Packet Loss Detection Based On Recent Acknowledgement (Rack), Yuchung Cheng, Neal Cardwell
Defensive Publications Series
This disclosure describes techniques for packet loss detection in networks based on Recent ACKnowledgement (RACK). RACK technique uses the notion of time, instead of conventional approaches for packet loss detection such as packet or sequence counting.
