RFC 4656: A One-way Active Measurement Protocol (OWAMP), S. Shalunov, B. Teitelbaum, A. Karp, J. Boote, M. Zekauskas2006-09-01T23:00:00-00:00The One-Way Active Measurement Protocol (OWAMP) measures unidirectional characteristics such as one-way delay and one-way loss. High-precision measurement of these one-way IP performance metrics became possible with wider availability of good time sources (such as GPS and CDMA). OWAMP enables the interoperability of these measurements. [STANDARDS-TRACK]
