/ SEGMENT AIS/RDI PROCESSING TMTHOD IN ATM NETWORKS

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a method for processing a segment alarm indication signal / remote fault indication cell.;2. The technical problem to be solved by the invention;It is an object of the present invention to provide a method for processing a simple segment alarm indication signal (AIS) / remote fault indication (RDI) cell that can distinguish whether a fault has occurred outside or inside a segment.;3. Summary of Solution to Invention;The present invention includes a first step of designating a role of nodes through which an asynchronous transfer mode (ATM) connection is passed through a communication management network (TMN); If a failure occurs on the link, determining a role of the node that discovered the failure; A third step of periodically transmitting the segment alarm indication signal (AIS) cell and the end-to-end alarm indication signal (AIS) cell periodically at a predetermined interval when the connection point is determined as the determination result of the second step; A fourth step of periodically transmitting an end-to-end alarm indication signal (AIS) cell in the forward direction periodically at the predetermined interval as a result of the determination of the second step; As a result of the determination of the second step, if it is a segment end point, the end-to-end alarm indication signal (AIS) cell is periodically transmitted in the forward direction at the predetermined interval, and the segment remote fault indication (RDI) cell is periodically reversed at the predetermined interval. Transmitting to the fifth step; And a sixth step of processing the segment alert indication signal (AIS) cell according to the role of the node when the segment alert indication signal (AIS) cell arrives.;4. Important uses of the invention;The present invention is used for asynchronous transfer mode (ATM) matching device.
