Detailed Description

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings 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 disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The embodiment of the disclosure provides a route storage method, which is applied to a route storage system. Wherein, the route storage system is shown in fig. 1, the route storage system may comprise network devices 11-13 and a route storage server 14. The route storage system may include a plurality of network devices, and here, only 3 network devices are taken as an example for illustration and are not used for limitation.

The network devices 11-13 establish a connection with the route storage server 14 through a preset network protocol. The pre-network protocol may be one of BGP, ISIS, OSPF, and the like. For example, where the pre-network protocol is BGP, network devices 11-13 establish a BGP neighbor relationship with route storage server 14.

After the network devices 11-13 establish a connection with the route storage server 14, the flow of route storage is shown in fig. 2.

In step S21, the network devices 11-13 acquire routing information of a plurality of gateway protocols stored in the network devices.

In step S22, the network devices 11-13 convert the routing information of the plurality of gateway protocols into target routing information of the preset gateway protocol.

In step S23, the network device 11-13 sends the destination routing information to the preset routing storage server 14 through the preset gateway protocol.

In step S24, the route storage server 14 stores the target route information.

In the embodiment of the disclosure, the network device stores all the routing information into the preset routing storage server through the preset gateway protocol. At this time, the route storage server may store all the route information of the entire network system. The query system can query the required routing information from the routing storage server, the query system only needs to be adapted to the routing storage server, and does not need to be adapted to the network equipment of each manufacturer independently, so that the expandability of the query system is improved, and the problem of poor expandability of the routing query system in the related technology is solved.

Fig. 3 is a flowchart illustrating a route storage method applied to a network device according to an exemplary embodiment, where the route storage method is applied to a network device, as shown in fig. 3, and the method may include the following steps.

In step S31, routing information of a plurality of gateway protocols stored in the network device is acquired.

In the embodiment of the present disclosure, the network device may store routing information of multiple gateway protocols, such as routing information of an OSPF protocol, routing information of an ISIS protocol, routing information of a static protocol, routing information of a BGP protocol, and the like. When the technical scheme provided by the embodiment of the disclosure is implemented, the network equipment stores routing information of a plurality of gateway protocols. The routing information may include a prefix, a next hop, and path information (AS-path) of an Autonomous System (AS).

As shown in fig. 4, the network device 11 stores routing information 1 of the OSPF protocol, routing information 2 of the ISIS protocol, and routing information 3 of the static protocol. When the technical solution provided by the embodiment of the present disclosure is implemented, the network device 11 obtains routing information 1 of the OSPF protocol, routing information 2 of the ISIS protocol, and routing information 3 of the static protocol stored in the network device 11.

In step S32, the route information of the plurality of gateway protocols is converted into the target route information of the preset gateway protocol.

In the embodiment of the present disclosure, the preset gateway protocol is a protocol used for establishing a connection between a network device and a route storage server. For example, if the network device and the route storage server establish a BGP neighbor relationship through BGP, the gateway protocol is preset to BGP.

In one implementation, a network device establishes a BGP neighbor relationship with a storage server. When the network device and the route storage server are located in the same AS, the network device may establish an Internal Border Gateway Protocol (IBGP) neighbor relationship with the storage server, and when the network device and the route storage server are located in different AS, the network device may establish an External Border Gateway Protocol (EBGP) neighbor relationship with the storage server.

In the embodiment of the present disclosure, after acquiring the routing information of multiple gateway protocols, the network device converts the routing information of the multiple gateway protocols into target routing information of a preset gateway protocol.

Still taking the network device 11 in fig. 4 as an example for explanation, the predetermined gateway protocol is BGP. After acquiring the routing information 1 of the OSPF protocol, the routing information 2 of the ISIS protocol, and the routing information 3 of the static protocol, the network device 11 converts the routing information 1 of the OSPF protocol into the target routing information 1 of the BGP, converts the routing information of the ISIS protocol into the target routing information 2 of the BGP, and converts the routing information of the static protocol into the target routing information 3 of the BGP.

In step S33, the target routing information is transmitted to a preset routing storage server through a preset gateway protocol, so that the routing storage server stores the target routing information.

