LINE SWITCHING NETWORK

摘要

PROBLEM TO BE SOLVED: To relay a packet having a transmission control protocol-Internet protocol(TCP-IP) address via a synchronous transfer mode(STM) network. SOLUTION: Any of local switches LS-1, LS-2 that contains a destination terminal based on a TCP-IP address in a TCP-IP packet is identified, time slot switch information that is route information in an STM network up to the local switch is generated and a packet is transferred in the STM network according to the time slot switch information. In this case, when no idle time slot is in existence, the packet is temporarily stored till an idle slot is available.
