Fwd: RE: FW: General Request for Assignments (if-type) (Dost)


Just FYI --
Unless anyone raises any concerns or objections about these assignments in the next couple of days, I will tell IANA to go ahead and make these assignments. 

Thanks,
Margaret

Hi All,
This is not quite IPDVB-related, but this seems like the most likely place to reach DVB experts in the IETF...
Do you have any comments on the attached request that IANA allocate two if-type values for (apparently) DVB-related protocols? Particularly, do you have any thoughts on whether these are proprietary or industry standard protocols?
AFAIK, there is no problem with allocating these values, we are just trying to determine how they should be named.
Please include Bert Wijnen in any responses, as he may not be subscribed to the IPDVB list. 

Thanks!

Margaret
