Abstract

The embodiment of the present invention discloses a method and device for triggering protection switching due to signal degradation of a link aggregation port, wherein the method includes: acquiring the member port status information of the link aggregation port from the status register of the link aggregation port; The member port status information of the link aggregation port is obtained to obtain the quantity value X of the signal degradation optical path attenuation in the member port of the link aggregation port; the quantity value X of the signal degradation optical path attenuation in the member port of the link aggregation port is compared with a predetermined threshold; When the number X of signal degradation optical path attenuation in the member ports of the link aggregation port is greater than the predetermined threshold, set the state of all member ports of the link aggregation port to the signal degradation state, and notify the virtual segment layer to report the fault and perform service protection switching On the backup link, the Ethernet service egress is realized when the SD optical failure occurs on the link aggregation port to realize the protection switching and switching back of the service, ensuring the switching performance of the carrier level.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for SD (Signal Degrade, signal degradation) triggered 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) lay...
