Route control system and route control method in a switching apparatus

Abstract

A system includes a cell handler, a virtual path handler, a virtual channel handler, a trunk. and a controller. The controller initiates, based on issuing an instruction to the cell handler, a loop-back control test. The loop-back control test involving transmission of an operation and maintenance (OAM) cell from the cell handler, via the virtual path handler, the virtual channel handler, and the trunk, and back to the cell handler. The controller further monitors the OAM cell, detects a fault based on monitoring the OAM cell; and perform fault avoidance based on detecting the fault.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a route monitor control system which monitors an ATM (Asynchronous Transfer Mode) switching apparatus, and a route monitor control method.[0003]2. Description of the Related Art[0004]In recent years, a variety of services supported by an ATM switching apparatus are required in rapid spreading of a market of the ATM switching apparatus. Therefore, various types of hardware is installed into the ATM switching apparatus to provide the variety of services and a service function of each type of hardware is extended.[0005]On the other hand, in the quality verification of these hardware functions, after a maintenance person recognizes a kind of hardware to be verified, a maintenance command is given to carry out a conductiveness test between a trunk and a node by a monitoring apparatus installed in or out of the system.[0006]However, because a managing method is different for every system in su...

AI Technical Summary

Benefits of technology

The present invention provides a route monitor control system and method that allows for efficient maintenance operation without the need for specialized knowledge. The system includes an OAM cell handler, virtual path handler, virtual channel handler, trunk, and control unit. The control unit sends an OAM cell send instruction to the specific OAM cell handler, carries out a loop back control to the virtual path handler, virtual channel handler, and trunk, and determines the fault position based on the returning or non-returning of the OAM cell from the object unit. The control unit may also carry out a switching operation of the route from the virtual path handler to the trunk for fault avoidance. The technical effect of the invention is to simplify the operation and maintenance of monitoring apparatuses and facilitate fault avoidance.

Problems solved by technology

However, because a managing method is different for every system in such a conventional route monitor control system, there is a problem to need professional knowledge for maintenance operation for every system.
