Hello Jonathan:

We discussed that an it confused folks. So it was removed from the last draft.
Clearly the proposal 3.2 eliminates a capability to use RFC 4944 stuff after the page is passed.
If we wanted to restore that, we’d define a page for RFC 4944 that is implicit today.
I’m not saying that this is better than your proposition since IMHO it is not.
But I want to clarify what’s on the table…

Cheers,

Pascal

For example, only define two types of headers (elective and critical) and only use a single bit to distinguish between them.  Then cast everything (including RFC 4944 and RFC 6282) within those headers.  For example, don't bother to reserve 00xxxxxx for something else.


>    Why bother casting 4944 stuff? It is already on page one. Could you clarify?
What if I want to use the same 6loRH header to source route individual 6lo fragments?  Yes, doing so incurs the overhead of source routing on each fragment, but then there is no need to reassemble at every hop and allows sending fragments along different paths.
