Switch User's Manual

74 S
SSL Acceleration Module (SAM)
Intelligently accelerates secure business
transactions and confidential data by off-loading
SSL processing from local servers without
imposing delays on other traffic in the same data
path.
sustainable cell rate (SCR)
The expected rate of cell transmission on a
nonconstant bit rate (CBR) transmission.
Switch Fabric (SF)
In signal computing system architecture
(SCSA), the facility that connects two (or more)
transmitting or receiving service providers.
Network interfaces reside on line cards that
provide connection between a switch fabric and
external networks.
Switch Fabric/Central Processor Unit (SF/CPU)
The board that resides in slot 5 or 6 of the Nortel
Ethernet Routing Switch 8600 system chassis.
switched multimegabit data service (SMDS)
A connectionless, broadband, packet-switched
data service that provides LAN-like performance
and features in metropolitan or wide areas.
synchronous digital hierarchy (SDH)
A European digital transmission hierarchy based
on time division multiplexing.
Synchronous Dynamic Random Access Memory
(SDRAM)
A form of dynamic random access memory
(DRAM) that can run at higher clock speeds than
conventional DRAM. SDRAM employs a bursting
technique in which the DRAM predicts the
address of the next memory location to access.
synchronous optical network (SONET)
A family of fiber optic transmission rates that
provides the flexibility to transport many digital
signals with different capacities. This American
