BHP saving mechanisms — An approach to improve performance of Optical Burst Switched network

Abstract

To cope up with high speed demands of internet traffic, Optical Networks seems to be optimistic solution for Next Generation High Speed Network. An Optical Burst Switching (OBS) technology of Wavelength Division Multiplexing (WDM) has proved itself to satisfy current demands of the internet traffic. In OBS network, key concern is to reduce burst dropping probability and it is depend on different factors like burst size, offset time and scheduling algorithms used to schedule the bursts. It is observed that the burst dropping probability is directly proportional to number of Burst Header Packets (BHPs) dropped in an OBS network. This paper introduced the increase in control channel approach to control BHP dropping probability with the help of extensive simulation on NS2. Simulation result shows that the dropping probability decreases with increase in number of control channel.
