Implementation
In order to ensure quality, it extends UDP by means of adding the following features:
- Acknowledgment of received packets
- Windowing and flow control
- Retransmission of lost packets
- Overbuffering (Faster than real-time streaming)
RUDP is not currently a formal standard, however it was described in an IETF internet-draft in 1999. It has not been proposed for standardization.
