TWAMP

two-way active measurement protocol

Two-way Active Measurement Protocol (TWAMP), based on the One-way Active Measurement Protocol (OWAMP), adds two-way or round-trip measurement capabilities. The TWAMP measurement architecture is usually comprised of two hosts with specific roles. Devices that implement TWAMP provide the capability to identify performance issues on all IP network segments. TWAMP initiates a control session between any two points in the network using TCP and then sends a test session using UDP packets. The UDP test packets are sent from the client and are reflected by the server, providing a round-trip measurement.
