Abstract

A two-way satellite communication system for providing a scalable architecture is disclosed. A plurality of transceivers transmit signals over a plurality of return channels, wherein the plurality of return channels are partitioned into a plurality of return channel groups. A hub communicates with the plurality of transceivers via the plurality of return channel groups. The hub is connected to a packet switched network. Each of the plurality of transceivers performs a random weighted selection of a return channel group among the plurality of return channel groups.
