Improvement of traffic bias characteristics and acknowledgement method for MULTISTAR LAN
Abstract
MULTISTAR was proposed as a system to improve header-driven storageless (HDSL) local area network (LAN) to transmit simultaneously more than one frame, but it has a problem in that the throughput is deteriorated for the high or biased load.
This paper presents two improvements for MULTISTAR LAN: One is that the tournament switch is devised as a means to realize the multiinput arbiter and is used instead of the input arbiter; and the other is that a system is devised where the central node can notify the passage of a packet to the originating side. The performances of those two new MULTISTAR configurations are evaluated by simulation. It is then demonstrated that the system implementing those new ideas exhibits a drastic improvement in the efficiency, compared to the original MULTISTAR LAN.
