Abstract :
The author presents a new logical link control (LLC) protocol for carrier sense multiple access with collision detection (CSMA/CD) networks called fast select connection-oriented (FS-CO) and evaluates the performance. He develops an approximate analytical model of a network under the slotted nonpersistent CSMA/CD protocol with a priority acknowledgment scheme and the FS-CO-LLC protocol. He also makes a performance comparison of the FS-CO-LLC, a CO LLC, and a connectionless (CL) LLC protocol. The comparison reveals that the FS-CO-LLC always outperforms the CL-LLC and that it performs better than the CO-LLC if the average message length h is not so large compared to the receive-buffer size. It is also found that even with large values of h the performance of the FS-CO-LLC does not degrade much in comparison with the CO-LLC
