Multiplexing UDP-based protocols with QUIC January 2018, Melbourne
Multiplexing QUIC and RFC 7983 Problem: People want to use QUIC for things like WebRTC multiplexing with STUN, TURN and SRTP not using QUIC for RTP as in draft-rtpfolks-... 0-3 STUN 16-19 ZRTP 20-63 DTLS 64-79 TURN Channel 128-191 SRTP 2
Current spec Long Header Short Header Long header packet types use 127 and down Octet 0: 255 - 128 Collides with SRTP, can live with this 0-3 STUN 16-19 ZRTP 20-63 DTLS Short header types use 31 and down 64-79 TURN Channel Assuming C is 1 (CID always absent), 128-191 SRTP Octet 0: 127 - 64 Collides with TURN Channel, don’t care 3
Greasing Greasing applies to type field. Endpoint may grease more bits if it isn’t multiplexing with other protocols. (More in Martin’s presentation) 4
Decision Can we live with this arrangement? Caveat Emptor: These carve-outs are not invariant 5
