708 Glossary
SR/TLB source-route translational bridging: A bridging method that
allows source-route stations to communicate with transparent bridge stations
aided by an intermediate bridge that translates between the two bridge
protocols. Used for bridging between Token Ring and Ethernet. Compare
with: SRT.
SSAP Source Service Access Point: The SAP of the network node identified
in the Source field of the packet. See also: DSAP and SAP.
SSE Silicon Switching Engine: The software component of Cisco’s silicon
switching technology, hard-coded into the Silicon Switch Processor (SSP). Silicon
switching is available only on the Cisco 7000 with an SSP. Silicon-switched
packets are compared to the silicon-switching cache on the SSE. The SSP is a
dedicated switch processor that offloads the switching process from the route
processor, providing a fast-switching solution, but packets must still traverse the
backplane of the router to get to the SSP and then back to the exit interface.
standard IP access list IP access list that uses only the source IP addresses
to filter a network.
standard IPX access list IPX access list that uses only the source and destination
IPX address to filter a network.
star topology A LAN physical topology with endpoints on the network
converging at a common central switch (known as a hub) using point-topoint
links. A logical ring topology can be configured as a physical star
topology using a unidirectional closed-loop star rather than point-to-point
links. That is, connections within the hub are arranged in an internal ring.
See also: bus topology and ring topology.
startup range If an AppleTalk node does not have a number saved from
the last time it was booted, then the node selects from the range of values
from 65280 to 65534.
state transitions Digital signaling scheme that reads the “state” of the
digital signal in the middle of the bit cell. If it is five volts, the cell is read as
a one. If the state of the digital signal is zero volts, the bit cell is read as a zero.
static route A route whose information is purposefully entered into
the routing table and takes priority over those chosen by dynamic routing
protocols.
