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.
