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 for
many other scenarios, including ad-hoc peer-to-peer communications,
delay-tolerant networking, 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.
