摘要： Some applications that cannot operate over a non-reliable delivery service may operate sufficiently well over less than a completely guaranteed delivery service. Such an application may perform relatively well even if some transmitted data is not delivered, as long as the application has information regarding which receiving entities received what part of the data. In a point-to-multipoint system, data may be transmitted from a source node to a plurality of destination nodes using a plurality of multicast datagrams. Methods are presented herein for efficiently enabling the source node to determine for each of the plurality of destination nodes which multicast datagrams were successfully received. Also presented are methods for compressing data transmitted from the source node to the destination nodes, wherein a compression dictionary is transmitted from the source node to the destination node using multicast datagrams.

摘要： 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.

摘要： A single, large-scale satellite access communication network may be configured as infrastructure for many small-scale subnets, wherein each subnet may be configured to serve a different organization (e.g. an SME) as a private network. Each subnet may be configured as a small star and/or mesh satellite data access network from the end-user perspective, yet all subnets may be configured to be part of the total large-scale network and share satellite bandwidth resources. Such configuration may yield significantly higher bandwidth efficiency, lower operation and equipment costs, minimized latency and ease of network operations for each of the small organizations sharing the large-scale network.
