Title : Saratoga: A Convergence Layer for Delay-Tolerant Networking
Author(s) : L. Wood, et al.
Filename : draft-wood-dtnrg-saratoga-01.txt
Pages : 43
Date : 2007-7-8
Saratoga is a simple, lightweight UDP-based transport protocol
intended for use in moving files between immediately neighbouring
peers which have sporadic, intermittent connectivity using dedicated
IP links. Saratoga focuses on high link utilization for fast file
transfers. Loss recovery is implemented via a simple ARQ mechanism.
Saratoga is proposed for use as a convergence layer by Delay-Tolerant
Networking for deep-space and ad-hoc networking scenarios.
Saratoga is not intended for use over shared paths, so transport
congestion control is unnecessary, although it could be optionally
implemented at the sender to provide rate control of packet output.
Saratoga is in continuous operational use by the IP-based Disaster
Monitoring Constellation satellites in Low Earth Orbit (LEO) for
mission-critical transfer of remote-sensing imagery.

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.
