Re: [ANCP] Question about the Tech Type in draft-ietf-ancp-protocol-05

[Sanjay Wadhwa <[e-mail]>]

  Tech Type was originally specified in GSMPv3 drafts (post RFC). 0x01-0x04 was intended to be allocated for existing technologies that were trying to leverage GSMP at the time. Given "Tech type" is not part of base GSMP RFC, and is an ANCP specific extension, it makes sense to define ANCP specific "Tech type" registry where 0x01-0x04 should be available for allocation (we can update the ANCP protocol draft). We don't need to change what has been allocated for DSL (0x05) though. We will need to allocate a value for PON.

Hi all,

Given no further response on this thread, I assume almost none of the people in the ANCP mailing list knows what those technologies indicated by Tech Type values of 0x01~0x04 are.

If Sanjay was right that the Tech Type would a new IANA registry, then according to the charter of ANCP WG, only the DSL and PON (newly added) technologies should be defined and maybe we should withdraw the allocation of 0x01~0x04.

But since PON is now in the charter, we should anyway allocate a Tech Type value for PON.

Hi Sanjay,

Thank you very much for your answer.

But in the text in section 5.4.1.1 as follows, if the tech type is new registry, then what types of technologies are the 0x01 ~ 0x04 indicates respectively? I think they should be clearly specified, although I guess they might be 0x01 for 802.3, 0x02 for 802.11a/b/g, 0x03 for 802.163, 0x04 for 802.16m. Is it correct?

"Tech Type

         An 8-bit field indicating the applicable technology type value.
         The Message Type plus the Tech Value uniquely define a single
         Extension Type and can be treated as a single 16 bit extension
         type.  "Tech Type" value of 0x05 SHOULD be used by ANCP for DSL
         technology.

            0x00 Extension block not in use.

            0x01 - 0x04 Already in use by various technologies

            0x05 DSL

            0x06 - 0xFE Reserved

            0xFF Base Specification Use
"

Hi Fortune
The intent is to define an ANCP specific tech-type registry, and not take what MIP/PMIP uses as per your reference below.

Subject: [ANCP] Question about the Tech Type in draft-ietf-ancp-protocol-05

Hi all,

I have a question about the Tech Type in ANCP protocol for clarification.

It says "Tech Type" value of 0x05 SHOULD be used by ANCP for DSL technology in section 5.4.1.1 of draft-ietf-ancp-protocol-05.

I can find two related technology type registries at the website http://www.iana.org/protocols/ as follows, but the 0x05 has been allocated in both registries. Is the first registry with the name Access Technology Types the right registry for the Tech Type in ANCP protocol, please? If it is, I propose we change the 0x05 for DSL in section 5.4.1.1 to be 0x09 or "to be allocated by IANA"  in order to avoid incorrect implementation.
