Paper Abstract

Considering the state of the art of wavelength conversion technology, it is likely to dictate a more limited and sparse deployment of wavelength converters in the optical burst switching (OBS) networks. Without wavelength conversion capabilities at optical switches, the start wavelength selection method becomes an important issue to avoid burst contention. We present a new start wavelength selection method, the minimum relative group combined interference level (Min-RGCIL) algorithm, which is a modified version of a proposed method called first-fit-TE (traffic engineering). The performance study indicates that the new method achieves better performance than the original one and is robust under Poisson and self-similar traffic.
