Summary :

This paper proposes a new acknowledgement (ACK) delivery scheme performed in layer two, which gives the highest transmission priority to ACK delivery so as to enable higher ACK transmission speeds in networks using the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access procedure. This scheme is based on the principle of confirming ACK delivery through intentional collision. That is, an ACK is determined to have been received at the source adapter when a packet collision is observed after the end frame delimiter (EFD) of the return-packet. The throughput of a non-persistent CSMA/CD using the new scheme is then analyzed. This throughput is compared to the previously-proposed Acknowledge Ethernet type scheme. The analysis indicates that the new scheme yields a throughput several percent higher than the previous one. Application of the scheme to a 32 Mbit/s fiber-optic passive star network, or SOLARnet, is outlined. The experimental results obtained in a SOLARnet field trial are also reported and discussed.
