The Eifel Response Algorithm for TCP
RFC 4015, “The Eifel Response Algorithm for TCP”, is a Proposed Standard document published in February 2005 by R. Ludwig, A. Gurtov. The canonical text is published by the RFC Editor.
Abstract
Based on an appropriate detection algorithm, the Eifel response algorithm provides a way for a TCP sender to respond to a detected spurious timeout. It adapts the retransmission timer to avoid further spurious timeouts and (depending on the detection algorithm) can avoid the often unnecessary go-back-N retransmits that would otherwise be sent. In addition, the Eifel response algorithm restores the congestion control state in such a way that packet bursts are avoided. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
