Summary :

The DQDB MAC Protocol standardized by the IEEE 802.6 Committee is a single segment bandwidth reservation scheme that only reserves bandwidth for one segment in the distributed queue. Recently, multi-segment bandwidth reservation schemes that reserve bandwidth for not only one segment in the distributed queue but also a part of or all segments in the local node queue have been proposed. In this paper, we propose a new multi-segment bandwidth reservation protocol that can quickly react to changes in a node's traffic and can quickly allocate the bandwidth fairly and waste-free. We also evaluate the mean message transmission delay and throughput convergence performance by simulation. As a result, it is shown that the mean message transmission delay can be decreased and the throughput can be quickly converged to fair bandwidth allocation.
