This paper discribes a shared medium access control protocol for residential home and small business customer ATM network application with distributed high-speed multimedia services. This protocol offers global fairness for the whole network with a CG (Centralized Grant) signal and, at the same time, offers local fairness between nodes with DG (Distributed Grant) signals. The DG signal is only meaningful to the next neighboring node. The local fairness is kept between two nodes in distributed way, but this distributed local fairness helps to keep the global fairness. Because the DG signal is related to the passed DG signal from the neighbor node. This protocol is rather simple but shows high performance than the already announced protocols.

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.
