Serial homologous mechanism based fault notification device and method therefor

Abstract

The invention provides a notification device and a method of an ASON fault, which are based on a serial homologous mechanism. The system includes a processing module of a fault message, a connection and storage module of the fault, a filtering module of a homologous connection, a parameter control module of serial time and a sending module of the fault message, which are connected orderly. The processing module of the fault message is used to process the fault message in an automatically switched optical network. The connection and storage module of the fault is used to store the connection message influenced by the fault. The filtering module of the homologous connection filters the records which have the same source node from the connection message stored in the connection and storage module of the fault and makes the sending module of the fault message send the fault notification message corresponding to the source node. The parameter control module of a serial time adjusts the delay dynamically when the sending module of the fault message sends each fault notification message. The invention can reduce the fault notification times and improves the success ratio of restoring the path building in addition to slowing down the decline of the restoration ratio, which is brought by the resource reservation collision.

Description

technical field [0001] The invention relates to a fault notification device and method using a serial homologous mechanism applied in an Automatically Switched Optical Network (ASON: Automatically Switched Optical Network), and belongs to the field of optical network communication. Background technique [0002] ASON is a new generation of optical network with automatic switching function. Its most prominent feature is the introduction of an independent intelligent control plane in the optical transport network, which relies on standardized signaling to achieve network control, and can automatically complete the establishment, modification, maintenance, removal and fault recovery of service paths, thus realizing Functions such as dynamic service provision, bandwidth allocation and intelligent survivability mechanism. Therefore, ASON is widely regarded as the mainstream technology of the next generation network (NGN). [0003] Fault recovery rate and fault recovery time are ...
