| Abstract: | The basic architecture of optical burst switching network core switch node is briefly presented in this paper. The function of switch control module and the structure of core switch node are introduced in brief. Constructing the simulation platform of OBS system is presented. This paper introduces the function of main modules in OBS system, the key technologies involved and the parameters which can be configured. Several structures of OBS core switch node simulation module are built in this paper. Simulation results and analysis of the network performance are also presented. This paper analysis the impaction of burst lost ratio by using different switching structures. |
