RE: Question on a NAT traversal requirement

Hi, If you read my response you will see that this requirements comes are there since the requirement when written took into account that one solution will be based on the H.323 extension mechanisms that require those H.323, H.225.0 and H.245 versions. So systems that are H.323 V2 will not be able to support H.460.18 and H.460.19. Possibly it is that to implement H.40.18 and H.460.19 you need those H.323 versions and above. Like I mentioned if you use SBC or ALGs then this is not required and the SBC and ALG will also support H.323 V2 and V1(if there are) product.

Mr. Okubo, This statement is there since the in order to allow solutions that will require the extensibility framework and generic parameters defined only from those versions. This means that any version from this version and above will work. It also means that NAT traversal may work with older systems using other NAT traversal mechanisms like Session Border Controllers or ALGs Roni Even > -----Original Message----- > From: OKUBO Sakae [mailto:okubo@MXZ.MESH.NE.JP] > Sent: Tuesday, August 22, 2006 11:10 AM > To: itu-sg16(a)external.cisco.com > Subject: Question on a NAT traversal requirement > > Dear NAT traversal experts, > > TTC (The Telecommunication Technology Committee) is now working on > Technical Paper "Requirements for Network Address Translator and > Firewall Traversal of H.323 Multimedia Systems" to convert it to a > Technical Report in Japanese language. > > I have a question on how to interpret the following part: > > ---------- > 9.3 Requirements on Signalling and Media Streams > b) NAT traversal mechanisms for H.323 multimedia systems shall > support no less than ITU-T H.323v3, H.245v7, H.225.0v4, and H.235v3. > All later versions of H.323, H.245, H.225.0 and H.235 may be > supported. > ---------- > > Take an example of H.323 that has now v6.

Question on a NAT traversal requirement
by OKUBO Sakae 22 Aug '06

22 Aug '06

Dear NAT traversal experts, TTC (The Telecommunication Technology Committee) is now working on Technical Paper "Requirements for Network Address Translator and Firewall Traversal of H.323 Multimedia Systems" to convert it to a Technical Report in Japanese language. I have a question on how to interpret the following part: ---------- 9.3 Requirements on Signalling and Media Streams b) NAT traversal mechanisms for H.323 multimedia systems shall support no less than ITU-T H.323v3, H.245v7, H.225.0v4, and H.235v3. All later versions of H.323, H.245, H.225.0 and H.235 may be supported. ---------- Take an example of H.323 that has now v6. Which of the following statements are true? NAT traversal 1/ shall not support v1 or v2. 2/ may support v1 or v2. 3/ shall support v3. 4/ shall support v3 and in addition may support any combinations of v4, v5 and v6. 5/ shall support v3 and may support v4, or (v4 and v5), or (v4, v5 and v6). In other words, NAT traversal with the following support conforms to this requirement: a/ v3 b/ v4 c/ v5 d/ v6 e/ v3, v4 f/ v3, v5 g/ v3, v6 h/ v3, v4, v5 i/ v3, v4, v5, v6 j/ v4, v5 k/ v4, v6 l/ v4, v5, v6 m/ v5, v6 -- Best regards, OKUBO Sakae e-mail: okubo(a)aoni.waseda.jp (<== sokubo(a)waseda.jp, valid until 31 March 2007) Visiting Professor Global Information and Telecommunication Institute (GITI) Waseda University ****************************************************************** Waseda University, YRP Ichibankan 312 Tel: +81 46 847 5406 3-4 Hikarinooka, Yokosuka-shi, Kanagawa-ken Fax: +81 46 847 5413 239-0847 Japan H.323 videoconferencing: arranged by advice ******************************************************************
