A userspace reliable transport protocol whose congestion window is governed only by the delivery rate (i.e., bandwidth/throughput) and the data loss rate.

  • main entry: [[src/transport_layer.rs]]
• a user-facing I/O-agnostic socket wrapper
  • managing opening, closing, timer, async read/write for the transport layer
  • perk: You are allowed to wait until or check if the send buf is empty!
