Computer network with non-deterministic acces, but with deterministic access time

摘要

The system has a number of stations (S1..S5) communicating to a common medium (M) using non-deterministic protocol. Each station has a detector (CC) to detect whether there is a risk of detection with other stations. When a risk of collision is detected, the access time is limited to a maximum predetermined value. The value is chosen such that the sum of the maximum values chosen for all stations is lower than the mean rate that can be supported on the common medium.
