Abstract

The invention provides a method of building a control channel, a forwarding point (FP) and a controller. The method comprises that a first FP sends the topological information of the first FP to a second FP through a link layer discovery protocol (LLDP), so that the second FP can send the topological information of the first FP to the controller through a first control channel after the second FP receives the topological information of the first FP. The first FP receives first routing information sent by the controller that the first FP reaches the controller, and the first routing information is generated by the controller according to the topological information of the first FP. The first FP builds a second control channel with the controller according to the first routing information. The first FP does not need to run an interior gateway protocol (IGP), the fact that the first FP maintaining the neighbourship of the IGP is avoided, and the first FP does not need to store the routing information of other FPs reach a virtual cluster, the storage resource of the first FP is beneficial to be saved, and the forwarding performance of the first FP is beneficial to be improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method for establishing a control channel, a forwarding device and a control device. Background technique [0002] The virtual cluster system consists of a control device (Controller) and a forwarding device (Forwarding Point, FP). The control device is used to centrally control the FP in the virtual cluster, and the FP is used to forward the external packets of the virtual cluster. A control channel needs to be established for message transmission within the virtual cluster. In the prior art, a routing connection is established between the control device and the FP by running an Interior Gateway Protocol (IGP), and the FP establishes a control channel with the control device through the routing connection. Since there may be multiple FPs in the virtual cluster , which requires the establishment of IGP neighbor relationships between FPs and between FPs and control devices. I...
