1. E. Sirén, Optical Packet Switching, Master's thesis, Helsinki University of Technology, 2002 (bib)

   Abstract: In this thesis recent research in the area of optical packet switching is reviewed, the main problems in the area are identied and a possible solution to some of the problems, optical burst switching, is studied in more detail. Optical burst switching and the JET protocol are studied by means of a simulation program specially built for this purpose. Optical packet networks are networks, where the switching operations are performed optically, and the data remains in optical domain through the transmission. There have already been several implementations of optical packet switching in laboratory environment, but commercial solutions are not expected within a few next years. This is due to the infancy of optical devices. Although the networks and the components have developed rapidly, there are still many unsolved questions. The main problems at the moment are the lack of optical random access memory and very high switching rates needed. A few solutions that try to overcome these er the benets of optical packet switching, have been proposed. One interesting alternative is optical burst switching. In the empirical part of the thesis the use of the JET protocol in optical burst switching network was studied. In contrast to earlier research, in this work the performance of JET protocol was studied in networks without wavelength conversion. As a result it was found that with relatively small buffers a performance that is comparable to that of a wavelength converted version can be achieved.
