QUIC in Space

   - Champion(s)
      - Marc Blanchet (marc.blanchet at viagenie.ca)
      - Christian Huitema (huitema at huitema.net)
   - Project Info
      - (Deep) Space comm has loooong delays (minutes to hours) and
      disruptions. Purpose of the project
      is to modify open-source QUIC stacks to be usable for this use case.
      QUIC stacks typically
      have low initial values to prime the initial communications, which
      does not fit with long delays
      and make various assumptions not optinal for space comm. Goal of this
      project is to:
      a) externalize these static values so they could be changed at start
      or while running,
      b) set a testbed to test with long delays and verify use
      c) modify stacks to support the space use case (specially for
      disruptions), d) if relevant,
      write internet-draft for findings and possible
      modifications/extensions to QUIC.
      An initial POC was done with Christian Huitema (see below) with his
      picoquic stack.
      We would like to go further with more QUIC stacks such as Mozilla
      Neqo (in Rust) or
      Google Quiche(in C++) or Cloudflare Quiche (in Rust) or picoquic(in
      C) or QUINN (in Rust).
