Abstract: The field of networking has experienced growth at a tremendous rate over the last decade. The popularity of the Internet is soaring as more people gain an increased awareness of the vast amounts of information available at the click of a button. This growing demand is leading to many new opportunities in networking, as people demand faster and better applications and services, such as World Wide Web browsing, video-on-demand and interactive television. The rapid expansion of the Internet and the ever-increasing demand for multimedia information are severely testing the limits of our current computer and telecommunication networks. There is an immediate need for the development of new high-capacity networks that are capable of supporting these growing bandwidth requirements. We need to be able to scale current networks to support the increasing volumes of information. Optical networks are a logical choice to meet the future communication demands, with optical fiber links offering huge bandwidth. Thus, optical burst switching (OBS) is considered as a suitable transport methodology for the realization of optical core networks due to the balance it offers between coarse-grained optical circuit switching (OCS) and fine-grained optical packet switching (OPS). OBS avoids the use of optical buffering and optical processing logic unlike in OPS but still achieves switching in optical domain. It improves the utilization of the fiber compared to OCS because of statistical multiplexing of bursts on different wavelengths. Although, optical burst switching appears to offer advantages over optical circuit switching and optical packet switching, several issues need to be considered before optical burst switching can be deployed in transport networks.
