Problems solved by technology

[0019] In the existing method for realizing control channel binding, since the IPCC of the first node and the IPCC of the second node are bound through an interface, one IPCC of the first node can only bind one IPCC of the second node, Therefore, when the number of IPCCs increases, a large number of Hello messages need to be sent to refresh the IPCCs, which will easily cause message congestion on the network, making it impossible to refresh the IPCCs in time.

Embodiment Construction

[0092] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.

[0093] see figure 1 , the present invention proposes a method for realizing control channel binding, including:

[0094] Step 100, the first node sends a Config message to the second node.

[0095] In this step, when the first node supports multiple IPCC binding operations, the Config message may also include an IPCC identifier of the second node in addition to all the fields in Table 1.

[0096] When the first node does not support multiple IPCC binding operations, the Config message only includes all the fields in Table 1.

[0097] Step 101, the second n...

Abstract

The invention discloses a method and a device for achieving control channel binding. The method comprises steps that a first node sends a Config message to a second node, wherein the Config message comprises an IPCC identifier of the second node; and when the first node receives a ConfigAck message from the second node, the first node determines the IPCC identifier of the second node in the ConfigAck message is identical to the IPCC identifier of the second node in the Config message and then seconds a Hello message to the second node. As the Config message comprises the IPCC identifier of the second node, an IPCC of the first node can be bound with multiple IPCCs of the second node, so that only one Hello message is sent to achieve refreshing of the multiple IPCCs of the second node in the sending of the Hello message, thereby reducing the number of Hello messages to be sent, and ensuring real-time refreshing of IPCCs.

Description

technical field [0001] The invention relates to the field of data network communication, in particular to a method and device for realizing control channel binding. Background technique [0002] In the current Generalized Multi-protocol Label Switching (GMPLS, Generalized Multi-protocol Label Switching), Link Management Protocol (LMP, Link Management Protocol) is used to manage links between nodes and control channel management. [0003] The functions of LMP include control channel management, link attribute association, link connectivity verification and fault management. Among them, the first two items are used to manage traffic engineering (TE, Traffic Engineering), which are the core functions necessary for the link; the last two items are optional extension functions, which are used to cope with the separation of the control channel and the data channel. [0004] The management of the control channel is used to establish and maintain the connection of the IP control ch...
