Title : The Eifel Response Algorithm for TCP
Author(s) : R. Ludwig, A. Gurtov
Filename : draft-ietf-tsvwg-tcp-eifel-response-04.txt
Pages : 11
Date : 2003-10-30
The Eifel response algorithm requires a detection algorithm to detect
a posteriori whether the TCP sender has entered loss recovery
unnecessarily. In response to a spurious timeout it adapts the
retransmission timer to avoid further spurious timeouts, and can
avoid - depending on the detection algorithm - the often unnecessary
go-back-N retransmits that would otherwise be sent. Likewise, it
adapts the duplicate acknowledgement threshold in response to a
spurious fast retransmit. In both cases, the Eifel response algorithm
restores the congestion control state in such a way that packet
bursts are avoided.

In the body type:

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
