Simulation of an Optical Packet Switch Scheduler

Projecte fet en col.laboració amb Univesità di BolognaThe last years, the importance of optical networks has increased considerably, not only for transport purposes but also for switching operations. Researchers have developed a lot of literature concerning this subject, and firms have started adding photonic links to the existent networks. The scientific community has realized the importance of optical switching, and many laboratories are developing optical burst/packet schedulers. But still many algorithms to resolve contention are being discussed, and many parameters are being studied. This thesis will discuss four different algorithms and few parameters by means of a new simulator of an optical scheduler. This simulator pretends to follow the structure of the latest scheduler designed at the University of Bologna in a modular way, and will provide clear results on loss probabilities in every case. Delay-oriented and gap-oriented scheduling policies will be studied, both with void filling strategies as well as without void filling
