OWAMP

OWAMP stands for One-Way Average Measurement Protocol. It is a network measurement protocol designed to measure one-way IP performance metrics such as packet loss and delay variation, also known as jitter. OWAMP is an extension of the two-way active measurement protocol (TWAMP) and addresses some of its limitations by enabling one-way measurements. This is particularly useful in scenarios where synchronized clocks between the measurement endpoints are not feasible or when measuring across different administrative domains.

The protocol operates by having a control connection between two endpoints, a reflector and a client. The client requests specific measurement tests from the reflector. These tests involve sending timestamped data packets from the client to the reflector and potentially from the reflector back to the client. By analyzing the timestamps of these packets at both ends, one-way delay and loss can be calculated. OWAMP is defined in RFC 5938 and has found applications in network monitoring, performance troubleshooting, and capacity planning. It provides a standardized method for obtaining valuable performance data that complements other network measurement techniques.
