Paper Abstract

In creating a higher level ethernet model the important effects of the ethernet bus on a PACS system must be taken into consideration. These effects include the delay in time between the submission of an image for transmission and the time the last packet arrives at the receiving node, and the retransmission of packets due to collisions. A good image-level model should approximate the statistical characteristics of the image delay over a range of network loading. It should also predict the number of packets which will require retransmission and the statistical characteristics of this effect over a range of loading. This paper describes the approach used to create such a model and compares the results obtained when using the BONeS model at the packet and image levels. It is shown that the approximate image-level ethernet model is much faster than the packet-level simulation while also providing accurate results. The impact of packet loading time on ethernet fairness is also discussed.
