[Sis-SCPS-INTEREST] SCPS-TP actually in use?

[Scott,Keith L.]

John,

To date, most deployments of SCPS-TP have been in the form of
performance enhancing proxies (PEPs) to improve
terrestrial-to-terrestrial TCP performance over satellite links.  There
are a number of commercial companies offering SCPS-TP-based proxies:

XipLink: http://www.xiphos.ca/xiplink/index.html
SkipWare: http://www.skipware.com
Bandwidth TurboBooster: http://www.hotlens.com/products/index.html
NetAcquire Server: http://www.netacquire.com/SCPS.htm

Packeteer version 5.0 Mentat/SkyX:

The story of the commercial spinoff of SCPS (and the original role of
Global Protocols) is documented at:
http://www.sti.nasa.gov/tto/Spinoff2004/ct_1.html.

Also of note is the plan by the SATLABS consortium in Europe to
standardize the SCPS-TP for use across the Digital Video
Broadcasting-Return Channel Service (DVB-RCS) satellite link as a
"performance enhancing proxy" to handle the link characteristics when
providing broadband Internet to the home. The DVB-RCS development
follows on the heels of the recent selection of SCPS by the US-DOD as
the baseline for MILSATCOM's Standardized Tactical Entry Point
(STEP)/Teleport sites.

There just hasn't been much of a requirement up to now to run TCP to
endpoints in space, though SCPS-TP has been used to do this
experimentally.  This may change with the international push (NASA,
ESA) to return to the moon and to land humans on Mars.  If this does
occur, use of SCPS-TP may well be in the form of PEPs so as to not
require modification of end stacks.
