Exchange Business Gmpls-based Optical Burst Access

In Optical Burst Switching, the granularity of bandwidth is between abandwidth of wavelength and a bandwidth that meets the need of agrouping transmitting, which is more efficient than that of OpticalCircuitry Switching and more practical than Grouping Optical Switching.That is to say OBS has the merits of Optical Circuitry Switching andGrouping Optical Switching, meanwhile OBS gets over some flaws ofthese two kind of Switching, thus we can say that the OBS is the bestchoice over the Optical Circuitry Switching and Grouping OpticalSwitching. Moreover GMPLS is the protocol system indicating thetendency of network intelligentization. Thus the paper's innovative pointis to combine the OBS with GMPLS because this kind of combination isthe inevitable tendency in future Optical Transmitting NET.Firstly, the paper analyzes the NET of OBS and GMPLS as well asthe merits and demerits in present researching achievements of LOBS,then compares the merits based on GMPLS and LOBS, at last presents thedetailed implement methods for marginal node of OBS based on GMPLSand some modifications for the protocol so as to fit our experimentalsystem.The followings are the main hardware realization and testing workin the project.●The implement of Gbit Ethernet's operation access: firstly to studythe 802.3 protocol and write out the implementing scheme using FPGAaccording to the demands of NET based on GMPLS and OBS, use Verilogto write out the program and make the circuit board to test my moduleafter discussing with tutor and other parters, then use Sniffer to send datato and receive data from FPGA, at last all parters test together to realize...
