TWAMP (Two-Way Active Measurement Protocol)
TWAMP (Two-Way Active Measurement Protocol) is an open protocol for measuring network performance between any two devices supporting the TWAMP protocol. The TWAMP protocol is used to set up performance measurement sessions. Based on the OWAMP, it adds two-way or round-trip measurement capabilities. The TWAMP measurement architecture is usually comprised of two hosts with specific roles, and this allows for some protocol simplifications.
