摘要： An approach for allocating bandwidth is disclosed. A request is detected from a terminal for capacity on a communication channel based on type of traffic transmitted from the terminal. A bandwidth allocation pattern designated for the terminal is retrieved, wherein the bandwidth allocation pattern is set based on a predetermined service plan associated with the terminal. Bandwidth over the communication channel is reserved for the terminal according to the bandwidth allocation pattern without feedback to the terminal. This arrangement has particular applicability to a satellite network that provides data communication services.

摘要： A method of providing a high symbol rate communication system with reduced overhead bandwidth includes calculating a minimum feasible aperture length at a network operations center, setting a hub demodulator subsystem to use an aperture length calculated from the minimum feasible aperture length, broadcasting the aperture length to a VSAT, and receiving an inroute data stream from the VSAT utilizing the aperture length.

摘要： This disclosure relates to the transmission of binary data over a network between a transmission host and a receiving host. The transmission host receives packets of data including data in a first format which may be ASCII formatted and contain 6 bits-per-byte words, and including data which had an original binary format containing greater than 6 bits-per-byte words (such as 8 bits-per-byte) and which has been encoded (such as Uuencoded) to 6 bits-per-byte words. The transmission host searches the packets and identifies the encoded data and reverse codes the encoded data to its original binary format, before transmitting the data on a suitable network transmission media that can transmit both ASCII formatted data and data having greater than 6 bit-per-byte formats. The transmission host also includes an application packet demultiplexer for separating the incoming data according its application such as HTTP, NNTP, FTP, etc. The transmitting host includes an identifier in the packets for identifying the reverse coded data. The receiving host responds to the identifier and may encode the previously reverse coded data.

摘要： An approach is provided for shaping traffic of a communication system. Resource usage of a network element of the communication system is determined. The usage is compared with thresholds that are established according to loading of the communication system; these thresholds correspond to various transmission states that limit usage of the resources of the communication system (e.g., bandwidth). Further, based on the comparison, the resource usage of the network element is controlled according to a particular transmission state, thereby ensuring fair access. This approach as particular applicability to shared capacity systems, such as a satellite communication system.

摘要： An approach is provided for supporting a fair access policy to exchange traffic in a radio communication system. A committed information rate (CIR) level is assigned to a terminal according to one of a plurality of throttling states that specify respective different throughput levels according to loading of the communication system. The traffic is forwarded to the terminal based on the current throttling state of the terminal, wherein the traffic throughput is limited to the CIR level of the terminal. This approach as particular applicability to shared capacity systems, such as a satellite communication system.
