Cost-based burst dropping strategy in optical burst switching networks [PDF]
, 2005 Optical burst switching (OBS) is a new paradigm for future all-optical networks. Intentional burst dropping is one of techniques used to achieve desired quality of service. In this paper we note that some bursts are more likely to cause contention.
