- Description of Working Group:
-
- Satellites are being used to extend the Global Internet geographically
- and will be more ubiquitous in the next decade with the deployment of
- several proposed services capable of providing greater than T1 access
- to individual users anywhere in the world.
-
- Yet, satellite links have a unique combination of characteristics that
- can affect the throughput of TCP traffic. Because of the high-bandwidth
- delay product, slow start and congestion control algorithms behave much
- differently when the path includes a satellite link than exclusively
- terrestrial ones.
-
-
- The TCP over Satellite Working Group shall produce an informational RFC
- which describes the issues affecting TCP throughput over satellite
- links. It identifies the domains in which each issue applies, including
- network topology, satellite orbit (LEO, MEO, GEO), and link rates;
- fixes, both protocol and implementation, that ameliorate reduced
- throughput; and areas for further research. The purpose of including
- this information is to direct the research community to the areas in
- which show promise, not to perform the research or even advocate the
- results.
-
- Scope:
-
- The scope of this working group will include consideration of the
- following for inclusion in the Informational RFC:
-
- o Transport layer issues affecting TCP over
- satellite links
- o Existing TCP options
- o Compliant implementations which have some known
- improved performance over satellite links
- o Recommendation of well understood protocol changes
- o Identification of protocol changes that are potentially promising
- but require more further investigation in order to be well understood
-
- SECURITY
-
- The working group will consider in depth security issues that are
- relevant, describing risks and indicating how they may be addressed.
-
- Goals and Milestones:
-
- Jul 97 Post first Internet-Draft.
-
- Aug 97 Meet at Munich IETF to review Internet-Draft.
-
- Dec 97 Meet at DC IETF tyo achieve consensus on final version of
- Internet-Draft.
-
- Jan 98 Submit Internet-Draft to IESG for consideration as an
- Informational RFC.
