Individual Session Control Feature
for the Two-Way Active Measurement Protocol (TWAMP)
Abstract
The IETF has completed its work on the core specification of TWAMP --
the Two-Way Active Measurement Protocol. This memo describes an
OPTIONAL feature for TWAMP, that gives the controlling host the
ability to start and stop one or more individual test sessions using
Session Identifiers. The base capability of the TWAMP protocol
requires all test sessions that were previously requested and
accepted to start and stop at the same time.
