Embodiment Construction

[0020] The preferred implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] refer to figure 1 shown, as figure 1 It is a flow chart of the method for fast switching of link aggregation group channels in the first embodiment, and the method for fast switching of link aggregation group channels is introduced in detail in the embodiment of the present invention. The methods include:

[0022] S101: In the initial state, the port status bits in the link aggregation group are all set to up, and each port in the link aggregation group sends a CCM message to its peer port, and according to the received CCM message Calculate the port status within a unit time period;

[0023] Specifically, there are many nodes in the MPLS network, such as MEP, each node has multiple physical ports, a group of physical ports are bundled together to form a logical port, and a link is established between two nodes through...

Abstract

The invention discloses a quick switch method and a quick switch device of a link aggregation group channel. The quick switch method of the link aggregation group channel includes: under an initial state, setting status of ports in the link aggregation group channel as up status, enabling each port in the link aggregation group channel to send a CCM (continuous conduction mode) message to the port at the opposite end of each port, and calculating the port status in each unit time period according to the received CCM message; selecting a main port according to the port status in each unit time period, sending an LOC (loss of continuity check) alarm when the main port breaks down, and when the up status exists in a maintained port status bit, eliminating the LOC alarm; changing the status bite of the main port from the up status into down status, and switching the main port onto a high priority port having the up status. When the interior of the port channel is switched, only few link random loss problems exist. In a protection mechanism of MPLS (multiple protocol label switching), switching of a backup link is enabled to achieve a small amount of link random loss due to the fact that reporting of the LOC alarm can be rapidly judged out.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for fast channel switching of a link aggregation group. Background technique [0002] In the prior art, the OAM (Operations, Administration And Maintenance, operation, maintenance and management) message of the MPLS (Multi-Protocol Label Switching, multi-protocol label switching) network is carried in the main port of the port channel, and the CCM ( The Continuity Check Message (Continuity Check Message) message is used to detect the connectivity between the local MEP (Maintenance Association End Point, Maintenance Association End Point) and the remote MEP. At the same time, LACP (Link Aggregation Control Protocol, Link Aggregation Control Protocol) messages are also carried on the main port of the port channel. [0003] A LOC (Lost of Continuity Check, loss of continuity test) alarm will be issued when each physical port fails. Then the speed ...
