摘要： A satellite communication system includes a communication terminal and a ground station. The ground station is configured to communicate with the communication terminal through a satellite communication path between the ground station and the communication terminal via a satellite. The ground station includes a diversity switch and an electronic controller. The diversity switch is configured to switch the satellite communication path from a first satellite communication path to a second satellite communication path different from the first satellite communication path. The electronic controller is configured to transmit an offset value of network parameters of the first and second satellite communication paths to the communication terminal through the second satellite communication path. The communication terminal is configured to update a propagation parameter for communication with the ground station based on the offset value in response to receiving the offset value through the second satellite communication path.

摘要： An apparatus, system, and method for balancing traffic loads on beam outroutes that contain both multicast and unicast traffic. An outroute is designated for supplying at least multicast traffic within a beam of a satellite communication system. Terminals interested in receiving the multicast traffic are moved to the designated outroute. Traffic loads on all outroutes within the beam, including the designated outroute, are compared to determine if variations in the traffic loads exceed a predetermined threshold. A load balancing routine is performed to redistribute the traffic loads on all outroutes, while excluding any terminal that is actively receiving the multicast traffic from the load balancing routine.

摘要： A system and method for improving proxy server performance in a communication network. The system and method employ a proxy server configured to, in response to a request identifying a domain name, determine whether domain name resolution information associated with the domain name is stored in a storage accessible by the proxy server and has exceeded an expiration time for the domain name resolution information, provide the domain name resolution information from the storage in response to the request via the network upon determining that the domain name resolution information is stored in the storage, has exceeded the expiration time and meets a delivery condition, and request from a domain name server updated domain name resolution information upon determining that the domain name resolution information is at least one of absent from the storage and has exceeded the expiration time.

摘要： An apparatus is disclosed for delivering layer-2 services over a layer-3 network. The apparatus includes a layer-2 module for transmitting and receiving layer-2 packets over a first communication network, and a layer-3 module for converting the layer-2 packet into a format that can be transmitted over a conventional layer-3 network. The converted layer-2 packet is transmitted with sufficient information to allow reconstruction of the original layer-2 packet at the destination device. The apparatus can also be configured to simultaneously transmit and receive layer-2 packets and layer-3 packets over the layer3 network.

摘要： A process for improving network performance in systems that utilize secure domain name system (DNS) schemes. Encrypted DNS requests from devices in a local area network (LAN), such as a home or office, are submitted to a local proxy which stores cached DNS records. The proxy decrypts or examines at least a portion of the DNS request in order search for a matching record in its storage. Matching records are retrieved, encrypted, and supplied to the requesting device to satisfy the DNS request. If the proxy does not contain a matching record, the DNS query is encrypted and submitted to an external DNS server for resolution. The matching record can optionally be saved by the proxy prior to being supplied to the requesting device.

摘要： A communications terminal comprises data interface, a transport selection processor and a plurality of communications modems. The data interface receives input data from application sessions for transmission over a data communications network. Each of the application sessions imposes respective transmission requirements for transmission of the data over the data communications network. Each of the communications modems transmits the input data over the data communications network via a respective transmission platform, wherein each transmission platform exhibits respective transmission characteristics based on a transmission technology of the transmission platform. The modems are configured to transmit the input data simultaneously. For each of the application sessions, the transport selection processor selects a one of the modems, for transmission of the input data of the respective application session over the data communications network, based on the respective transmission requirements of the application session and the transmission characteristics of the respective transport platform.

摘要： An approach is provided for the application of network acceleration technologies to remote node traffic over GPRS tunneling protocols (GTP) in terrestrial mobile communications networks. A proxy device of a first network node receives a stream of data packets that are encapsulated in accordance with GTP. Each GTP packet is de-encapsulated by stripping GTP header from the packet, identifying the TEID (reflecting a respective GTP flow with which the GTP packet is associated), and maintaining a respective GTP payload (PDU). Acceleration functions are applied to the GTP PDUs, and the resulting acceleration packets are transmitted communications network link(s) to a proxy of a second network node. The second node proxy device receives the transmitted packets, and re-encapsulates each packet, in accordance with the GTP protocol, based at least in part on the respective TEID of the packet.

摘要： A system and method for improving network performance of DNS queries. The system includes a terminal which receives DNS queries from a customer premise equipment (CPE), and supplies matching DNS records in response to the queries. The terminal monitors all traffic from the CPE and generates a preload list containing domains and a time schedule at which name resolution should be requested for the domains. A DNS preload client in the CPE receives the preload list from the terminal, and submits preload DNS queries for name resolution of domains contained in the preload list at times specified in the time schedule. Preload records supplied in response to the preload DNS queries are stored by the CPE and used to resolve DNS queries from applications installed on the CPE.

摘要： A system and method for association of remote nodes with respective aggregation nodes in a high capacity shared bandwidth communications network, is provided. A gateway receives an association request message from a terminal device, wherein the association request message includes a service signature and service parameters of the terminal device. The gateway determines whether the association request message reflects a valid request based on the service signature. The gateway determines service requirements of the terminal device, based on a correspondence between the service parameters and associated information of a service requirement database of the gateway. The gateway determines whether it is configured for servicing the service requirements of the terminal device. The gateway transmits an association accept message, including one or more association parameters.

摘要： A method and system for automatically bypassing a network proxy in the presence of interdependent traffic flows. Messages from a client attempting to establish communication with an origin server are monitored to detect the presence of certain state information. If the origin server is present in one or more bypass lists, the network proxy is bypassed and communication is established between the client and origin sever directly. Otherwise, communication between the client and origin server is established though the network proxy. Messages between at least the origin server and client are monitored in order to identify origin servers for which the network proxy should be bypassed. The bypass lists are automatically updated for such origin servers.
