Title : CUBIC for Fast Long-Distance Networks
Author(s) : I. Rhee, et al.
Filename : draft-rhee-tcpm-cubic-00.txt
Pages : 20
Date : 2007-8-30
CUBIC is an extension to the current TCP standards. The protocol
differs from the current TCP standards only in the congestion window
adjustment function in the sender side. In particular, it uses a
cubic function instead of a linear window increase of the current TCP
standards to improve scalability and stability under fast and long
distance networks. BIC-TCP, a predecessor of CUBIC, has been a
default TCP adopted by Linux since year 2005 and has already been
deployed globally and in use for several years by the Internet
community at large. CUBIC is using a similar window growth function
as BIC-TCP and is designed to be less aggressive and fairer to TCP in
bandwidth usage than BIC-TCP while maintaining the strengths of BIC-
TCP such as stability, window scalability and RTT fairness. Through
extensive testing in various Internet scenarios, we believe that
CUBIC is safe for deployment and testing in the global Internet. The
intent of this document is to provide the protocol specification of
CUBIC for a third party implementation and solicit the community
feedback through experimentation on the performance of CUBIC. We
expect this document to be eventually published as an experimental
RFC.

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
