TWAMP
Two Wire Active Measurement Protocol
TWAMP is an open protocol defined in RFC 5357 which is used to measure the network performance between two devices that support the TWAMP protocol. It utilizes two protocols, TWAMP-Control and TWAMP-Test. In addition, there are two variants, TWAMP and TWAMP Light. The TWAMP control and reflector entities involved exchange packets as part of a session. Reflected packets are timestamped, enabling performance of the network to be measured.
