THE OVERLAY NETWORK BASED ON DYNAMIC CIRCUIT USING VIRTUAL ROUTER

摘要

PURPOSE: Dynamic circuit-based overlay network setup method and structure using a virtual router are provided to maximize the applicability of existing network resources by forming various overlay networks based on the virtual router. CONSTITUTION: High-speed switches(110) are composed of a device with various transmission layers. A virtual router(111) operates and sets-up a routing table. A GMPLS-based controlling plane(120) controls the transmission planes of the switches. A path computation engine(PCE) block(130) efficiently calculates the path of the controlling plane. A management block is further prepared.
