This paper evaluates the performance of the switching arbiter based on priority polling concept, which is the core part of the internal high-speed switching fabric of open-architecture AICPS(Advanced Information Communication Processing System). The priority polling scheme enables versatile switching capabilities for the multimedia applications and flexibility for the characteristics of the network interface. In evaluating the performance, we used the method of analysis and simulation. We assumed the input traffic as either Poisson or MMPP, and the service discipline as polling frequency in accordance with each node's traffic load condition. When the 50:50 total traffic load ratio of the high-load ATM interface nodes to the relatively low-load line-interface ones is assumed, three times high ATM interface node polling frequency produces the optimal overall system performance while reducing the needed buffer size to 50% of the other general circular polling systems.
