reliable.io is a reliability layer for UDP protocols where there is a continuous bidirectional flow of packets.
It has the following features:
- Identifies which packets were received by the other side (acks)
- Packet fragmentation and re-assembly (send packets larger than MTU)
- Provides estimates for round-trip time and packet loss
IMPORTANT: It does not resend dropped packets. It simply tells you which ones got through!
