 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 previously requested and accepted to start
    and stop at the same time.

    test sessions which the Individual Session Control feature can then
    manage (start/stop).
 
    This memo is an update to the TWAMP core protocol specified in
    [RFC5357].  Measurement systems are not required to implement the
    feature described in this memo to claim compliance with [RFC5357].
 
    Throughout this memo, the bits marked MBZ (Must Be Zero) MUST be set
    to zero by senders and MUST be ignored by receivers.  Also, the HMAC
