A device for switching data packets providing for local packet switching and non-local ATM switching. The device provides a packet switch coupled with LAN ports and provides for local switching between the LAN ports over the packet switch. Packets not known to be destined for data terminal equipment coupled with one of the ports are segmented and switched over an ATM backplane, switch or network.

LAN/ATM switch having local packet switching and an ATM core fabric

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.
