LOAD-DISTRIBUTED COMMUNICATION NETWORK, SUBSCRIBER USER ACCOMMODATION NODE, AND NETWORK CONTROL SERVER

摘要

PROBLEM TO BE SOLVED: To attain a load-distributed communication network capable of obtaining a high reliability in a data communication between subscriber users.

SOLUTION: At subscriber user accommodation nodes 1 to 4, the number of transfer frames outputted to each transfer path in every unit time is observed and when the number of transfer frames exceeds a threshold on an arbitrary transfer path, a transfer table is controlled to allocates a path identifier other than the path identifier of the transfer path to an arbitrary entry of the address of a destination user using the transfer path.
