Abstract

The contention-based lookahead reservation (CLAR) protocol can provide fast circuit-switching services that are particularly advantageous for networks supporting integrated services. The delay and throughput performance for message transmission are obtained, and they agree closely with that obtained by simulation. The delay performance of CLAR is similar to that of the M-CSMA protocol for an M-channel network, but only CLAR can give a stable maximum throughput of (M-1)/M independent of the cable length. Moreover, CLAR requires only two sets of transceivers, while M-CSMA requires M. The lookahead reservation technique can provide 9% throughput increase for fixed-size messages and 19% for geometrically distributed messages
