Abstract

The embodiment of the invention discloses a method and a device for signal degradation trigger protection switching of a link aggregation port. The method comprises the steps of acquiring member port state information of the link aggregation port from a state register of the link aggregation port; acquiring a quantity value X of member ports, in which signal degradation optical path attenuation is generated, of the link aggregation port according to the acquired member port state information; comparing the quantity value X of the member ports, in which signal degradation optical path attenuation is generated, of the link aggregation port with a predetermined threshold value; and when the quantity value X of the member ports, in which signal degradation optical path attenuation is generated, of the link aggregation port is greater than the predetermined threshold value, setting all member ports of the link aggregation port to be a signal degradation state, and notifying a virtual segment layer to carry out fault reporting and service protection switching so as to switch to a backup link, thereby realizing protection switching and back switching of services when SD (signal degradation) occurs if an Ethernet service outlet is the link aggregation port, and ensuring the carrier-class switching performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for SD (Signal Degrade, signal degradation) triggering protection switching of a link aggregation port. Background technique [0002] PTN network refers to the packet transport network, which is based on packet switching and connection-oriented multi-service unified transport technology. (QoS) and perfect operation, management and maintenance (OAM) and other five basic attributes, and take into account the support of traditional time division multiplexing (TDM) and asynchronous transfer mode (ATM) services, inheriting the graphical interface of the Synchronous Digital Hierarchy (SDH) network management , end-to-end configuration and other management functions. [0003] The PTN network is divided into three layers, namely the PTN virtual channel (VC) layer network, the PTN virtual path (VP) layer network and the PTN virtual segment (VS) layer ne...
