Not for a RG :-) It could be populated entirely by graduate students doing interesting tests in simulated environment using modified off-the-shelf (i.e. already RFC) routing protocols. And then writing papers, with the modifications written up as I-Ds. I know RPL (RFC6550) quite well, and it has useful properties for space. (Like, if a link-fails-in-the-forest, but nobody had any data to send, then the link never failed). I wouldn't want to use OSPF for this. What it doesn't have is anything about motion: i.e., expected link failures. I could see an attribute (a metric) which told of the sender's expected motion, specifically towards or away from the receiver, and then this needs to be correlated with occultations. That would let the network do make-be= fore-break. I think that there are potentially many ways to do this; maybe it's already been done. =2D- Michael Richardson . o O ( IPv6 I=C3=B8T consulti= ng ) Sandelman Software Works Inc, Ottawa and Worldwide --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQFKBAEBCgA0FiEEbsyLEzg/qUTA43uogItw+93Q3WUFAmfKM5UWHG1jcitpZXRm QHNhbmRlbG1hbi5jYQAKCRCAi3D73dDdZfgeB/sFkcEf/Coa68ntHMAI6VhcDfU0 gdq8a1ynFbOXTbz7bHLYMGwccCDSK5pcSfNv4KMM4euKUUp7MLluUGQoLGTjDyV4 kWIft+vpTGtgDSUxLWHjxUkWmS00/IeC7y0zmZbRvw7F1Ri6S1am5ZZxsSNXRiDw CETfaCX48Zj7w/tpawh9ErA1fxQLEow+i9fYEj3tasZToEm1b2JUeKh7/WIjkMgg RTfRoUk4rtSO3DEAxUo27NFKqKQhXDybKyN7Dis3ijyxTp6sW0ngUOriQvnFLHgc SDhXRA5wTUsH8j8T6fBwO6HJY6sjWQS8NB9XSs3Z8BABgNpyLGw5spsFWkrE =SBJm -----END PGP SIGNATURE----- --=-=-=--
