A simulation model of an Ethernet local area network is described. The model is used to examine the performance of the truncated exponential backoff algorithm under conditions of heavy loading. At high loading levels the current backoff algorithm tends to generate a large queue of deferring nodes and thus perpetuates the collision interval. A new backoff algorithm is proposed which reduces the number of collisions on the network, resulting in shorter delay times. Comparitive results are presented for the current and proposed algorithms. At offered loads greater than 100%, a reduction in delay times of 10% and 25% is obtained for 512 and 64 byte packet lengths, respectively.
