Hi, all, I found this document to have useful context for discussion for the most part.
Some notes below: - it would be useful to provide a summary of the unique requirements of NVO3 that necessitate a new encapsulation protocol - there are many encapsulation issues not addressed, e.g., MTUs, frag/reassembly and fragment ID size, etc. - the discussion of TLV vs. bitfields needs a bit more expansion. E.g., TLV necessarily requires serial processing, whereas bitfields can be processed in parallel. - A "jump over" option is trivially possible in any TLV system, but begs the question of why the internal packet flow information needs to be examined (vs using the flow info in the outermost header). Why is this an NVO3 requirement? - TLV == bitfield for the first TLV field; i.e., TLV is a trivial way to extend bitfield to multiple bitfields if needed. That might be worth considering. - It might be useful to note that bitfields are much more difficult to handle optionally (e.g., it would require multiple bits, one for the value and several to tag the capability as "drop if not supported", "ignore if not supported", etc.). - I disagree with MUST support a minimum of 64 bytes of options; making that requirement effectively limits everyone to using only 64. IMO, that number is both too small and sets the protocol up to have "dead wood" (i.e., larger option space is specified but can't be relied upon so might never gain traction).
