 The point is that each type C LSE contains 32 bits, of which 19 bits are dedicated to ancillary data.  If they are not carrying ancillary data they are unused but still transmitted.  So, unless they are re-purposed, your proposal doesn't buy anything.

 I do not really understand your question. Could you please give me more information?

Let me try to answer. Type c can have data. What l want to do is to reduce the redundant information when there are more than one actions.

Hi John,

One packet may need multiple actions/opcodes.
The group format will indicate several actions can share the same metadata.

So, for what are the post opcode bits in each of the subsequent format C LSEs used?

Hi WG and Authors,

 

This draft proposed the 4 LSE formats with sequence: A-B-C-D.

I want to propose a new LSE format. Let’s call it C’ temporarily.

C’ is a kind of group, which can group several C formats.

So the sequence is A-B-C’-C-D.

 

This format can reduce the redundancy of several LSEs.

For example, if several LSEs have the same flow id, we can just put this flow id at the beginning of the group. And all the following LSEs in this group can use.

 

Best,

Tianran
