Tree-based batching and serialization of overlapping bursts to reduce losses in OBS networks

In the recent past, the bandwidth demand in the Internet is increasing phenomenally, due to rising of multimedia and Internet related applications such as video conferencing, IPTV and audio and video streaming. In order to meet these growing demands Optical Burst Switching (OBS) is the promising switching technology from Wavelength Division Multiplexing (WDM) networks. In this paper, we propose a tree-based batching with serialization to improve the efficiency. Experimentation through simulations on NFSNET shows the significant improvisation in the percentage of burst loss and channel utilization in the network.
