Embodiment Construction

[0014] In the embodiment of the present invention, by extending the intermediate system to intermediate system (Intermediate System to Intermediate System, IS-IS) protocol, the MPLS-TP network node can collect the LAG link information in the MPLS-TP network through the IS-IS protocol message , to manage the LAG link information.

[0015] IS-IS protocol is a Layer 2-based network protocol used for network topology discovery, network resource information collection, and data forwarding path calculation. IS-IS protocol has good scalability. IETF expands on the basis of IS-IS (ISO 9542) protocol to support IP layer network topology discovery, network resource information collection, and IP shortest path tree calculation. The IS-IS protocol includes three protocol packets:

[0016] 1) Hello message, used to discover neighbor nodes;

[0017] 2) Link State Packet (Link State Packet, LSP) message, used for exchanging link state information;

[0018] 3) A sequence number packet (Seq...

Abstract

The embodiment of the invention discloses an information management method of a link aggregation group (LAG), comprising the following steps: creating intermediate system-to-intermediate system (IS-IS) link state packet (LSP) messages containing LAG attribute information at a first network node and transmitting the messages to other nodes in a network; receiving a node of the IS-IS LSP messages containing LAG attribute information, and recording the LAG attribute information in the messages. The embodiment also discloses a network node. The embodiment can realize the management of the LAG attribute information.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method for managing link aggregation group information and a network node. Background technique [0002] MPLS (Multi-protocol label switch, multi-protocol label switching) was originally designed to improve forwarding efficiency. MPLS uses short, fixed-length labels instead of IP packet headers as the basis for forwarding, which improves forwarding efficiency compared with traditional IP routing. MPLS adopts the connectionless control plane to complete the establishment of LSP (label switch path, label forwarding path), and completes the data transmission through the connection-oriented LSP. [0003] LAG (link aggregation group, link aggregation group) is a link attribute that binds multiple physical links into one logical link, so that there are multiple links between two devices for data transmission. Flexible bandwidth expansion, fast link protection and load bal...
