Performance of Piggyback Ethernet

The performance of a new CSMA/CD protocol for a bus-type network is discussed. This protocol, called Piggy back Ethernet, can be viewed as a very simple and natural extension of commercial Ethernet. The performance of Piggyback Ethernet is compared with the performance of several other CSMA/CD protocols. In terms of global average measures, Piggyback Ethernet outperforms commercial Ethernet and all other bus protocols known to the authors. Although it appears to become unfair under heavy traffic conditions, it delivers better performance for all stations, when compared with other protocols.<>
