RE: Protocol version re-negotiation
by Michael Brown 01 Mar '01

01 Mar '01

Hi Nancy, In 7.2.8, the reference to the value of the ServiceChange address says: "...(e.g., IP port number for IP networks)..." so that it is an example of what the value could be. Following is the ABNF for what the value could be which I don't believe precludes any type of addressing naming schema. serviceChangeAddress = ServiceChangeAddressToken EQUAL VALUE VALUE = quotedString / 1*(SafeChar) SafeChar = DIGIT / ALPHA / "+" / "-" / "&" / "!" / "_" / "/" / "'" / "?" / "@" / "^" / "`" / "~" / "*" / "$" / "\" / "(" / ")" / "%" / "|" / "." Admittedly, the specific "appropriate" usage is not definitively specified. I think it would be up to the MGC to evaluate the nature of the address. Michael -----Original Message----- From: Nancy Devin [mailto:nancy.devin@alcatel.com] Sent: Thursday, March 01, 2001 7:18 AM To: Brown, Michael [NC1:GW10:EXCH] Cc: ITU-SG16 Mail List; megaco(a)fore.com Subject: Re: Protocol version re-negotiation Good morning Michael, In RFC3015, section 7.2.8, it is mentionned that the serviceChangeAddress parameter specifies the address (IP port number) to be used. Can this also contain an IP address? In which cases is it using an IP address and in which cases is it using an IP port?

RE: Protocol version re-negotiation

AFAIK, that's the only way today. > > Can the MG Failover to itself? Will this cause any problems > in the MGC?

I think that's a scope add, which I for one am reluctant to do. If there was a real problem with something we already had, that's one thing, but a real feature add, I'm less thrilled about. I'll admit some of the things we have talked about stray at least close, if not over such a line. Here, I think an MG that can do a non-service affecting upgrade which is not redundant is pretty unusual these days - I don't mean to discourage folks from doing that, but I also don't feel we need changes in semantics (and some additional syntax, albeit some IANA registrations) to make it happen, it can wait for V2. > > Cheers, > Paul > > "Rosen, Brian" wrote: > > > > It's unlikely that we will do anything that adds > > new features by edits to the implementor's guide. > > It's reasonable to have explanatory text in such a > > document that is not normative. > > > > I think you failover, upgrade, and failover back > > with this version of the protocol. > > > > Brian > > > > > -----Original Message----- > > > From: Paul Rheaume [mailto:paul.rheaume@alcatel.com] > > > Sent: Thursday, February 22, 2001 1:00 PM > > > To: ITU-SG16 Mail List > > > Cc: megaco(a)fore.com > > > Subject: Re: Protocol version re-negotiation > > > > > > > > > Folks, > > > > > > Where is the appropriate list to discuss this issue? > > > > > > We feel that version negotiation and the version upgrade > > > process is not > > > well specified and needs to be discussed and properly > defined at the > > > latest in version 2 of the specification.

Re: H.248 Syntax im H.323 Annex L
by Paul, Manoj 26 Feb '01

26 Feb '01

Hi John, Is it not that we are just emulating MGCP model in the Stimuls COntrol Protocol provided by H.323 Annex L? I mean, the way a MGC controls an MG using H.248, an Annex L Feature Server controls an H.323 endpoint. According to my understanding it is just that H.248 is used "as is" for the later. Why do we need to tunnel H.248 and between what entities in the network? I shall appreciate your comments in this. thanks Manoj. -----Original Message----- From: Li, John [mailto:John.Li@Dialogic.com] Sent: Monday, February 26, 2001 12:15 PM To: 'Paul, Manoj' Subject: RE: H.248 Syntax im H.323 Annex L I think, By doing that, H.248 information can be tunneled within h.245 messages, so the H.248 section can be processed by a MEGACO entity directly for interoperability. Although BER was not a optimal solution (nor was SDP) for encoding in MEGACO, SIG 16 allows it to be used. John -----Original Message----- From: Paul, Manoj [mailto:mpaul@TRILLIUM.COM] Sent: Monday, February 26, 2001 2:13 PM To: ITU-SG16(a)mailbag.cps.INTEL.COM Subject: H.248 Syntax im H.323 Annex L Hi All, Could someone point out the reason for keeping h248Message codepoint as OCTET STRING in stimulusControl IE in H.323 Version 4 for Annex L support. H.323 Annex L specifies h248Message as OCTET STRING in stimulusControl code point. This surely saves importing H.248 ASN.1 syntax in H.323, but it does require the user to encode/decode H.248 PDUs as text/BER. And then re-encode the H248 message as an OCTET STRING using PER in H.323 UUPDU. Was there any reason why the specific H.248 codepoints were not imported in H.323 so that the user may have to use only PER encode scheme to encode simulusControl IE. Does not the earlier approach necessiates the user to have H.248 implementation with H.323 to support Annex L? Thanks for your time, Manoj Paul.

Re: Quick question on a Request for package registration
by Tom-PT Taylor 26 Feb '01

26 Feb '01

3GPP is a public forum, and I believe their packages would be viewed as public. I'll note that it is desirable that the packages be considered technically stable (though perhaps subject to some editing and minor adjustment) before they are registered. I've copied various parties for coordination purposes. > -----Original Message----- > From: IANA [mailto:iana@iana.org] > Sent: Friday, February 23, 2001 5:28 PM > To: Taylor, Tom-PT [NORSE:B881:EXCH] > Subject: FW: Quick question on a Request for package registration > > > Tom, > > Quick question.

Re: Protocol version re-negotiation
by Rosen, Brian 23 Feb '01

23 Feb '01

It's unlikely that we will do anything that adds new features by edits to the implementor's guide. It's reasonable to have explanatory text in such a document that is not normative. I think you failover, upgrade, and failover back with this version of the protocol.
