Abstract:The paper discusses the structure of the network based on LOBS-HC (labeled optical burst switching with home circuits), a newly proposed optical switching technology that can provide bandwidth guarantee and increase the utilization of wavelength bandwidth. Based on Visual C++, we design and implement a LOBS-HC based network simulation platform with some core processes, such as traffic flow generation and convergence, burst assembly, and logical HC link establishment and release. Finally, the performance of the LOBS-HC based network is evaluated in terms of throughput, delay, wavelength utilization etc. The simulation results show that LOBS-HC-based network achieves higher bandwidth utilization than the network based on OCS (optical circuit switching) with the same bandwidth guarantee.
