Embodiment Construction

[0032] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] Functional Overview

[0034] The main idea of ​​the present invention is: when a physical link in the link aggregation group fails, the bandwidth of the intact physical link in the aggregated link cannot meet the actual business needs of the user, and the failed physical link If the physical link is on the active link, the slave port of the active link is released, so that the data in the service VLAN is reconnected, thereby ensuring that the bandwidth provided on the Ethernet ring network can meet the user's bandwidth requirements.

Abstract

The invention discloses a protection method used for the link aggregation group of an Ethernet ring network and a device thereof; wherein, the method comprises the steps as follows: the state of the physical link in the link aggregation group is detected; when the failure state of certain physical link in the link aggregation group exists, the current wideband of the aggregation link group is compared with the inverse threshold value which meets the practical service requirement; furthermore, according to the comparison result, the subsequent processing is carried out; the protection method and the device thereof can meet the wideband requirement of the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for protecting a link aggregation group of an Ethernet ring network. Background technique [0002] The Ethernet ring protection system in RFC3619 includes a plurality of nodes connected to form a ring, and multiple domains, ie, Ethernet ring protection domains, can be defined on the ring. [0003] An Ethernet ring protection domain may include a master node (MASTER), several transfer nodes (TRANSIT), and a group of protected business virtual local area networks (Virtual Local Area Network, referred to as VLAN) for user data forwarding. Wherein, two ports of the master node on the ring are respectively defined as a master port and a slave port, and the protected service VLAN is defined as a protection service VLAN. When the link on the ring is intact, the master node blocks the protection service VLAN forwarding function of the slave port, and there is no loo...
