Title:
SYSTEM AND METHOD FOR DUPLEXING LINE INTERFACE
Document Type and Number:
Japanese Patent JP2003037616
Kind Code:
A
Abstract:
To provide a line interface duplexing system, which can easily deal with the line interface of 1:N as well by simplifying the management of a control program and remarkably shortening a switching time.
A representative sending port is registered on each of routing tables 21a-1 to 21a-N in IP address retrieval parts 21-1 to 21-N. Besides, a real sending port is determined out of the representative sending ports by referring to translation maps 22a-1 to 22a-N in sending port translating parts 22-1 to 22-N. Thus, when switching the line interface, without changing the routing tables 21a-1, to 21a-N and 61, switching can be performed only by changing the translation maps 22a-1 to 22a-N.
