In basic terms, a packet-switching device provides forwarding logic for packets
incoming or outgoing on two or more network interfaces on the device. The
forwarding logic on Cabletron’s MMAC-Plus architecture devices is based on
three separate modes:
incoming or outgoing on two or more network interfaces on the device. The
forwarding logic on Cabletron’s MMAC-Plus architecture devices is based on
three separate modes:
•
Traditional 802.1d bridging based on physical layer address information.
•
Traditional IP Routing based on logical layer address information.
•
SecureFast™ Switching, which is high-performance switching based on source
and destination MAC (physical) layer addresses. Packets received from a
source address on a module’s protocol-dependent front panel network are
converted into fixed-length, protocol-independent packets for transmission
across a backplane, and then are re-converted at the destination device into the
appropriate physical frame format for reception by the destination address.
Future firmware and management software enhancements will allow an
administratively defined connection-policy between end stations connected to
SecureFast Switching devices.

The INB is the Cabletron-proprietary network bus for protocol-independent,
high-speed packet or cell switching between connectivity modules that support
front-panel Ethernet, FDDI, Token Ring, or ATM networks. The connectivity
modules incorporate Cabletron’s SecureFast Switch (SFS) technology to provide
high-performance packet switching based on source and destination MAC
addresses, rather than on internet protocol (IP) addresses. By basing packet
