TR-in-FE Module

The SuperStack II Switch 2000 TR TR-in-FE module

combines Token Ring and Fast Ethernet (FE) for the

purpose of utilizing FE as a backbone and method of

high-speed server attachment for TR networks.

TR-in-FE complements ATM and FDDI methods of

high-speed integration by providing an option to help

TR users evolve their network's core infrastructure

while preserving their existing equipment and appli-

cations.

TR-in-FE uses Fast Ethernet to transport natively for-

matted Token Ring frames. Both source route and

transparent TR frame addressing information is main-

tained through the FE infrastructure. This allows stan-

dard TR workstations and servers to use the fast

transport without modiﬁcation, or special FE servers

to communicate to the native TR community.
