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 satel= lite specific issues, such as fast mobility, frequent topology changes, con= straints in satellite power, security in open space, etc.
It is up to the community to decide what new technologies and what new prot= ocols will be developed.

Regards

Lin

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 solut= ion proposals may also come from different groups including research initia= tive SARAH.

Look forwarding to discussion and comments.

Thanks

Abstract:
=C2=A0 =C2=A0This document presents the detailed analysis about the problem= s and
=C2=A0 =C2=A0requirements of satellite constellation used for Internet.=C2= =A0 It starts
=C2=A0 =C2=A0from the satellite orbit basics, coverage calculation, then it=
=C2=A0 =C2=A0estimates the time constraints for the communications between<= br> =C2=A0 =C2=A0satellite and ground-station, also between satellites.=C2=A0 H= ow to use
=C2=A0 =C2=A0satellite constellation for Internet is discussed in details =C2=A0 =C2=A0including the satellite relay and satellite networking.=C2=A0 = The problems
=C2=A0 =C2=A0and requirements of using traditional network technology for =C2=A0 =C2=A0satellite network integrating with Internet are finally outlin= ed.
