Filed: 1981-10-08
Abstract: PURPOSE:To simplify congestion processing software by monitoring the cyclic period of a GAF (go-ahead flag) at each node of a token-passing type decentralized loop network. CONSTITUTION:At each node, a go-ahead flag detecting circuit GAFDET which detects a go-ahead flag circulating in a loop network is provided.

When the cyclic period exceeds a specified reference value, the counter CNT informs a central controller CPU of the congestion state of the network. Then, the CPU inhibits new calling of its equipped terminal equipment.
