Abstract
Optical burst switching (OBS) is a promising switching technology for next-generation
Internet backbone networks. One of the design challenges is how to provide fair bandwidth
allocation in OBS networks; the schemes proposed for general store-and-forward IP switching
networks can not be used because of the non-buffering and un-fully utilized bandwidth
characteristics of OBS networks. We propose a rate fairness preemption (RFP) scheme to achieve
approximately weighted max-min fair bandwidth allocation in OBS networks. We present an
analysis of the burst loss probability in RFP-based OBS networks. The analysis and simulation
results show that the RFP scheme provides fair bandwidth allocation in OBS networks.
