Terminology
Bridged Traffic: See “Switched Traffic”, below.
DA: The acronym for Destination Address. In an IP packet, this is the
destination IP address carried in the header, and identifies the destination
intended by the packet’s originator. See also “SA”.
Routed Traffic: Traffic moving from an SA in one VLAN to a DA in a different
VLAN.
SA: The acronym for Source Address. In an IP packet, this is the source IP
address carried in the header, and identifies the packet’s originator. See also
“DA”.
Switched Traffic: Traffic moving from an SA in a given VLAN to a DA in the
same VLAN. (Sometimes termed “bridged traffic”.)
Throttle: For connection-rate filtering applications, this means to tempo-
rarily block traffic from a host exhibiting a relatively high incidence of
attempts to connect with other devices. Traffic is blocked from the host for
a calculated period of time, and then allowed to resume. If the undesired
behavior persists, the cycle is repeated.
