| Summary: | 碩士 === 長庚大學 === 電機工程研究所 === 88 === Because Erbium-Doped Fiber Amplifier can efficiently improve Wavelength Division Multiplexing optical power problem, the dual-bus optical networks of non-regenerative (passive) node implementations have become attractive. In general, non-generative implementations are better than generative implementations at (1) media access (MAC) delay, (2)cost and (3)susceptibility of node failures, etc. Base on the WDM , the huge bandwidth of the optic-fiber can be several high-speed parallel channels with separate wavelengths. Due to number of wavelengths is limited some requests may share or reuse same wavelength to improve the network throughput. In this paper two protocols is propose to improve the network throughput, one is named The Synchronous Wavelength Sharing Protocol (SWSP) which only has wavelength sharing scheme; the other is add the wavelength reusing scheme named The Synchronous Wavelength Reusing/Sharing Protocol (SWRP). Simulation results show that for a limited number of wavelengths(8) and tunable receivers(2), the network throughput and MAC delay at SWRP of heavy traffic load is better than that of SWSP.
