Abstract The CSMA/CD method, one of the communication schemes for bus‐type LANs, has problems with respect to transmission capability and its function. This paper presents an access control method named multichannel CSMA/CD for local area networks. In this method, CSMA/CD combined with a new load distribution mechanism and channel selection function is extended to multichannel organization. This method aims at LANs having high performance and multiple functions. As a result of performance evaluation, multichannel CSMA/CD is shown to be superior to the original CSMA/CD with respect to (1) total transmission capacity, (2) throughput‐delay characteristic performance, (3) channel stability and (4) adaptability to various kinds of user demands in networks.
