gnuTLS community

videoLAN community


Based on..

Mirko Palmer, Thorben Kruger, Balakrishnan Chandrasekaran, Anja Feldmann, The QUIC Fix for Optimal Video Streaming

Colin Perkins, JÃűrg Ott, Real-time Audio-Visual Media Transport over QUIC

What is QUIC?

Head of line blocking

How performant is QUIC?

Web loads 8% faster than TCP


Streaming is 20% faster than TCP stack

Google says...

Background for QUIC on Streaming!

  • streaming is taking up more and more of global internet traffic: >75%
  • Performance over TCP is not great
  • High latency: application and transport impact with MPEG DASH

  • Mainly head of line blocking due to reliable transport

Background for QUIC on Streaming!

  • QUIC helps, but not much
    • Still has per-stream HOL blocking

    • Still high latency

What's proposed...?

QUIC TLS API for crypto in gnutTLS

In gnuTLS...

What's proposed...?



In VLC....?

What's proposed...?


What's proposed...?

In  Custom QUIC extension (QUIC-tweaked) ....?

  • Selective Reliable Transport

  • Deadline Awareness

  • Message-Oriented Abstraction

  • Forward Error Correction

  • I-P-B frame handling

  • Head-Of-Line blocking resilience

What's proposed...?

RTP over QUIC-tweaked

DASH over QUIC-tweaked

In  VLC with tweaked QUIC ....?

What's proposed...?



Exposing QUIC TLS APIs in gnuTLS

  1. A callback to notify the key (epoch) change
  2. A callback to write a Handshake messsage, when it is being sent
  3. A callback to write an Alert messasge, when it is being sent
  4. A callback to flush the message.
  5. A function to push data received from the peer to the TLS layer


HTTP POST support in VLC

  • Need a single connection to POST data, since we won't get proper response for a POST request compared to GET.
  • Fix for the idenpotency implementation.
