Analysis of a link layer protocol for high speed data bus

A parallel data bus based on the slotted ring idea with destination release policy is proposed and analyzed. Analytical results are compared to simulations and actual measurements carried out in a test network with a 200-Mb/s data rate. Transfer delays are calculated by mathematical analysis and computer simulation for networks with five and eight nodes with Poisson distributed load. Two different destination address distributions are used, i.e., uniform and geometric. The results indicate good performance for a large range of load. Potential applications include a back-plane bus for multiprocessor systems, and a local fiber optic network for real-time traffic, e.g., multimedia applications
