Abstract:
This document specifies the Saratoga transfer protocol. Saratoga was
originally developed to transfer remote-sensing imagery efficiently
from a low-Earth-orbiting satellite constellation, but is useful in
many other scenarios, including ad-hoc peer-to-peer communications,
large-scale scientific sensing, and grid computing. Saratoga is a
simple, lightweight, content dissemination protocol that builds on
UDP, and optionally uses UDP-Lite. Saratoga is intended for use when
moving files or streaming data between peers which may have
permanent, sporadic or intermittent connectivity, and is capable of
transferring very large amounts of data reliably under adverse
conditions. The Saratoga protocol is designed to cope with highly
asymmetric link or path capacity between peers, and can support
fully-unidirectional data transfer if required. Saratoga can also
cope with very large files for exascale computing. In scenarios with
dedicated links, Saratoga focuses on high link utilization to make
the most of limited connectivity times, while standard congestion
control mechanisms can be implemented for operation over shared
links. Loss recovery is implemented via a simple negative-ack ARQ
mechanism. The protocol specified in this document is considered to
be appropriate for experimental use on private IP networks.
