Hi, Stewart,

What does "LI" stand for?
ISL is not mature enough for real adoption.
The academia research suggested to use laser instead of microwave. When laser is used for ISL, there should not have spectrum license issue, I don't see the ITU or USA has spectrum allocation for the frequency of laser (400THz~700THz).

The thing that worries me about iSL is whether the inability to do LI will prohibit licensing in some countries.

Mark Handley published the paper "Using ground relays for low-latency wide-area routing in megaconstellations" to show that even if we do not have ISL we can use ground terminals to route traffic with better latency than fiber links.

Hi, Jim

I don't have clear answer.
What I can guess now is that most of current technologies (with enhancement) can be used, but some new technologies might be needed to solve the satellite specific issues, such as fast mobility, frequent topology changes, constraints in satellite power, security in open space, etc.
It is up to the community to decide what new technologies and what new protocols will be developed.

Regards

Lin

Lin,

        Are you suggesting that the current set of protocols can be used with or without enhancements or is the uniqueness of the satellite network require new protocol(s) to address the architecture you have laid out..

Thanks,

Hi,

This draft analyzed the problems and requirements for the satellite network when it is integrated with Internet by current routing technologies.
It may be relevant and interesting to internet, BGP, IGP. The further solution proposals may also come from different groups including research initiative SARAH.

Look forwarding to discussion and comments.

Thanks

Lin

Abstract:
   This document presents the detailed analysis about the problems and
   requirements of satellite constellation used for Internet.  It starts
   from the satellite orbit basics, coverage calculation, then it
   estimates the time constraints for the communications between
   satellite and ground-station, also between satellites.  How to use
   satellite constellation for Internet is discussed in details
   including the satellite relay and satellite networking.  The problems
   and requirements of using traditional network technology for
   satellite network integrating with Internet are finally outlined.
