Embodiment Construction

[0030] In order to make the technical solution of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments. 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.

[0031] The present invention provides a method for optimizing LACP protocol link aggregation based on Ethernet link level OAM, including:

[0032] Step S1: The ports in the aggregation group use the LACP protocol to establish an aggregation link.

[0033] In actual implementation, the physical ports in the aggregation group automatically run the LACP protocol, and negotiate between the local port and the peer port by sending LACP packets: the end with the smaller device ID (system priority + system MAC address) is selected If it is considered excellent, select the port with the smaller port ID (port prior...

Abstract

The invention provides an LACP (link aggregation control protocol) link aggregation optimization method based on Ethernet link-level OAM (operation, administration and maintenance). The method comprises the steps of building an aggregation link by a port in an aggregation group according to an LACP; automatically executing an OAM protocol on two ports of a work link in the aggregation link after creating a business, and monitoring the performance of the work link; and if the performance of the work link is monitored to be lower than a set performance standard, stopping aggregation of the work link, and rebuilding an aggregation link according to the LACP. According to the method disclosed by the invention, the aggregation link of the LACP is optimized and monitored through the OAM link, so that the aggregation link can be rebuilt according to the performance index of the link, and business transmission with higher quality is achieved under the condition of pursuing bandwidth.

Description

technical field [0001] The present invention relates to the technical field of data communication and transmission, and more specifically, to a method and device for optimizing LACP link aggregation based on Ethernet link level operation, administration and maintenance (OAM). Background technique [0002] Link aggregation is to aggregate multiple physical Ethernet ports together to form a logical aggregation group. The upper layer entity using the link aggregation service regards multiple physical links in the same aggregation group as a logical link, adding link bandwidth, and load sharing can be performed among member ports in the aggregation group to improve link reliability. Link aggregation can be divided into three types according to the aggregation method: manual aggregation, static aggregation and dynamic aggregation. LACP (Link Aggregation Control Protocol, Link Aggregation Control Protocol) based on the IEEE802.3ad standard is a method for realizing dynamic link ag...
