Abstract
In this paper we present the efficient burst reservation protocol (EBRP) suitable
for bufferless optical burst switching (OBS) networks. The EBRP protocol is a two-way
reservation scheme that employs timed and in-advance reservation of resources. In the
EBRP protocol timed reservations are relaxed, introducing a reservation time duration
parameter that is negotiated during call setup phase. This feature allows bursts to
reserve resources beyond their actual size to increase their successful forwarding
probability and can be used to provide quality-of-service (QoS) differentiation. The
EBRP protocol is suitable for OBS networks and can guarantee a low blocking probability
for bursts that can tolerate the round-trip delay associated with the two-way
reservation. We present the main features of the proposed protocol and describe in
detail the timing considerations regarding the call setup phase and the actual
reservation process. Furthermore, we show evaluation results and compare the EBRP
performance against two other typical reservation schemes, a tell-and-wait and a
tell-and-go (just-enough-time) like protocol. EBRP has been developed for the control
plane of the IST-LASAGNE project.
