摘要： A satellite communications system provides a communications service to a mobile terminal (2) on which different communications applications (4a to 4d) may be run. Calls are set up between any of the applications (4a to 4d) via a satellite (12) to a network management center (18) which provides different service adaptors (20a to 20d) which adapt the calls to different types of service provided over terrestrial networks (22), such as telephony, facsimile, internet or ATM services. The bandwidth allocated to each call over the satellite link may be varied during the call according to demand either from the relevant application (4) or from the network management center (18). Multiple calls may be connected concurrently to or from different applications running on the mobile terminal. A maximum bandwidth is allocated to each call. Efficient use is thereby made of the limited bandwidth available over the satellite (12), according to the instantaneous bandwidth requirements of different applications (4). For real-time calls requiring multiple slots per frame in a TDMA channel, the slots are mutually spaced apart to reduce delay.

摘要： A communications satellite (201) has an on-board high speed packet switch for switching transmitted data packets. The packet switch (502) is part of a processor subsystem (501) which also includes a number of demodulators (5031 to 503n) demodulating signals received from an uplink downconverter. All of the processors in the processor subsystem (501) are organized into a loosely coupled, distributed, architecture of general purpose computer modules (601) and digital signal processor modules (602) having both primary and redundant processors and being connected to each other by dual redundant PCI buses. Software and firmware is layered and distributed redundantly over the processor modules (601, 602).

摘要： A method for encoding network data, such as Internet Protocol (IP) data, into a format for transmission over a satellite system is described. The network data is configured in a packet having a data block and header information. The network data packet is encoded into a variable-length multi-packet transport (MPT) frame. The MPT frame comprises a data frame to hold data and header information. The IP packet in inserted its entirety into the data frame of the MPT frame. The variable-length MTP frame is then encoded into one or more fixed-length MTP packets. Each MPT packet has a data fragment block comprising a portion of the MTP frame and associated header information to designate what portion of the MTP frame is contained in the data fragment block. The MPT packets are sized to be embedded as a specific size payload of the satellite packet that is transmitted over a satellite network. Using this method, data received over a data network (i.e., Ethernet or Internet) in large network data packets are broken into smaller packets defined by the multi-packet transport. These smaller packets are then inserted as the data payload within standard fixed-size packets suitable for transmission across a particular distribution medium, such as satellite network. The network data remains independent of the underlying network and can be easily extracted at the receiver for use by computer applications.

摘要： A satellite communication system which performs switching on data cells. A switch (80) receives the data cells at a set of input ports (IP1-IP128) and directs them to a set of output ports (OP1-OP128). In order to arbitrate input data cells contending for the same output port, decision factor codes and routing codes are serially conducted to input registers (210), and a pseudo-random sequence code is appended. The combined codes are ordered by routing code in a decoder (220). The code with the highest decision factor code is selected in one or more determinators (230 and 240). The selected code is identified by a bit in a result register (250).

摘要： A method routes data packets between nodes in a satellite-based communication system based on header information contained in each of the packets. The header information which contains routing and overhead information indicates whether the packet header has been received without any errors and whether the payload is to be read and processed by the node currently servicing the packet or passed on to another adjacent node. This method works in systems that have packet delays or transmission impairments, such as satellite-based telecommunication systems.

摘要： In a global communication system that includes a constellation of satellite nodes that move with respect to each other, data packets are routed across communication links in a evenly distributed fashion. Uniform link usage is achieved within allowed routes determined by end to end transport delay criteria. The routing method computes routes in advance using an iterative process which selects routes for each source-destination pair from an allowed feasible set of alternative minimal hop routes by trying to equalize link usage probabilities for the links involved at each step of the route determination process. The routing method takes into account link failures and link and node shutdowns. Minimum hop routes are selected based on maximizing network routing entropy resulting in a uniform usage of the system's communication links. Directed randomization of routes between source-destination pairs of nodes is implemented to prevent link congestion while minimizing packet transport delay. Individual routing tables are generated and maintained in each satellite node. The tables may be updated regularly to reflect changes in the traffic demand distribution and the physical node connectivity within the constellation which occur as a result of satellite motion and failures in the network.
