This memo defines a metric to quantify an IP network's ability to transfer packets in both directions from one host to another host. Two-way communication is almost always needed; thus, failure to transfer a packet in either direction constitutes a round-trip packet loss.

Internet Engineering Task Force (IETF)                         A. Morton Request for Comments: 6673                                     AT&T Labs Category: Standards Track                                    August 2012 ISSN: 2070-1721

                      Round-Trip Packet Loss Metrics


   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).
