LAN ノ タジュウカ トクセイ ニツイテ

The spread of computer network that have intelligent terminals, for example, mini computer, personal computer, etc, enhances the value of LAN network more and more in accordance with the effective utilization of computer resource and the practical use of distributed process form. Especially, LAN network is expected that the network is applicable to the use\u27s intimate needs within a limited geographycal area as a office building, a factory, and a university area with a cheap costs. In order to operate a LAN as a communication network, we must provide a communication rules which is called as protocol. Many protocol for LAN have been proposed in these days. CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol is the representative among them. In this paper, on the basis of the traffic performance valuation of 1-prsisthent CSMA/CD protocol, we considered the relation between bit rate (bit per second) and packet legth and packet multiplexing, the relation between packet multiplexing, and the feasibility of multiplexing. As a result, it made clear that if high-rate was got and packet length was created the suitable one, many information could be transported. And even if high bit rate is not got, many information can be transported by realizing the channel multiplexing
