Interconnecting Danube Networks Through Satellite Links

Abstract

Local area networks (LAN) allow high speed communication and broadcasting.

Satellite communication systems will also offer high bandwidth transmission and broadcasting. Interconnection of LAN’s using satellite links looks promising. In order to gain experience in that field, the NADIR project studies and experiments the interconnection of LAN’s of the DANUBE type (developed by the KAYAK project) through satellite links, similar to those to be provided by the TELECOM 1 network.

The first experiments will use dedicated satellite links (both point to point and multipoint) to interconnect LAN’s assumed to belong to the same organization. Addressing and routing problems, particularly for multipoint, are discussed. It is then shown that hop by hop error control does not improve transmission quality, and that hop by hop flow control may not be necessary. A simple solution is presented.
