              OWAMP and TWAMP Well-Known Port Assignments
                   draft-ietf-ippm-port-twamp-test-03

Abstract

   This memo explains the motivation and describes the re-assignment of
   well-known ports for the OWAMP and TWAMP protocols for control and
   measurement, and clarifies the meaning and composition of these
   standards track protocol names for the industry.

   The memo updates RFC 4656 and RFC 5357, in terms of the UDP well-
   known port assignments, and clarifies the complete OWAMP and TWAMP
   protocol composition for the industry.

1.  Introduction

   The IETF IP Performance Metrics (IPPM) working group first developed
   the One-Way Active Measurement Protocol, OWAMP, specified in
   [RFC4656].  Further protocol development to support testing resulted
   in the Two-Way Active Measurement Protocol, TWAMP, specified in
   [RFC5357].

   Both OWAMP and TWAMP require the implementation of a control and mode
   negotiation protocol (OWAMP-Control and TWAMP-Control) which employs
   the reliable transport services of TCP (including security
   configuration and key derivation).  The control protocols arrange for
   the configuration and management of test sessions using the
   associated test protocol (OWAMP-Test or TWAMP-Test) on UDP transport.

   This memo recognizes the value of assigning a well-known UDP port to
   the *-Test protocols, and that this goal can easily be arranged
   through port re-assignments.
