Implementation of a hybrid burst contention resolution algorithm for optical burst switching networks

Optical burst switching is one of the optical switching technologies beside optical circuit and optical packet switching. It is considered as the optical switching paradigm that can be used in the near future before the technology that will support optical packet switching becomes mature. Optical bu...

Optical burst switching has many good features. However, issue specifically burst contention which results in burst loss still become unresolved issue. A major component in optical burst switched networks is the core node whose main functions are burst scheduling and contention resolution. As traffic on the network increases, the contention at the core nodes also increases. This usually leads to burst drop at the core node if no suitable contention resolution technique is used.

Wavelength conversion will always be the first technique to be invoked in order to resolve contention whenever it occurs.
