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