Still taking the network device 11 in fig. 4 as an example for explanation, the network device 11 obtains the target routing information 1-3 of BGP, and sends the target routing information 1-3 to the route storage server through BGP. The route storage server receives the target route information 1-3 and stores the target route information 1-3.

In the embodiment of the present disclosure, the network device may execute the above steps S31-33 regularly, so that the routing information stored in the routing storage server is accurate. The network device may also execute the above steps S31-33 after receiving the route update instruction. The embodiment of the present disclosure is not particularly limited to this.

By applying the technical scheme shown in fig. 3, the network device stores the routing information into the preset routing storage server through the preset gateway protocol. At this time, the route storage server may store all the route information of the entire network system. The query system can query the required routing information from the routing storage server, the query system only needs to be adapted to the routing storage server, and does not need to be adapted to the network equipment of each manufacturer independently, so that the expandability of the query system is improved, and the problem of poor expandability of the routing query system in the related technology is solved.

In addition, in the embodiment of the disclosure, the route information is stored in the route storage server, so that the user can inquire the route information from the route storage server. Under the condition that the routing storage server adopts a database system, the query efficiency of routing information can be effectively improved, and the query efficiency can be improved to ten thousand per second from the original 'hundred pieces per second'. And thirdly, the routing information originally stored in each network device is stored in the routing storage server in a centralized manner, so that the routing table information of the whole network system can be inquired from the routing storage server, and the inquiry mode is simplified.

Fig. 5 is a flowchart illustrating another route storage method applied to a network device according to an exemplary embodiment, where the route storage method is applied to a network device, as shown in fig. 5, and step S33 in the method can be subdivided into steps S331-S332, which are described as follows.

In step S331, a first route update packet of a preset gateway protocol is generated, where the first route update packet carries target route information.

In step S332, the first route update packet is sent to a preset route storage server, so that the route storage server stores the target route information.

After determining the target routing information, the network device generates a first routing update message of a preset gateway protocol, carries the target routing information in the first routing update message and sends the first routing update message to the routing storage server, and then the routing storage server acquires the target routing information from the first routing update message and stores the target routing information.

For example, if the preset gateway protocol is BGP, the first route update packet is a BGP route update packet. After determining the target routing information, the network device generates a BGP routing update message carrying the target routing information, and sends the BGP routing update message to a preset routing storage server. Correspondingly, the route storage server receives a BGP route update message sent by the network equipment, acquires target route information from the BGP route update message, and stores the target route information.

In this embodiment of the present disclosure, each first route update packet may include a piece of target route information, so that the route storage server may quickly acquire and store the target route information in the first route update packet. Each first route updating message may also include multiple pieces of target route information, so as to reduce network resources occupied by the network device sending the route information to the route storage server.

Fig. 6 is a flowchart illustrating another route storage method applied to a network device according to an exemplary embodiment, where as shown in fig. 6, the route storage method is applied to the network device, and in the method, after step S332, step S34 and step S35 may also be performed, as follows.

In step S34, when the route attribute of the first route information in the target route information of the network device changes, a second route update packet of the preset gateway protocol is generated, where the second route update packet carries the first route information and the route attribute after the change of the first route information.

In one implementation, the route attributes may include a first attribute indicating addition of a route and a second attribute indicating withdrawal of the route.

When the network device newly determines that one piece of routing information is the target routing information, the routing information is the first routing information in the target routing information and is a newly added piece of routing information, and the network device generates a second routing update message carrying the first routing information and the first attribute.

When one piece of routing information in the target routing information of the network equipment is updated, the routing information is first routing information in the target routing information, and the network equipment generates a second routing update message carrying the first routing information and a first attribute.

When one piece of routing information in the target routing information of the network equipment fails, the routing information is first routing information in the target routing information, and the network equipment generates a second routing update message carrying the first routing information and a second attribute.

In the disclosed embodiment, the first attribute may be represented using update (update) and the second attribute may be represented using undo (withdraw). The first attribute and the second attribute may also be represented by other characters, which are not specifically limited in this disclosure.

