Abstract
In response to call requests from a source data terminal, a source earth station establishes first logical channels between it and the source data terminal and establishes logical links from the first logical channels to destination earth stations via a communications satellite. The destination earth stations establish second logical channels from the logical links to the destination data terminals. Each earth station performs flow control on each of the respective logical channels on a per message unit basis and performs flow control on each of the logical links on the basis of per plural consecutive message units to provide high throughput on the satellite channel.
