Re: [quicwg/base-drafts] Consistent presenting Connection ID in packet or frame (#1336)

[MikkelFJ <[e-mail]>]

I was thinking a bit about using a single port also for the client case:

In this case the number connections is likely small, but a CID cannot be zero length. Using a full byte to encode CID length is a bit much if you only need to distinguish between 8 different CIDs.

At the same time, if CID's are tied to key rotation, 0 length CID's won't work but a single bit CID would work similar to a key phase, iff CID's can be reused in this case.

If the minimal CID length, including length prefix, is a single byte, there isn't much space left for longer, but it can be handled:

Two bits code for length. 00, 01, 02, 03

00: keyphase, zero length CID, but a single keyphase bit.
01: 6 bit bit CID
02: 14 bit CID
03:  CID length is encoded in the following 6 bits.
