Hello, I've been on this list for some months now, but without a proper
introduction, so here goes:
My name is Frank de Bruin, I am working for the European Space Agency. The
last five years I have been working in several projects involving the use of
TCP/IP in satellite networks; mainly VSAT networks.
One of them was a study, carried out for us by the University of Aberdeen,
investigating the performances of various Internet protocols (main emphasis on
TCP) on satellite links. The Olympus satellite provided a perfect testbed for
crosschecking the results of simulations against the "real thing". We looked
at the relation of BER and throughput, link utilisation, etc..
Another major project was supporting the development (by the University of
Madrid) of a transputer based router. This IP router -supporting SNMP, ISDN
and multicast- integrates a satellite access protocol with the IP routing
function and implements a bandwidth sharing mechanism.
I was also involved in the design and installation of a global IP network
consisting of 16 nodes on both hemispheres. The nodes are different in size
and capabilities and are interconnected via a DAMA based satellite network (ie
dialup links). While the initial intention was to provide a limited set of
services (email, document distribution, faxing), it is now being reconfigured
to become more of an IP carrier.
At the moment, we are very much intested in systems/techniques that better
utilize the benefits of a VSAT network: broadcast nature, rapid deployment and
more flexible sharing of available bandwidth. Interesting topics for us are:
reliable multicast, receive-only stations (or hybrid systems with terrestrial
return), bandwidth modification and the applications that depend/make use of
these features.
