Abstract
Cabletron's SecureFast VLAN (SFVLAN) product implements a distributed
connection-oriented switching protocol that provides fast forwarding
of data packets at the MAC layer. The product uses the concept of
virtual LANs (VLANs) to determine the validity of call connection
requests and to scope the broadcast of certain flooded messages.
