A framework to support IP over WDM using Optical Burst Switching

Optical burst switching (OBS) has been proposed as a switching technique to exploit enormous amount of capacity provided by wavelength division multiplexing (WDM) transmission technology. In this paper, we consider a model for overlaying IP network over the OBS WDM transmission backbone. In the framework of this model, the functional requirements of the interface between the IP layer and the OBS WDM layer are pointed out. Aimed at achieving some of these functionalities, we propose a scheme to set the \o set," an important system parameter for OBS, between the successive data bursts and their control packets. It is based on the systematic randomization of the time instances of releasing data bursts into the optical network to provide a reliable transport service to IP layer by keeping a low value of burst blocking probability. The role of this scheme in improving the performance of OBS is demonstrated via simulations for the case of TCP/IP traÆc.
