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. This memo provides
information for the Internet community.
This document is a product of the IP Performance Metrics Working Group of the IETF.
