    • A method for determining EIRP of user terminals in a satellite communication system comprises obtaining a frequency gain of a gateway at one or more frequencies, obtaining a path gain of the gateway for one or more signal paths, and obtaining a satellite beacon signal power at a receiver of the gateway. The method also comprises determining a target signal power at the gateway for one or more frequency channels, where the target signal power based at least in part on the frequency gain, the path gain, and the satellite beacon signal power. The method also comprises obtaining a message signal power at the gateway of a message from a user terminal, and determining the EIRP of the user terminal based at least in part on a difference between the target signal power and the message signal power.

    • Data transfer over an network is effected in a manner that facilitates the use of available communications channels and makes possible enhanced data routing control and monitoring. According to an example embodiment of the present invention, data is transferred over a network having a plurality of communication links. A home (e.g., data source) node coupled to the network supplies data for transfer on the network. A network-distributed application routing controller is implemented at a host server and at the home node, and is configured for controlling the home node for passing data on the network. A data request from a remote network access appliance, such as a laptop or mobile telephone, is received at the host server. In response to the request, the host server implements the network-distributed application routing controller to transfer data from a home node to the remote network access appliance.
