Abstract: A system and method for packing data over User Packets and packing the User Packets over DVB-S2 Frames, using the DVB-S2-ACM satellite transmission standard.

Abstract: A satellite data network may include one or more acceleration systems for acceleration data transfers through the network. The acceleration systems may spoof one or more protocols of a server to respond to requests from a client. One protocol that may be spoofed is the Common Internet File System (CIFS) protocol for communication across platforms having different file systems. The acceleration system may send data to the client or the server by maximizing usage efficiency of the bandwidth. The acceleration system may further cache information needed for responding to one or more requests so that it may respond to the requests without consulting the server. In one or more arrangements, a client side acceleration system and a server side acceleration system may be used concurrently to further enhance data transfer speeds and efficiency.

Abstract: An outgoing transmission carrier frequency at, for example, a remote terminal, may be adjusted based on a feature rate of an incoming transmission. The adjustment may compensate for error in the outgoing transmission carrier frequency. The incoming transmission may be from a satellite or hub, for example. The outgoing transmission may be the signal that is transmitted by an antenna, or the outgoing transmission may be converted to be at another carrier frequency such as a higher carrier frequency for ultimate transmission by an antenna. Also, a remote terminal may be synchronized to a satellite network with or without knowledge of the remote terminals' geographical location and with or without time stamps.

Abstract: The present invention relates to a system, device and method for two-way satellite communication using a dual channel communication configuration to make better use of limited bandwidth. The two channels include a dedicated Unicast channel for each remote VSAT terminal and a dedicated Multicast channel that is a shared resource for all the VSAT terminals in the network. Each VSAT terminal is provided with two separate tuners, one for Unicast information and one for Multicast information. The system thus provides Unicast information through the Unicast channel to the Unicast receiver in the VSAT terminal to individual destination VSAT terminals, and sends Multicast information to all VSAT terminals via the Unicast channel and the Unicast receivers in each VSAT terminal.

Abstract: A system and method for satellite based controlled ALOHA is provided. The system and method configure VSATs so that they accept guidance from a centralized and/or distributed system controller to determine when, where, and/or on what portion of a satellite resource to attempt to access a channel. The system and method take advantage of traffic patterns to maximize efficiency by utilizing a centralized and/or distributed control to determine which VSATs are and are not currently active, and to allocate to a portion of the inbound channel to the active VSATs and a portion of the inbound channel to the inactive VSATs. In a distributed approach, each VSAT decides for itself whether it captures a certain part of the inbound resource or not. This decision can be made based on previous transmissions that went through the part of the inbound intended to be captured.

Abstract: A flexible slotted Aloha communication protocol for a burst-type communication network divides a communication channel into a series of time cycles, with each time cycle further divided into contiguous time slices of identical duration. All data transmissions in the network begin at the start of a time slice and continue for an integer number of time slices, with the identity of the transmitting terminal, the length of the transmission and error correction, being included within the first time slice of each data transmission. Communication terminals in the network transmit reservation requests to a network hub which receives the reservation requests and reserves reserved time slots each having a number of time slices which matches the length of the data transmission to be transmitted in the reserved time slot. The reserved time slot may include time slices in more than one time cycle.
