This paper proposes a new optical burst switching (OBS) paradigm known as dynamic two-way reservation OBS (DTWR/OBS), in which the burst length is dynamically determined at an ingress router, according to the minimum length reservation period available on each wavelength channel within a lightpath, from the ingress router to the egress router. The dynamic nature of DTWR/OBS ensures the packet transmission rate is controlled at the ingress routers, based on the level of network congestion. This increases network utilization and eliminates burst blocking due to wavelength contention. An analytical model for a single isolated optical cross-connect (OXC) is derived to determine the waiting time distribution of an arbitrary IP packet at the ingress router using the proposed DTWR/OBS. The accuracy of the analytical model is confirmed by simulations.
