PURPOSE: A device of simulating an optical burst assembly for an optical burst switching network is provided to optimize burst size and burst assembling time when converging IP traffic in an optical packet edge router to assemble the IP traffic into one burst and passing the burst through an optical network, thereby improving service speed and service quality by advancing burstiness of the IP traffic. CONSTITUTION: An optical/electric converter(503) performs an optical/electric conversion process for a demultiplexed input optical frame of a wavelength demultiplexer(502). An optical frame disassembler(504) restores the converted optical frame to data, separates the data into plural individual packets, and distinguishes packet data from MPLS labels. A scheduler(509) inputs the MPLS labels to carry out an LIB lookup process, obtains new label information, and performs a scheduling process. An optical burst assembler(505) inputs the packet data to execute a burst assembling process, requests the scheduling process of the scheduler(509), and outputs an assembled burst. An electric switching unit(506) switches the outputted burst. An electric/optical converter(507) performs an electric/optical conversion process for the switched burst, and outputs the converted burst to a wavelength multiplexer(508). |
