Reviewer: Linda Dunbar Review result: Ready with Issues I am the assigned Gen-ART reviewer for this draft. The General Area Review Team (Gen-ART) reviews all IETF documents being processed by the IESG for the IETF Chair. Please treat these comments just like any other last call comments. For more information, please see the FAQ at <https://trac.ietf.org/trac/gen/wiki/GenArtfaq>. Document: draft-ietf-ippm-port-twamp-test-?? Reviewer: Linda Dunbar Review Date: 2018-11-26 IETF LC End Date: 2018-11-26 IESG Telechat date: 2018-12-06 Summary: The draft briefs how TWAMP&OWAMP work and assigned a fixed UDP ports for TWAMP & OWAMP Test messages Major issues: Section 5.1 states that the UDP port used for TEST are negotiated, whereas the IANA section of this document states the explicit fixed UDP port . Does it mean the negotiation is no longer needed? Than all TEST messages are on the same UDP ports? Makings it not effective in making test messages traversing different ECMP paths. Why? “ Section 3.5 [RFC5357] describes the detailed process of negotiating the Receiver Port number, on which the TWAMP Session-Reflector will send and receive TWAMP-Test packets. The Control-Client, acting on behalf of the Session-Sender, proposes the Receiver port number from the Dynamic Port range [RFC6335]: "The Receiver Port is the desired UDP port to which TWAMP-Test packets will be sent by the Session-Sender (the port where the Session-Reflector is asked to receive test packets). The Receiver Port is also the UDP port from which TWAMP-Test packets will be sent by the Session-Reflector (the Session-Reflector will use the same UDP port to send and receive packets)." Minor issues: Does the following sentence mean the UDP port was already assigned to to OWAMP & TWAMP control? “ Since OWAMP-Control and TWAMP-Control require TCP transport, they cannot make use of the UDP ports which were originally assigned. However, test sessions using OWAMP-Test or TWAMP-Test operate on UDP transport.” The text then states that “Use of this UDP port is OPTIONAL in standards-track OWAMP and TWAMP. “ If not using UDP ports, does it mean that the TCP ports are uses for OWAMP-TEST & TWAMP-TEST? Nits/editorial comments: the head note has “WAMP W-K UDP Ports” as the title which is different from the draft title. P.s. what does W-K mean?
