Various arrangements for monitoring and enforcing multi-tier throughput assignments in a network, such as satellite-based communication network, are presented. Throughput usage may be monitored on a beam-level, satellite-level, gateway-level, and system level. Throughput usage for individual satellite terminals may be aggregated and used to determine the throughput usage on an entity-by-entity basis. An entity can have one or more sub-entities to which throughput is allocated. Excessive throughput usage for higher-tier entities can result in throughput being restricted for satellite terminals associated with lower-tier entities.

Systems and methods provide load balancing on time division multiple access (TDMA) inroute channels of a satellite network. A bandwidth allocation manager or module can employ smart admission techniques to admit new terminals based upon the available bandwidth capacities of TDMA inroute channels including committed information rate (CIR) bandwidth requirements of already admitted terminals and current and CIR bandwidth requirements of the new terminals. Attempts are made to fully load a first TDMA inroute channel before providing admission to a second TDMA inroute channel. Additionally, an already admitted terminal requesting increased bandwidth or one or more other already admitted terminals may be reassigned to one or more alternative TDMA inroute channels to accommodate the requested increase in bandwidth.

A system is disclosed for centralizing common gateway operations in a satellite communication system. One or more distributed GWs establish a first Layer-3 connection to the plurality of terminals over a satellite network. A second Layer-3 connection is established between a data center and the distributed GWs over backhaul network. A network management system is provided for managing access to the external networks by the plurality of terminals. The system also includes a deep packet inspection unit, within the data center, for inspecting all traffic between the plurality of terminals and the external networks. The data center establishes a connection with external networks, and enable communication between the plurality of terminals and the external private networks. Multiple data centers can be used to balance traffic load, and to provide system redundancy.

A system and method for bandwidth management for a Host Network Operator (HNO) is disclosed. The method including: providing shared beams shared by two or more of a plurality of Virtual Network Operators (VNOs), wherein each VNO has a subscription including a global bandwidth limit applicable for a flow control epoch for each VNO and a terminal subscription for each terminal associated with the respective VNO; aggregating, in the current flow control epoch, a demand and the terminal subscriptions of active terminals per shared beam per VNO; distributing, for each shared beam per VNO, the aggregated demand and active terminal subscriptions into a distribution bandwidth per shared beam per VNO, wherein the distribution bandwidth is based on the respective global bandwidth limit of the respective VNO; and proportionally balancing, for each shared beam, an oversubscription of the distribution bandwidths per shared beam per VNO based on the proportionalities of the global bandwidth limit of each VNO subscribing to the shared beam, to provide a proportional distribution bandwidth per shared beam per VNO.

A broadband communication system with improved latency is disclosed. The system employs acceleration of secure web-based communications over a satellite communication network. In accordance with aspects of the invention, secure protocol acceleration is employed such that required protocol signals transmitted from a computer employing a web browser may be intercepted by a remote terminal. To insure that the browser will continue transmitting data, the remote terminal generates required acknowledgment and security signals to continue the secure communication, which may then transmitted back to the computer. Meanwhile, the received protocol signals may be converted by the remote terminal for transmission through the satellite communications system in a format appropriate for that communication medium. Aspects of the invention further include a hub or similar device for communicating with the satellite communications system.

Aspects of the invention further include a hub or similar device for communicating with the satellite communications system, and a secure connection between that device and the web server may be maintained by similarly simulating a continuous secure connection between the computer and the web server. Transmissions from the web server to the browser may be preformed in a similar manner. Further aspects of the invention related to distributed certificate sharing which may involve the generation of multiple certificates for the various links between the components employed in the communication system and the manual and/or automatic addition of a certificate authority.

A broadband communication system with improved latency is disclosed. The system employs distributed caching techniques to assemble data objects at locations proximate to a source to avoid latency over delayed links. The assembled data objects are then multicast to one or more remote terminals in response to a request for the objects, thus reducing unnecessary data flow across the satellite link.
