Abstract
We have developed a novel analytical Ethernet performance model that contains a complete formulation of system response time from the initiation of user requests for service to the delivery of the service to the user. The estimated response time includes simultaneous input bus delay (requests for service from multiple users), simultaneous output delay (responses to requests from multiple servers), considering time lost to collisions and subsequent backoff time, time lost to deferring transmission due to a busy channel, and transmission time. In addition, we include server disk input and output queueing times and server and user disk access times. By modeling all epochs of collision, backoff, and transmission events, we have developed a way of providing a level of detail and accuracy that other analytic models of Ethernet performance do not provide. In addition to using the model for estimating response time as a function of number of users and servers, the model is used to determine the number of servers that would be appropriate for a given range of number of users.
