Detailed Description
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The network configuration recovery method can be applied to a network management server, which can be the network management system, as shown in fig. 3, the network management server can manage network nodes (or referred to as Network Elements (NEs)) in a network domain, the network management server is connected to each network node, and can issue parameters or instructions to the network nodes, so as to establish multiple types of network connection services for different devices or different sites.
The network element may be a network element, or a component in the network element (e.g., a port component in the network element), which is not limited in this embodiment of the present invention. The network element may be: passive Optical Network (PON) network elements, Optical Transport Network (OTN) network elements, Internet Protocol (IP) network elements, or microwave network elements, and the like. The network elements may specifically be switches, routers, gateways, etc. Further possible scenarios are not described in detail herein.
For example, the multiple types of network connection services may be divided into multiple types according to different connection objects, and the multiple types may include: the internet access service system comprises two major types of network connection services, namely an internet dedicated line service and an internet dedicated line service, wherein the internet dedicated line service is used for connecting a plurality of terminals, and the internet dedicated line service is used for accessing the terminals into the internet. Each company can have a plurality of branch companies, and the plurality of branch companies can subscribe the special line-of-interconnection service to interconnect terminals of the plurality of branch companies, so that the terminals of the plurality of branch companies can communicate conveniently. As shown in fig. 1, a network station a is connected to a network station B through the network node a, the network node B, and the network node C in fig. 1 to form a dedicated interconnection line for terminal communication between the network station a and the network station B, and the network station a may also be connected to the network station C through the network node a, the network node B, and the network node D in fig. 1 to form a dedicated interconnection line for terminal communication between the network station a and the network station C. Further, each company may also subscribe to dedicated internet services to enable terminals in the company to access the internet, thereby facilitating access to the internet by the terminals of the company. Referring to fig. 1, the network station a is connected to the internet through the network node a, the network node B, and the network node E in fig. 1, so as to form a dedicated internet line for the terminal of the network station a to access the network.
Alternatively, the network connection service may be based on any communication technology, for example, a layer2virtual private network (L2 VPN) technology or a layer 3virtual private network (L3 VPN) technology, and the like.
Based on the connection relationship between the network management server and the network node, fig. 4 shows a network configuration recovery method according to the present application. Fig. 4 illustrates 4 configurations, and the number of configurations in which actual services exist is not limited, and fig. 4 is merely used as an exemplary illustration. As shown in fig. 4, the network management server needs to perform configuration 1 in order to create the first service, and store network intention data set 1 and network implementation data 1 in the database, then modify the first service in sequence, perform configuration 2, configuration 3, and configuration 4, respectively, and store network intention data set 2 to network intention data set 4 and network implementation data 2 to network implementation data 4 in the database. If an operator (or a network management server manager) finds that the configuration 3 and the configuration 4 have problems and needs to be restored to the configuration 2, it can be found by referring to fig. 2 and fig. 4, that the network management server copies the network intention data set 2 of the configuration 2 and then obtains the network implementation data 5 based on the network intention data set 2 for configuration restoration, instead of directly rolling back to the network implementation data 2 corresponding to the configuration 2 for restoration in the prior art. The solution of the present application is explained in detail below with reference to fig. 5:
the dedicated network line is also called as a private line or a leased line, and the dedicated network line refers to an independent network line, i.e. an independent local area network, pulled for an organization, and the leased line service is one of the most important services in the service of the operator B2B (business-to-business).
Network configuration refers to the configuration of devices or interfaces in a network by a network engineer.
First, it should be noted that, after the network management server performs a certain configuration on the service, that is, the network management server obtains the configured network node configuration information based on the configured network intention data set, the network management server issues a configuration instruction to the network node according to the network node configuration information, so that the network node performs configuration according to the configuration instruction. The configuration, the network intention data set and the network implementation data have one-to-one correspondence, and the network intention data set and the network implementation data corresponding to each configuration are stored in the database. The network intent may be said to be the user's intent or business goal for the network private line, or may be said to be the network operator's intent for the network private line, or may be said to be the network operation and maintenance person's or network architect's intent for the network private line based on the network operator's needs. The network intention data is requirement information of a network operator or a user on a network special line, and the requirement information can be requirement information of the network operator or the user for establishing the network special line from one network station to another network station, for example, in order to establish the network special line from the network station A to the network station B in the figure 1, data of the network station A and data of the network station B need to be provided, and the network intention data comprises one or more items of an IP address, a subnet mask, a bandwidth, a routing strategy and a bandwidth adjusting strategy (QAS) of a starting station in the network special line, and one or more items of an IP address, a subnet mask, a bandwidth, a routing strategy and a bandwidth adjusting strategy of a terminating station. The network operator may request that one or more network private lines be established, and the set of network intention data may include one or more network intention data. The network implementation data refers to data that needs to be configured by network nodes in a dedicated network line in order to establish the one or more dedicated network lines, for example, data that needs to be configured by network node a, network node B, and network node C in order to establish a dedicated network line between network station a and network station B in fig. 1, and the number of network nodes in a certain dedicated network line is not limited. It can be understood that, in the present application, the network implementation data of a certain configuration and the configuration information of a certain configuration may be regarded as equivalent concepts, and both are used for the network node in this configuration to perform parameter configuration, specifically including a network node ID and a configuration parameter corresponding to the network node ID.
Step 501, the network management server obtains at least one network intention data set stored in advance.
After finding that a certain configuration of the first service is wrong, an operator decides to restore the second configuration of the first service at the current moment to the first configuration of the historical moment, the operator issues a configuration restoration request to a network management server, and the network management server acquires at least one network intention data set stored in advance according to the configuration restoration request. The operator is a person operating the network management server, and may also be a manager of the network management server, and further other names are not repeated herein.
Step 502, the network management server receives a selection instruction of a target network intention data set in at least one network intention data set.
An operator selects a target network intention data set corresponding to a first configuration from the network intention data sets on a network management server interface, the network management server receives a selection instruction of the target network intention data set after the operator selects the target network intention data set, and the operator needs to confirm each network intention data in the target network intention data set so as to ensure that the network intention to be recovered is correct, and the target network intention data set belongs to at least one network intention data set.
Step 503, the network management server determines the first configured network node configuration information according to the target network intention data set.
The network management server recalculates the network node configuration information of the first configuration according to the target network intention data set, instead of directly acquiring network implementation data which is stored in advance by the network management server and corresponds to the target network intention data set, and when the network management server recalculates the network node configuration information of the first configuration, the network management server can select the network node configuration information of the first configuration from the network resources which are not distributed yet, so as to avoid the conflict with the network resources occupied by other services in the network.
Step 504: and the network management server sends a parameter configuration instruction to the network node corresponding to the first configuration and/or the network node corresponding to the second configuration according to the network node configuration information of the first configuration.
One, one possible scenario is: in this embodiment, the network node corresponding to the second configuration needs to delete the network configuration parameters, that is, the network node corresponding to the first configuration performs reconfiguration according to the matching instruction of the first configuration, which is equivalent to a full-scale issuing manner, so that all the network nodes corresponding to the first configuration perform parameter configuration.
Two, another possible scenario is: comparing the configuration information of the first configuration with the configuration information of the second configuration to obtain a configuration difference of the target network node, and sending a configuration instruction to the target network node according to the configuration difference of the target network node, where the target network node is a network node having a configuration difference between the first configuration and the second configuration, and this embodiment is equivalent to performing parameter configuration only on differentiated network nodes, and specifically there are some positive cases as follows:
first, the target network node may be one or more network nodes corresponding to the first configuration, the target network node may also be one or more network nodes corresponding to the second configuration, and the target network node may also be one or more network nodes corresponding to the first configuration and one or more network nodes corresponding to the second configuration. If the same target network node exists between the network node corresponding to the first configuration and the network node corresponding to the second configuration, but the parameter configurations of the target network nodes are different, the network management server issues a configuration modification instruction to the target network node in the first configuration or the target network node in the second configuration, that is, the network management server can send the configuration instruction to one or more network nodes corresponding to the first configuration or one or more network nodes corresponding to the second configuration; if the network node corresponding to the first configuration comprises a target network node and the network node corresponding to the second configuration does not comprise the target network node, the network management server issues a configuration increasing instruction to the target network node in the first configuration, that is, the network management server can send the configuration instruction to one or more network nodes corresponding to the first configuration; the network node corresponding to the second configuration includes a target network node, and the network node corresponding to the first configuration does not include the target network node, the network management server issues a delete configuration instruction to the target network node in the second configuration, that is, the network management server may send the configuration instruction to one or more network nodes corresponding to the second configuration, where one or more of the situations may exist at the same time, that is, the network management server may send the configuration instruction to one or more network nodes corresponding to the first configuration and one or more network nodes corresponding to the second configuration. In summary, the network management server may send a parameter configuration instruction to one or more network nodes corresponding to the first configuration and/or one or more network nodes corresponding to the second configuration, and a network node may receive one or more configuration instructions, where the configuration instruction may be a modification configuration instruction, a deletion configuration instruction, and/or an addition configuration instruction.

