Problems solved by technology

[0004] However, when there are many forwarding nodes at the edge of the virtual cluster, an IGP neighbor relationship needs to be established between every two forwarding nodes, which puts great pressure on the controller. Moreover, when there are many BGP RR nodes, the edge FP and each BGP RR Nodes also need to establish IGP neighbor relationships, which will further increase the pressure on the controller
In addition, the establishment of IGP neighbor relationship requires information exchange between nodes, which will affect the release speed of link status
It can be seen that the existing FA link state release method has the disadvantages of high pressure on the controller and slow release speed

Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0050] The embodiment of the present invention provides a publishing method for forwarding adjacent links, the flow chart is as follows figure 2 shown, including:

[0051] 101. The first logical node receives the node information of the second edge forwarding node sent by the node management module of the controller in the virtual cluster. Wherein, the first logical node is a logical node corresponding to the first edge forwarding node on the controller, and the ...

Abstract

The invention discloses a publishing method for forwarding adjacent links, which is applied to a virtual cluster, and includes: a first logical node receiving node information of a second edge forwarding node sent by a node management module of a controller in a virtual cluster; The logical node generates a logical link between the first edge forwarding node and the second edge forwarding node according to the node information of the second edge forwarding node; the first logical node generates the logical link between the first edge forwarding node and the second edge forwarding node The logical link is added to the IGP protocol message link state broadcast LSA / link state protocol data unit LSP; the first logical node publishes the link between the first edge forwarding node and the second edge forwarding node through the IGP protocol message LSA / LSP logical link. The method of the invention does not need to establish an IGP neighbor relationship between two nodes in the virtual cluster, can reduce the pressure of the virtual cluster system, and increase the release speed of link state information.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a publishing method for forwarding adjacent links. Background technique [0002] Such as figure 1 As shown, the virtual cluster includes a controller for controlling information transmission, internal nodes and edge forwarding nodes for forwarding information, the edge forwarding nodes are logically connected through vFabric, and the Border Gateway Protocol (Border Gateway Protocol) on the edge forwarding nodes and the controller Gateway Protocol, BGP) route reflector (Route Reflector, RR) nodes are connected through virtual generic routing encapsulation (Virtual Generic Routing Encapsulation, vGRE). Devices outside the virtual cluster need to transmit information through the virtual cluster. The information transmission process includes: the edge forwarding node FP1 receives the protocol packet sent by the device outside the cluster, and transparently transmits the proto...
