Title : A TCP Test to Allow Senders to Identify Receiver Non-Compliance
Author(s) : T. Moncaster, et al.
Filename : draft-moncaster-tcpm-rcv-cheat-01.txt
Pages : 31
Date : 2007-6-7
The TCP protocol relies on receivers sending accurate and timely
feedback to the sender. Currently the sender has no means to verify
that a receiver is correctly sending this feedback according to the
protocol. A receiver that is non-compliant has the potential to
disrupt a sender's resource allocation, increasing its transmission
rate on that connection which in turn could adversely affect the
network itself. This document presents a two stage test process that
can be used to identify whether a receiver is non-compliant. The
tests enshrine the principle that one shouldn't attribute to malice
that which may be accidental. The first stage test causes minimum
impact to the receiver but raises a suspicion of non-compliance. The
second stage test can then be used to verify that the receiver is
non-compliant. This specification does not modify the core TCP
protocol - the tests can either be implemented as a test suite or as
a stand-alone test through a simple modification to the sender
implementation.

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
