| Optical burst switching (OBS) provides a promising solution for utilizing the huge terahertz bandwidth of optical wavelength division multiplexing (WDM) transmission technology. To exploit this bandwidth, several reservation schemes have been proposed, which include just-in-time (JIT) signaling, just-enough-time (JET) signaling and burst segmentation (BS).; Although some research works have been reported to analyze the performance of the OBS network using JIT and JET, due to the constantly changing nature of these schemes, a detailed performance evaluation involving JIT, JET and BS is essential for practical system design. Accordingly, in this thesis, we have analyzed and compared the performance of these schemes under various scenarios such as network size, delay variation and load variation in a OBS network. The contributions of this thesis include: (i) a detailed analytical model of the BS scheme; (ii) comparative analysis of JIT, JET and BS schemes; (iii) performance analysis of the network under various load conditions, and under various switching delays. Our findings show that the BS yields better performance than the JIT and JET schemes. The results obtained in this thesis are expected to lead to further performance improvements in OBS networks using the BS scheme. |
