Abstract

A token ring network having virtual token rings comprised of one or more physical token rings. A media access control (MAC) layer device such as a bridge or switching hub has at least two ports assigned the same ring number such that token ring segments connected to the ports operate as though on the same physical token ring segment even though they are electrically isolated. All physical rings in the same virtual ring are considered to be in the same broadcast domain.
