    Admission Control Schemes for Spot-Beam Satellite Networks
    (1993) Ramseier, S.; Ephremides, Anthony; ISR; CSHCN
    In this report, we consider communication networks with a satellite with multiple spot beams. We describe the structure and features of these networks, and we consider admission control schemes which optimize the network revenue if several services types with different revenues are present. We show that in some cases the blocking of some calls even if capacity is available can considerably increase the network revenue. We will point out, however, that complete sharing, i.e., accepting calls on a first- come, first-served basis, is optimum for systems with similar traffic types.

    LAN Interconnection by Satellite --- A Literature Review
    (1993) Ramseier, S.; ISR; CSHCN
    In this report we give an overview on experiments interconnecting LANs by satellite, which are reported in the technical literature. Most reported scientific experiments have been performed in Europe and Japan, whereas in the USA a more application oriented, commercial approach seems to have been taken. In this report, we briefly describe several projects, such as the French NADIR, the European STELLA, UNIVERSE and SATINE-2, some experiments performed by the European Space Agency ESA, such as PRODAT and CODE as well as a special internetworking experiment. We also mention some Japanese and a Canadian project.
