EIA (Electronic Industries Association)
Organization that sets standards for electrical interfaces (connectors).
encapsulation
A method for moving messages across networks that use different types
of protocols. The message is encapsulated (rather than translated), so it
can move across a network that otherwise could not understand its
protocol. Encapsulating bridges and switches generally use proprietary
encapsulation schemes.
encode
To translate data into a series of electrical or optical pulses that can travel
efficiently over a cable or other medium.
entity
An active element within an Open Systems Interconnection (OSI)
network layer or sublayer.
extended LAN
A collection of LANs interconnected by protocol-independent bridges or
switches.
filter
An instruction to the FN10 to discard certain types of data packets.
filtering rate
A measure (in packets per second) of the FN10’s efficiency in examining
each frame, comparing it with an address table, and then deciding
whether to discard the frame or forward it.
forwarding rate
The rate (in packets per second) at which the FN10 can receive a stream
of packets from one network segment, complete all processing, and
transmit the packets to another network segment.
frame
A data message that includes a source address, destination address, data,
frame check sequence (FCS), and control information.
