The draft briefs how TWAMP&OWAMP work and assigned a fixed UDP ports for TWAMP & OWAMP Test messages
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.
“ 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)."
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
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?
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?
