Abstract Abstract
Many user applications (and the transport protocols that make them Many user applications (and the transport protocols that make them
possible) require two-way communications. To assess this capability, possible) require two-way communications. To assess this capability,
and to achieve test system simplicity, round-trip loss measurements and to achieve test system simplicity, round-trip loss measurements
are frequently conducted in practice. The Two-Way Active Measurement are frequently conducted in practice. The Two-Way Active Measurement
Protocol specified in RFC 5357 establishes a round-trip loss Protocol specified in RFC 5357 establishes a round-trip loss
measurement capability for the Internet. However, there is currently measurement capability for the Internet. However, there is currently
no metric specified according to the RFC 2330 framework. no metric specified according to the RFC 2330 framework.
