Performance of several buffering schemes using RCP

We use rotation counter protocol (RCP) for integrated services on a backbone network. The RCP is a token ring protocol that has in its token a special field for counting down of the number of packets transmitted in one cycle. By correlating the queuing performance of each station through the counter, the delay of the high-priority data can be made almost independent and the delay jitter made small. Thus the RCP can be utilized in a real-time control environment or an integrated services environment. We study and compare the effect of several buffering schemes for use in a backbone network