Meanwhile, in this embodiment, when the second configuration at the current time is restored to the first configuration, a possible situation is that the configuration information of the second configuration and the configuration information of the first configuration have the same part, so that, compared with a scheme of directly restoring network implementation data corresponding to the configuration in the prior art, the network management server issues a configuration instruction based on the network implementation data corresponding to the configuration, and the amount of data that needs to be restored by a network node is huge. 3.

One possible application scenario is: the network management server at the initial moment executes the first configuration to establish the network leased line from Wuhan to Shenzhen, and the network management server at the current moment executes the second configuration to modify the network leased line configuration from Wuhan to Shenzhen, so that the configuration at the initial moment needs to be restored.

In the case that the configuration information of the target network node in the first configured network node configuration information is different from the configuration information of the target network node in the second configured network node configuration information, the service execution module 604 issues a configuration modification instruction to the target network node, specifically: as shown in the above table, the VLAN number of the router R2 in the configuration information of the first configuration is 26, the VLAN number of the router R2 in the configuration information of the second configuration is 25, and the VRF and the service port IP address of the router R3 also exist in the configuration information of the second configuration, the service execution module 604 searches the IP address of the router R2 in the base inventory module 607 according to the ID of the router R2, the service execution module 604 determines the location of the router R2 according to the IP address of the router R2, and invokes an interface of the router R2 to issue an instruction to modify the VLAN number of the router R2 from 25 to 26.
