Re: Consensus poll for IANA #409959 NAS-Port-Type value request

Regarding the below comments:

- Stefan comments that there’s already type for WiFi so not sure why another one is needed, just one.

- Klaas comments that agrees with Stefan’s comments.

- Nancy comments that looking at the current assignment is that there is only 1 allocation per mode.

Maybe it wasn't made clear why WiMAX requires these assignment. An email was sent recently and also this was discussed previously on the RADEXT reflector (See Nov. 2009).

Briefly:

The AAA in WiMAX is responsible to interact with various types of WiMAX NASes and also non-WiMAX NASes: The AAA thus needs to be able to determine which type of NAS it communicates with to determine the context of the Access-Request. WiMAX decided that it want an explicit indication of the type of NAS and hence wants to use the NAS-Port-Type to determine the context of the call.

The question is whether or not the NAS-Port-Type is the attribute to be used for that. The answer seems to be yes.

Second, the objection also seems to be based the number being requested. Is there a shortage of numbers? I don't think so. This was also discussed by the group in the past.

During IETF 80 one of the agenda topics discussed was whether to approve a request received by IANA for allocation of additional NAS-port-type values relating to Wimax as described below

Type of Assignment :
Nas-Port-Type values as follows:
TBD for WIMAX-3GPP-PRIF:  WiMAX Pre-Release 8 IWK Function
TBD for WIMAX-WIFI-IWK: WiMAX   WIFI Interworking
TBD for WIMAX-SFF: Signaling Forwarding Function  for LTE/3GPP2.
TBD for WIMAX-HA-LMA: WiMAX HA and or LMA   function.
TBD for WIMAX-DHCP : WIMAX DCHP service
TBD for WIMAX- LBS : WiMAX location based service
TBD for WIMAX-WVS : WiMAX  voice service

The snippet of meeting notes relating to this topic are show below:

---- <meeting note snippet begin>---------------------------

Request for registration for NAS-port-type. Under 3575, falls under expert review. This request is for NAS-port-type relating to WiMax
- Stefan comments that there’s already type for WiFi so not sure why another one is needed, just one.
- Klaas comments that agrees with Stefan’s comments.
- Nancy comments that looking at the current assignment is that there is only 1 allocation per mode.
- Bernard takes the general comment of only allocating one as the response to take back to the request. Given consensus here, will verify that opinion in the reflector.

---- <meeting note snippet end>---------------------------

The sentiment in the room was clearly against approving this IANA request and at this time we would like to confirm this on the mailing list.

Please respond to this email and state whether you are in favor or against approving this IANA request.

Thanks,
