"Internet Protocols over Satellite" (IPoS) is the concise name for the TIA-SCD-CIS-Internet Protocols Working Group (TR34.1.1)--a working group within the Telecommunications Industry Association-Satellite Communications Division (TR43)-Communications and Interoperability Section (TR43.1).

The group is concerned with developing enhancements to Internet protocols to facilitate seamless integration of satellites into the Internet topology.

The working group co-chairs are:

- Aaron Falk (Aaron.Falk@trw.com)
- M. Scott Corson (corson@isr.umd.edu)

Selected Snippets

• Aaron's minutes of January 30, 1997 meeting at NASA Lewis Research Center.
• Directions to Tim's cool TCP plotting stuff.

TCP-related Working Groups

• TCP Large Windows (tcplw) working group formed within IETF.
• TCP Implementation (tcpimpl) working group formed within IETF (list archive).

To support work on TCP enhancements, a "TCP-over-satellite" mailing list 
has been created.

To access it send email to:
    majordomo@listserv.trw.com

with the following in the body of the message:
    subscribe tcp-over-satellite

To send mail to the group of registered users send mail to:
    tcp-over-satellite@listserv.trw.com

An attempt is being made to archive the list here at UMD, 
but it is not yet working (the listserv at TRW is behind a firewall).

Satellite-related Working Groups

• Uni-Directional Link Routing (udlr) working group formed within IETF.
