Method for implementing redundant structure of ATCA (advanced telecom computing architecture) system via base interface and the ATCA system for use in the same

摘要

A method for implementing a redundant structure of an ATCA system via a base interface of a network system based on an ATCA standard, and the ATCA system for use in the same are disclosed. Each of routing protocol shelves and LI shelves includes two ports connected to two IPC paths provided from the base interface, such that a representative IP address is assigned to a single port to be used, performs IPC communication using the representative IP address. If a port error or link-down state occurs, the representative IP address is assigned to the other port, resulting in the implementation of stable IPC communication. If the port error or link-down state occurs in an active-mode ShMC shelf, an IPC path passing through a standby-mode ShMC shelf is provided.
