Title : The Eifel Algorithm for TCP
Author(s) : L. Reiner
Filename : draft-ietf-tsvwg-tcp-eifel-alg-02.txt
Pages : 10
Date : 21-Nov-01
A solution to eliminate the retransmission ambiguity in TCP, is to
mark ACKs with a special retransmit-marker. The marker would need to
be present in those ACKs, and only those ACKs, that the TCP receiver
sends in response to retransmits; both genuine and spurious
retransmits. Based on such a retransmit-marker, the Eifel algorithm
allows the TCP sender to detect a posteriori that a fast retransmit
or a timeout was spurious. Three alternative retransmit-markers are
defined in this document, and the Eifel algorithm may be based on
either one of them: the TCP RXT flag, the TCP Timestamps option, and
the TCP SACK option. The Eifel algorithm provides a basis for future
TCP enhancements such as response schemes that may change a TCP
sender's protocol state to improve end-to-end performance.

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.
