DUPLICATION CONTROL METHOD OF LINKING ASSEMBLY BETWEEN NODE AND NODE OF ATM COMMUNICATION NETWORK SWITCHNG SYSTEM

摘要

The present invention configures a connection structure between nodes mounted in an exchange system that performs a distributed exchange function so that an ATM matching function and an ATM user can communicate with each other in a redundant structure, and automatically controls the ATM-MSS. The present invention relates to a node-to-node connection assembly (NIA) redundancy control method of an asynchronous transmission mode information communication network switching system (ATM-MSS) that improves the reliability and stability of a node. When an error occurs, it detects it and transfers the active node-to-node connection assembly to the standby state of the node-to-node connection assembly, so that it can be operated instead, thereby providing continuous service support to the subscriber, thereby improving the stability and reliability of the system.
