Buffer Performance Analysis of Communication Processors During Slowdown at Network Control

by W.-M. Chow, L. Woo
An approximate model based on renewal theory has been developed for the performance analysis of communication processors during Network Control Program (NCP) slowdown. Performance values, which include cycle length, buffer utilization, and message loss, were computed as functions of traffic loads and user-assigned threshold values of free buffers were used for slowdown control. Comparison of results obtained by the approximate method with simulated results shows a high degree of accuracy for the approximation.
