The Seventh International Workshop on Optical Networking Technologies: Examining the Case for Optical Burst Switching
Monday 27 November, 9:00 – 12:00
Dr. Tarek El-Bawab, Jackson State University
|Optical Burst Switching (OBS) introduces a new method of switching at the granularity of optical data bursts. This is a granularity between optical circuits, which are whole-sale large-bandwidth lightpaths, and optical packets, which are small data units that are difficult to buffer, process, and route using today’s optical technologies. As such, OBS has the potential to enhance bandwidth efficiency and cost effectiveness in transport networks, and can circumvent some technological barriers facing optical packet switching. OBS has attracted a lot of interest among several research groups and become a popular topic of study worldwide. Several equipment vendors have also looked at OBS thoroughly. Many in the optical networking community consider this technology enthusiastically, and have adopted the case for OBS. |
A lot of OBS research efforts however are confined to network simulations, and assume green-field or hypothetical scenarios. In practice, several architectural, technological, and economic issues are involved in the OBS proposal. OBS requires dynamic capability to rapidly allocate optical wavelengths to data bursts, and to rapidly release them after burst transmission. It requires advanced burst assembly strategies, scheduling algorithms, signaling, and control schemes. Progress in some optical component technologies is desirable, and may be required. Many professionals see difficulties in designing high-performance OBS networks that can satisfy all these requirements while achieving robustness, reliability, simplicity, and economics. Some are concerned about how a new OBS-based transport layer would fit into existing network architectures, and how it would work with IP/TCP, SONET/SDH, and other existing layers.
In this workshop, we discuss the case for OBS. We consider the potential of OBS deployment in practical networking applications. Contributions in all areas of OBS research and strategy are solicited. Focus on practicality, implementation, deployment, and economic issues; and capturing the theme of this workshop are required for any proposal to be accepted. Electronic submission of proposals for participation (an abstract and participants’ bios) are invited no later than August 7, 2006. Notification of acceptance will be sent around September 4, 2006. Final submissions, which will be due on October 9, 2006, will comprise:
1. Short paper (or extended abstract), Globecom style, no more than 2-3 pages,
2. Power point presentation slides of the paper/talk, and
3. Presenter’s bio.
Proposals/submissions are to be addressed to email@example.com, or firstname.lastname@example.org.
