Imminent access recognition: A protocol for integrated traffic on a CSMA/CD local area network
D. Girma, John A. Dunlop · Journal of the Institution of Electronic and Radio Engineers · 1988
A technique is described for reducing the delay of speech packets caused by collisions with other packets on Ethernet. This improvement is achieved by incorporating a contentionfree mechanism during periodic packet transmission. The technique, ‘Imminent Access Recognition’, is easily implemented in hardware as an enhancement to an Ethernet node controller. Simulation models are used to estimate performance and suggest that the lmminent Access Recognition protocol has a significant advantage over CSMA/CD.
