CBWFQ--
Class-based weighted fair queueing. A queueing mechanism that extends the standard WFQ functionality to provide support for user-defined traffic classes.

DiffServ
--An architecture based on a simple model where traffic entering a network is classified and possibly conditioned at the boundaries of the network. The class of traffic is then identified with a DS codepoint or bit marking in the IP header. Within the core of the network, packets are forwarded according to the per-hop behavior associated with the DS code point.
DSCP
--Differentiated services code point. The six most significant bits of the 1-byte IP type of service (ToS) field. The per-hop behavior represented by a particular DSCP value is configurable. DSCP values range between 0 and 63.
IP
precedence
--The three most significant bits of the 1-byte type of service (ToS) field. IP precedence values range between zero for low priority and seven for high priority.
latency
--The delay between the time a device receives a packet and the time that packet is forwarded out the destination port.
marking
--The process of setting a Layer 3 DSCP value in a packet.
QoS
--Quality of service. A measure of performance for a transmission system that reflects its transmission quality and service availability.

RSVP
--Resource Reservation Protocol. A protocol for reserving network resources to provide quality of service guarantees to application flows.

WFQ
--Weighted fair queueing. A queue management algorithm that provides a certain fraction of link bandwidth to each of several queues, based on relative bandwidth applied to each of the queues.
WRED
--Weighted random early detection. A congestion avoidance mechanism that slows traffic by randomly dropping packets when there is congestion.
