Re: [tsvwg] Advance notice on request to poll TSVWG for adoption of draft-kaippallimalil-tsvwg-media-hdr-wireless-03

Hi all,

What if, instead of implementing network options 
piecemeal as UDP options, there were instead defined a UDP option which
just encapsulates the whole HBH  extension header, to get it past nodes that
would drop it?

This would have the following advantages:

- rather than taking away energy from getting HBH options to work, it would
add to it.

- The spec for this 'HBH header encapsulation  option' could recommend that
network nodes which processes HBH options inside  it, SHOULD also process the 
same options if found in an unencapsulated HBH extension header. In this way,
those nodes would be ready if  HBH options end up being transmissible over the
internet.
 
- It would consume only one UDP option type, instead of one per function. All
 'network options' would be enumerated in one place, in the HBH options list.

- If the HBH header sees greater  use in this way, it would provide an 
argument for enabling  it to pass unencapsulated.

NB I don't specifically have an opinion on  whether the media header should be an HBH
option. But if it should be, maybe this is a useful way of resolving the difficulty of
avoiding packets containing it being dropped.
