Abstract: A network having known network parameters is evaluated based on determined network capacity, utilization, and efficiency attributes relative to different traffic constraints and routing constraints applied to the known network parameters. Each of the network capacity, utilization, and efficiency attributes have prescribed definitions based on the network parameters and relative to the different traffic constraints and routing constraints, and are determined based on linear programming computations of the respective prescribed definitions and the network parameters. The network capacity, utilization, and efficiency attributes can then be applied to computer-based optimization resources configured for determining optimum network parameters for the network.

Abstract: A system and method for optimizing a network design to obtain an optimized network design relative to a desired network capacity. The network design has an initial traffic distribution and is evaluated based on a determined network capacity, network traffic values, and anticipated growth rates bounded by a prescribed growth deviation factor. An optimized traffic matrix is determined using linear programming resources, relative to a maximum capacity for the initial traffic distribution and based on the determined network capacity, the network traffic values, the anticipated growth rates, and the prescribed growth deviation factor. The optimized traffic matrix entry having a minimum growth rate is identified, and link capacity is added based on the entry having the minimum growth rate.

Abstract: In a satellite network with on-board switching and bandwidth on demand, traffic monitoring is required to facilitate billing data collection and to avoid congestion at the satellite. In addition to traffic monitoring, performance monitoring is necessary to quickly respond to link degradation or possible equipment anomalies. Monitoring terminals specially equipped with traffic measuring and policing and link performance measuring capabilities are used to monitor traffic and performance. The monitoring terminal is located in each satellite beam to perform the monitoring functions for that beam. The monitoring terminals are low-cost terminals that receive down-link traffic in their respective beam, and record statistics on a per transmit-terminal or per virtual connection basis. Records are periodically transmitted to a central location where they are processed for billing, enforcing traffic contracts, and taking actions against link degradations.
