DMZ Demilitarized Zone
In computer security, DMZ is a physical or logical
sub-

DSCP Differentiated Service or
DiffServ
DSCP
is a computer networking architecture that
specifies a simple, scalable and coarse-grained
mechanism for classifying, managing network traffic
and providing Quality of Service (QoS) guarantees on
modern IP networks. DiffServ can, for example, be
used to provide low-latency, guaranteed service (GS) to
critical network traffic such as voice or video while
providing simple best-
effort traffic guarantees to
non-critical services such as web traffic or file transfers.
DiffServ uses the 6-bit Differentiated Services Code
Point (DSCP) field in the header of IP packets for
packet classificatio
n purposes. DSCP replaces the
outdated IP precedence, a 3-bit field in the Type of
Service byte of the IP header originally used to classify
and prioritize types of traffic.
