Embodiment Construction

[0033] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] This embodiment provides a tunnel load sharing method, such as figure 1 As shown, the tunnel load sharing method includes steps S102 to S104.

[0035] Step S102: The network node detects the alarm condition of the tunnel, and updates the information of the effective tunnel in the current tunnel load sharing group information, wherein the tunnel load sharing group information is sent to the network node by the platform protocol module.

[0036] Step S104: the network node sends the updated valid tunnel information to the forwarding chip in the network node, wherein the forwarding chip selects the valid tunnel according to the information to perform load balancing on the service traffic.

Abstract

The present invention provides a tunnel load sharing method and device, wherein the method includes: a network node detects an alarm condition of a tunnel, and updates the information of valid tunnels in the current tunnel load sharing group information, wherein the tunnel load sharing group information is Sent by the platform protocol module to the network node; the network node sends the updated information of the valid tunnel to the forwarding chip in the network node, wherein the forwarding chip selects the valid tunnel according to the information to load balance the service traffic. The invention solves the problem of slow service convergence speed in the related art when the tunnel in the tunnel load sharing group has forwarding failure, thereby realizing the fast convergence of the service and improving the forwarding performance of the network node.

Description

technical field [0001] The present invention relates to the communication field, in particular to a tunnel load sharing method and device. Background technique [0002] In the field of computer data communications, especially in data bearer networks, tunneling technology is widely used, and load sharing is a strategy and method for balancing loads on multiple links on network node devices. When the packet packet processing node finds that the forwarded packet can be forwarded through multiple paths, how to reasonably select a path so that the network node can achieve higher forwarding performance or meet certain forwarding requirements is the requirement of load sharing. solved problem. The tunnel load sharing referred to in this application refers to a strategy and method for load balancing service traffic on multiple tunnels on a network node device. [0003] There are currently two ways to form a tunnel load sharing group. One is to form multiple tunnel exits calculated...
