1000BASE-T
A designation for the type of wiring used by Ethernet networks
with a data rate of 1000 Mbps.
binary
The "base two" system of numbers, that uses only two digits, 0
and 1, to represent all numbers. In binary, the number 1 is written
as 1, 2 as 10, 3 as 11, 4 as 100, etc. Although expressed as
decimal numbers for convenience, IP addresses in actual use
are binary numbers; e.g., the IP address 209.191.4.240 is
11010001.10111111.00000100.11110000 in binary. See also bit,
IP address, network mask.
bit
Short for "binary digit," a bit is a number that can have two values,
0 or 1. See also binary.
bps
bits per second
CoS
Class of Service. Defined in 802.1Q, the value range is from 0 to
7. Due to 4 internal traffic class mapping to 8 priority, Only Cos
value 0,2,5,7 are valid according to Cos Queue Mapping.
broadcast
To send data to all computers on a network.
Ethernet
The most commonly installed computer network technology,
usually using twisted pair wiring. Ethernet data rates are 10 Mbps
and 100 Mbps. See also 10BASE-T, 100BASE-T, twisted pair.
filtering
To screen out selected types of data, based on filtering rules.
Filtering can be applied in one direction (ingress or egress), or in
both directions.
