Glossary
congestion control preventing a sender from overwhelming the network, wherein the network is prevented from becoming congested. flow control preventing a sender from overwhelming a receiver wherein traffic is controlled between a sender and receiver such that only the receiver controls the transmission rate. policing performing an action (typically transmit/pass) to packets that conform to a specified rate and performing another action (typically drop) to packets that violate that rate. Quality of Service, QoS description or measurement of the overall performance of a service, typically represented by packet loss, bit errors, bit rate, throughput, goodput, delay, availability or jitter. queuing and scheduling splitting traffic into a plurality of queues or buffers based on various criteria ( such as type of packet, QoS requirements or user) so that a scheduler can decide which packet to service next based on a service discipline e.g. longest queue first, round robin. traffic shaping a bandwidth management technique to make traffic conform to a certain rate by delaying the transmission of packets in a buffer. Delayed packets may be subsequently transmitted/released as bandwidth becomes available.
