[Rmt] RE: [EXP2STD] IANA Registries for LCT Header Extentions ?



All,

 

Another possibility which has been suggested to me is to have a single flat registry (introduced by LCT) and abandon the PI-specific header types idea. So, for example, LCT Header Extension 64 would mean the same in all PIs, rather than having the possibility for 64 to mean different things in different protocols that use LCT.

 

I think this would be simpler (and there are no backwards compatibility issues).

 

If you disagree, please disagree *soon*, otherwise that’s what will appear in the draft!!

 

Regards,

 

Mark

Subject: [EXP2STD] IANA Registries for LCT Header Extentions ?

 

All,

 

In updating the LCT and ALC documents for Standards Track, I have come again across the fact that there is no process defined for specifying new LCT Header Extensions.

 

LCT divides the LCT Header Extension Type range into two parts, a general part and a PI-specific part. LCT then defines two general LCT Header Extensions (EXT_NOP and EXT_AUTH).

 

ALC goes on to define an ALC-specific LCT Header Extension EXT_FTI. FLUTE defines two further ALC-specific extensions EXT_FDT and EXT_CENC.

 

I think we should have IANA registries for these: a registry for the general LCT header extensions (which would be established in the ‘IANA Considerations’ of LCT) and registries for the PI-specific header extensions (one for each PI, established by the ‘IANA Considerations’ of each PI specification).

 

Comments ? What should the allocation rules be ? “IETF Consensus”, “Specification Required” ?

 

Regards,

 

Mark
