Technical Summary Packet delay variation metrics appear in many different standards documents. The metric definition in RFC 3393 has considerable flexibility, and it allows multiple formulations of delay variation through the specification of different packet selection functions. Although flexibility provides wide coverage and room for new ideas, it can make comparisons of independent implementations more difficult. Two different formulations of delay variation have come into wide use in the context of active measurements. This memo examines a range of circumstances for active measurements of delay variation and their uses, and recommends which of the two forms is best matched to particular conditions and tasks. Working Group Summary This document was suggested after a talk on this topic at IETF-65. There was no controversy in the WG process. Consensus was smooth. Personnel The document shepherd is Henk Uijterwaal (email@example.com). Lars Eggert (firstname.lastname@example.org) has reviewed this document for the IESG.
