Register insertion/self-token protocol for ring LANs

A new multiple-token ring access control scheme, referred to as the register insertion with self-token protocol, is described. In the protocol, each node distributed on a ring has a private token, called a self-token, and a fixed-length register to carry out register insertion control. The protocol, then, is expected to have good properties, inherited from both register insertion control and token access control schemes. A comparison between the register insertion/self-token protocol and the IEEE 802.5 is carried out