In step S35, the second route update message is sent to the route storage server, so that the route storage server updates the first route information in the route storage server according to the changed route attribute of the first route information.

In one implementation, the route attributes may include a first attribute indicating addition of a route and a second attribute indicating withdrawal of the route. And if the routing attribute carried in the second routing update message is the first attribute, adding the first routing information in the routing storage server by the routing storage server according to the first attribute. And if the routing attribute carried in the second routing update message is the second attribute, the routing storage server cancels the first routing information in the routing storage server according to the second attribute.

In the embodiment of the present disclosure, the second route update message carries the route attribute after the first route information is changed, which can ensure that the route storage server can accurately update the route information, and further ensure that the user can obtain correct route information.

Fig. 7 is a flowchart illustrating a route storage method applied to a route storage server according to an exemplary embodiment, where the route storage method is applied to a route storage server, as shown in fig. 7, and includes the following steps.

In step S71, target routing information sent by the network device is received through the preset gateway protocol, where the target routing information is obtained by converting the stored routing information of multiple gateway protocols by the network device.

In the embodiment of the present disclosure, the network device may store routing information of multiple gateway protocols, such as routing information of an OSPF protocol, routing information of an ISIS protocol, routing information of a static protocol, routing information of a BGP protocol, and the like. When the technical scheme provided by the embodiment of the disclosure is implemented, the network equipment stores routing information of a plurality of gateway protocols. The routing information may include a prefix, a next hop, and an AS-path of the AS. After the network equipment acquires the routing information of the multiple gateway protocols, the routing information of the multiple gateway protocols is converted into target routing information of a preset gateway protocol, and the target routing information is sent to a preset routing storage server through the preset gateway protocol. And the route storage server receives the target route information sent by the network equipment through a preset gateway protocol.

In step S72, the destination route information is stored.

By applying the technical scheme shown in fig. 7, the network device stores all the routing information in the preset routing storage server through the preset gateway protocol. At this time, the route storage server may store all the route information of the entire network system. The query system can query the required routing information from the routing storage server, the query system only needs to be adapted to the routing storage server, and does not need to be adapted to the network equipment of each manufacturer independently, so that the expandability of the query system is improved, and the problem of poor expandability of the routing query system in the related technology is solved.

Fig. 8 is a flowchart illustrating another route storage method applied to a route storage server according to an exemplary embodiment, where the route storage method is applied to a route storage server, as shown in fig. 8, and step S71 in the method can be subdivided into step S711, which is described as follows.

In step S711, a first route update packet of a preset gateway protocol sent by the network device is received, where the first route update packet carries target route information.

In step S72, the destination route information is stored.

Fig. 9 is a flowchart illustrating another route storage method applied to a route storage server according to an exemplary embodiment, where as shown in fig. 9, the route storage method is applied to a route storage server, and step S72 in the method can be subdivided into steps S73 and 74, which are described as follows.

In step S72, the destination route information is stored.

In step S73, a second route update packet of a preset gateway protocol sent by the network device is received, where the second route update packet carries the first route information with the changed route attribute in the target route information and the route attribute after the change of the first route information.

In the embodiment of the present disclosure, the first attribute may be represented by update, and the second attribute may be represented by withdaw. The first attribute and the second attribute may also be represented by other characters, which are not specifically limited in this disclosure.

In step S74, the first routing information in the route storage server is updated according to the changed route attribute of the first routing information.

In one implementation, the route storage server may structurally store the target route information into a database. For example, the destination routing information in the database may include a prefix, a next hop, a status, and an as-path, as shown in table one.

Watch 1

Prefix	Next hop	Status of state	as-path
				1.1.1.1/32	1.1.1.2	1	/
1.1.1.2/32	1.1.1.2	1	/

In table one, each row represents a piece of routing information. The state is 1, which indicates that the piece of routing information is valid routing information; the state is 0, which indicates that the piece of routing information is invalid routing information.

The following describes a route update procedure provided in the embodiment of the present disclosure with reference to table one. Wherein the first attribute is represented by update and the second attribute is represented by withdraw.
