RFC 5560: A One-Way Packet Duplication Metric, H. Uijterwaal2009-05-01T23:00:00-00:00In earlier work, a metric for packet loss was defined. This metric quantifies the case where a packet that is sent does not arrive at its destination within a reasonable time. In this memo, a metric for another case is defined: a packet is sent, but multiple copies arrive. The document also discusses streams and methods to summarize the results of streams. [STANDARDS-TRACK]
