Embodiment 1

[0092] The SDN control terminal establishes a connection with the routing / forwarding system equipment. Take the NETCONF connection as an example. After the connection is successfully established, the SDN control terminal sends routing and / or policy information to the routing / forwarding system equipment. Take rib routing as an example. Image 6 It is a flow of a method for establishing a connection between an SDN control terminal and a routing / forwarding system device according to an optional embodiment of the present invention Figure 1 ,Such as Image 6 As shown, the process includes the following steps:

[0093] Step S601, the SDN control terminal carries its own terminal identification ClientID and priority, and its own capability information, and initiates a hello request (NETCONF link establishment request) to the routing / forwarding system equipment;

[0094] Optionally, the hello message for the SDN control terminal to request link establishment is as follows:

Embodiment 2

[0109] The SDN control terminal establishes a connection with the routing / forwarding system equipment. Take the NETCONF connection as an example. After the connection is successfully established, the SDN control terminal requests the routing / forwarding system equipment to query the routing information issued by the terminal. Take the rib route as an example. Figure 7 It is a flow of a method for establishing a connection between an SDN control terminal and a routing / forwarding system device according to an optional embodiment of the present invention Figure II ,Such as Figure 7 As shown, the process includes the following steps:

[0110] Step S701, the SDN control terminal carries its own terminal identification ClientID and priority, and its own capability information, and initiates a hello request (NETCONF link establishment request) to the routing / forwarding system equipment;

[0111] Step S702, the routing / forwarding system equipment receives the hello message sent by ...

no. 3 example

[0133] The SDN control terminal establishes a link with the routing / forwarding system equipment. Take the NETCONF connection as an example. After the connection is successfully established, it actively disconnects, and modifies the priority of the terminal, and reconnects with the routing / forwarding system equipment with the new priority. establish connection. Figure 8 It is a flow of a method for establishing a connection between an SDN control terminal and a routing / forwarding system device according to an optional embodiment of the present invention Figure three ,like Figure 8 As shown, the process includes the following steps:

[0134] Step S801, the SDN control terminal carries its own terminal identification ClientID and priority, and its own capability information, and initiates a hello request (NETCONF link establishment request) to the routing / forwarding system equipment;

[0135] Step S802, the routing / forwarding system equipment receives the hello message sent ...

Abstract

The present invention provides a method and device for processing routing status and / or policy information, wherein the method includes: the routing / forwarding system receives a first request for establishing a connection sent by a software-defined network SDN control terminal, wherein the first The request carries the identification of the SDN control terminal; the routing / forwarding system establishes the corresponding relationship between the routing status and / or policy information sent by the SDN controlling terminal and the identification; the routing / forwarding system manages the routing status and / or policy information according to the corresponding relationship . The present invention solves the problem of not distinguishing the home control terminal of routing state and / or policy information in the related art, and realizes accurate management of routing state and / or policy information.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing routing state and / or policy information. Background technique [0002] As the current network exposes more and more disadvantages and people's demand for network performance is getting higher and higher, researchers have to add many complex functions to the architecture of routers, such as Open Shortest Path First (Open Shortest Path First) Path First, referred to as OSPF), Border Gateway Protocol (Border Gateway Protocol, referred to as BGP), multicast, differentiated services, traffic engineering, network address translation (Network Address Translation, referred to as NAT), firewall, multi-protocol label switching (Multi Protocol Label Switching, referred to as MPLS), etc., which makes switching devices such as routers more and more bloated and the space for performance improvement is getting smaller and smaller. [0003] However, quite dif...
