Dear Tao, What you say is correct: considering real-time communications, ALTO can not only be beneficial for peers behind middleboxes, but also in other cases.

Can the broader relay application(not > only > for NAT traversal) be integrated into ALTO? The problem statement draft gives examples for use cases to motivate the need for ALTO. I think for that purpose the example of NAT traversal for real-time communications is sufficient. If you think your additional use case affects ALTO requirements (i.e., it motivates additional requirements not yet included in the requirements draft [draft-kiesel-alto-reqs]), this needs to be discussed, of course. Currently, I do not see how the example you give below asks for additional requirements for an ALTO client-server protocol which are not already included in [draft-kiesel-alto-reqs]. But please elaborate on this list if you think so and specifically what those requirements are. - Jan > -----Original Message----- > From: Tao Ma [mailto:[email protected]] > Sent: Donnerstag, 2.
