Abstract
A method is disclosed for implementing a token ring network on a token bus network. In accordance with the invention a token ring node is connected to each one of a plurality of token bus nodes such that the token ring node appears to the token bus node to which it is connected as station equipment and the token bus node appears to the token ring node as both the next token ring node and the preceeding token ring node in a ring network. A message is transmitted from a token ring node by forming a token ring frame and transmitting the token ring frame to the next token ring node which is the token bus node to which the token ring node is connected. The token bus node encapsulates the token ring frame that it receives in a token bus frame and transmits the resulting token bus frame to a destination bus node. The destination bus node receives the token bus frame, removes the token ring frame that is encapsulated therein and forwards the token ring frame to the token ring node connected to the destination bus node.
