About the SuperStack II Switch 2000 TR 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.
