Abstract

A technique is described whereby a data path controller is used in buffer insertion ring networks to eliminate delays associated with address recognition. In typical buffer insertion rings, each address station on the communications network has the ability to receive messages, pass over messages and originate messages of its own. The insertion buffer 10, as shown in the block diagram (Fig. 1), functions as a flexible buffering device and adds a delay in the pass-through data path. In addition, the insertion buffer 10 controls the difference between transmission and receiving speeds at a network station through the decision logic 11. It also has the ability to buffer pass-through data once the network station has initiated a local transmission.
