Communication system, communication path establishing method and management server

摘要

In interworking systems that utilize IP/MPLS protocol processing to operate a centralized control server within a MPLS-TP network as a pseudo-router unit; a system improves the utilization rate of the MPLS-TP network by establishing default paths beforehand as a precondition to coupling between MPLS-TP network edge devices and mapping a plurality of IP/MPLS paths between the same edge devices to the common default paths when mapping to provide IP/MPLS network connectivity.
