METHOD FOR PERFORMING TRAFFIC ENGINEERING BY USING SIMULATION AND OPTIMIZATION IN MULTI-PROTOCOL LABEL SWITCHING NETWORK, AND SERVER THEREFOR

摘要

PURPOSE: A method for performing TE(Traffic Engineering) by using simulation and optimization in multi-protocol label switching network, and a server therefor are provided to allow a network manager to effectively devise TE policy. CONSTITUTION: An input processor(31) receives every value inputted by a user. A router interface(32) obtains every data obtained from switches. A simulation logic(33) is a part where simulation techniques are actually implemented. An optimization logic(34) is a part where optimization techniques are actually implemented. A data manager(35) stores and loads every input and output data used for simulation and optimization and their meta data. A result output unit(36) reports the simulation and optimization result to a manager by a report or through a GUI(Graphical User Interface). A result application unit(37) generates a substantial TE command, applies it to a network and checks its result, in automatically reflecting the simulation and optimization result in the network through a server.
