ResumoThe overhead introduced by communications software significantly impacts the performance of most distributed applications. To derive the optimum performance from a distributed application and to determine areas for improvement in new communication protocols, it is essential to identify the factors that affect communication delay. This paper examines two factors that affect the performance of communication protocols: the granularity of communication and traffic at a host's network interface. Three transport mechanisms, the Transmission Control Protocol, the User Data Protocol, and DECnet, utilizing an Ethernet local area network are considered. Results are reported for an experimental study using a dedicated network monitor. The results demonstrate the influence of these two factors on communication protocols. Based on results for UDP and DECnet, models for estimating delay are presented. Suggestions are also made for the improvement of future transport protocols and for methods to reduce communication delay in distributed applications.
