Simple to configure and administer
TR-in-FE allows both Token Ring and Ethernet to
share the same Fast Ethernet physical wiring infra-
structure and server base without impacting network
performance. TR-in-FE accomplishes this by introduc-
ing routing or traditional bridging via Source-Route to
Transparent translation.
Fast Ethernet is relatively well understood and easy to
configure. Additionally, many tools exist to manage
and administer Fast Ethernet due to its wide accep-
tance in the industry and its similarity to Ethernet.
TR-in-FE benefits MIS managers most interested in:
■
Preserving existing investments in TR infrastructure
■ Seeking low-cost, high-speed connectivity
■
Combining Ethernet and Token Ring for common
server access
Fast Ethernet is less expensive than other options,
such as FDDI and ATM. Using FE, the price per port
for server attachment is 20% that of ATM and FDDI.
Token Ring switching allows the install base of TR
equipment and its configuration to remain intact and
operational while allowing for an upgrade to higher
performance through microsegmentation and inter-
faces to higher speed technologies. TR-in-FE repre-
sents one option for integrating Fast Ethernet into the
TR switched environment.
