Performance evaluation of multipoint communication on HIPPI over ATM networks

High Performance Parallel Interface (HIPPI) is primarily for channel technique and provides a simplex point-to-point interface for transferring data at a peak rate of 800 or 1600 Mbps over distances of up to 25 meters. In order to extend the use of HIPPl from a channel solution to a networking solution, the physical limitation of HIPPI must be solved. The HIPPI-ATM mapping can be one of the possible solutions and allow communication over a relatively long distance by using HIPPI-ATM converters. In this paper, we first suggest that the multipoint-to-multipoint communication of HIPPI over ATM networks does not perform well although an unique flow control between source-site and destination-site HIPPI-ATM converters is applied on each connection. In order to effectively establish multipoint-to-multipoint communication, we thus propose additional flow control schemes on HIPPI over ATM networks, that is, Peak-rate control scheme and Connection control scheme. We further formulate both throughput and packet transmission delay performance under these schemes and compare the performance and the complexity of the implementation of both schemes.
