to those skilled in the art and will not be described here. The networking registration information of the master control server can be used as source information of synchronous update.
As an alternative embodiment, the first step S130 may include:
acquiring a first average load of a server serving as a controller in all servers in a current network and a second average load of a server serving as a gateway;
when the first average load is smaller than the second average load, sending the first notification message to the second server for controlling the second server to register in a gateway role;
and when the first average load is greater than or equal to the second average load, sending the first notification message to the second server for controlling the second server to register in a controller role.
In this embodiment, the load may be a load of the server during operation. For example, the load may include, but is not limited to, CPU usage, GPU usage, memory occupancy, and the like. For example, when the load is the utilization rate of the CPU, the first average load may be calculated by: the sum of the CPU utilization rates of the service processes providing the controller in each server among the servers serving as the controller, divided by the number of servers serving as the controller, can be calculated by the following equation (1):
CPU_controller＝(CPU_controller_1+…+CPU_controller_m)/m (1)
in formula (1), CPU _ controller refers to the first average load, CPU _ controller _ m is the CPU usage of the mth server, and m is the total number of servers operating as controllers, and is an integer greater than 0.
The second average load may be calculated by: the sum of the CPU utilization rates of the service processes providing the gateway in each server among the servers serving as the gateway, divided by the number of servers serving as the gateway, can be calculated by the following equation (1):
CPU_gateway＝(CPU_gateway_1+…+CPU_gateway_n)/n (2)
in formula (1), CPU _ gateway refers to the second average load, CPU _ gateway _ n is the CPU usage of the nth server, and n is the total number of servers operating as the controller, and is an integer greater than 0.
When the first average load is smaller than the second average load, it indicates that the processing load of the gateway is greater than the processing load of the controller, so that more servers are currently required to serve as gateways to share the current gateway load, and at this time, the second server needs to register in a gateway role. I.e. the designated role is gateway.
When the first average load is greater than or equal to the second average load, it indicates that the processing load of the gateway is smaller than the processing load of the controller, and therefore, more servers are currently required to serve as the controller to share the current controller load, and at this time, the second server needs to register in a controller role. I.e. the role is designated as controller.
Based on the design, the load balance between the server serving as the controller and the server serving as the gateway can be ensured as much as possible, and the average load difference between the server serving as the controller and the server serving as the gateway is reduced, so that the stability of the SDP network architecture is improved.
As an optional implementation, the method may further include:
acquiring a third notification message sent by each server in the networking in a preset period, wherein the third notification message comprises load information of each server;
when the third notification message sent by the designated server is not acquired within a preset time length, deleting the identity information of the designated server from the networking registration information of the first server, and notifying the server in the local area network to update the networking registration information of the server, wherein the preset time length is longer than the preset period, and the designated server is any server excluding the first server from the networking registration information.
In this embodiment, after each server successfully networks, the third notification message may be periodically sent to the first server. The third notification message may be a heartbeat message, and is used to notify load information of each current server in the first server networking. The load information includes, but is not limited to, the CPU utilization, the memory occupancy, and the like. The preset time length and the preset period may be set according to actual conditions, and are not specifically limited herein.
When the third notification message sent by the designated server is not received by the first server within the preset time length, the first server usually indicates that the designated server is abnormal. At this time, the identity of the designated server needs to be deleted from the networking registration information to remove the designated server from networking. Therefore, the SDP network architecture can automatically delete the abnormal server so as to improve the stability of the network architecture. The designated server may be any server in the networking, and is not particularly limited herein.
As an optional implementation, the method may further include:
receiving a third broadcast message sent by the appointed server when the appointed server is started;
sending a fourth notification message to the designated server according to the third broadcast message, wherein the fourth notification message is used for controlling the designated server to register in a designated role;
and updating networking registration information when a fifth notification message of the designated server is received and the fifth notification message represents that the designated server successfully registers the gateway.
After the specified server is abnormal, the first server may send a prompt indicating that the specified server is abnormal to the management terminal. The administrator can restart the designated server according to the exception prompt. Or the first server can automatically control the designated server to restart after the designated server is abnormal.
After the designated server is restarted, the designated server and the first server may cooperate with each other, and step S110 to step S160 are re-executed to re-network the restarted designated server. The function of the third broadcast message is similar to that of the first broadcast message, the function of the fourth notification message is similar to that of the first notification message, and the function of the feature notification message is similar to that of the second notification message, which are not described herein again.
As an optional implementation, the method may further include:
when the load of a server serving as a controller in the local area network is greater than or equal to a first specified load, selecting a server with the minimum load and less than or equal to a second specified load to be switched to the controller from the gateway according to the load information of each server currently serving as the gateway, wherein the second specified load is less than the first specified load;
when the load of a server serving as a gateway is larger than or equal to a third specified load and at least two servers serving as controllers exist in the local area network, selecting the server with the minimum load and smaller than or equal to a fourth specified load to be switched to the gateway by the controller according to the load information of each server currently serving as the controller, wherein the fourth specified load is smaller than the third specified load.
The first specified load represents that the load of the server as a controller exceeds a normal load value, and the second specified load represents that the load of the server is at a relatively idle value. The third specified load represents that the load of the server as the gateway exceeds a normal load value, and the fourth specified load represents that the load of the server is at a relatively idle value. The first and third specified loads may be the same or different, and the second and fourth specified loads may be the same or different.
For example, the first specified load may be 2 times the average load of the servers as gateways. If the load of the server serving as the controller is greater than or equal to 2 times of the average load of the gateway servers, the load of the server is considered to be too large, and a server serving as the controller needs to be added to share the load of the controller.
The mode of the server of the newly added controller can be as follows: the server with the load which is the smallest and is less than or equal to the second specified load is selected as the target server from the servers which are currently used as the gateway, and then the target server is switched from the gateway role to the controller role, namely, the target server is switched from the gateway service process to the controller service process, so that the processing load of the server which is used as the controller and has the overlarge load can be shared.
For another example, the third specified load may be 2 times the average load of the server as the controller. If the load of the server serving as the gateway is greater than or equal to 2 times of the average load of the controller servers, the load of the server is considered to be overlarge, and a server serving as the gateway needs to be added to share the load of the gateway.
The method for adding the server of the gateway can be as follows: if the number of servers as controllers in the local area network is greater than or equal to 2, a server with the minimum load and less than or equal to a second specified load is selected as a target server from the servers currently serving as the controllers, and then the target server is switched from the controller role to the gateway role, that is, the target server is switched from the controller service process to the gateway service process, so that the processing load of the server which serves as a gateway and has an excessive load can be shared.
It should be noted that, in the local area network, each server in the networking periodically reports its own load information to the first server, which is beneficial for the first server to grasp the load condition of each server in time, so as to switch the roles of the servers according to the load condition, or add a new server or stop a part of the servers started, so as to dynamically allocate the resources of the servers.
For example, when the load of the server as the controller is too large and one server cannot be switched from the gateway to the controller among the servers as the gateway, a new server is required to be added as the controller. When the load of the server as the gateway is too large and one server cannot be switched from the controller to the gateway in the server as the controller, a new server is required to be added as the gateway. If the idle resources of the plurality of servers as the controller are too much, one or more servers can be stopped according to the actual situation, and the tasks are intensively distributed to one or more servers to execute the related tasks of the controller.

The networking device 200 includes at least one software function module which can be stored in a storage module in the form of software or Firmware (Firmware) or solidified in a server Operating System (OS).
