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 Encrypted Transport Proxy Backbone Protocol module is configured to set up ET Proxy Backbone connections with another distributed proxy device with each ET Proxy Backbone connection including multiple ET Proxy Backbone channels for transmitting ET proxy packets having different QoS classes. Each ET Proxy Backbone channel includes a separate queue. The ET Proxy Backbone Protocol module is also configured to schedule transmissions of the ET proxy packets from each respective queue; multiplex the ET proxy packets from each respective queue via the associated ET Proxy Backbone channel; perform local recovery of network impairments over the access network and perform congestion control to prevent packets from client devices and web servers from causing network congestion to the access network.

摘要： A method of switching from a first gateway within a plurality of first gateways to a second gateway in a network includes precaching configuration information on the second gateway, that is within the first gateways, prior to switch-over to the second gateway. The first gateway from which the second gateway is being switched is identified. The second gateway is configured in accordance with the configuration of the first gateway based on the precached configuration information prior to the switch-over to the second gateway. Data traffic from data applications using the network is replicated and sent to the first gateway and the second gateway. Bandwidths allocated to terminals in the network are frozen in association with the switch-over to the second gateway. The bandwidths allocated to the terminals in the network are unfrozen based at least in part on an indication of completion of the switch-over to the second gateway.

摘要： A data buffering control system and method for a communication network comprises a buffer disposed at a destination site, and a controller. The buffer is configured to buffer data received at a data receiving rate by the destination site for delivery by the destination site to a user at a delivery flow rate. The controller is configured to increase or decrease a buffering rate according to which the data is buffered in the buffer based on an amount of buffered data in the buffer without stopping the buffering of the data in the buffer. The controller is configured to perform a transmission control protocol spoofing process at the destination site to effect a communication handshaking operation, without the destination site communicating with a source providing the data, to control the data receiving rate by the destination site, to thus modify the buffering rate.

摘要： An Encrypted Transport (ET) proxy module is configured to receive incoming ET proxy packets from an ET proxy backbone module and transmit outgoing ET proxy packets to the ET proxy backbone module. The ET proxy module is also configured to set up an HTTP tunnel with an ET proxy client of the client device or with an ET proxy at a web server for receiving incoming UDP payloads from the client device or web server and transmitting outgoing UDP payloads to the client device or web server. The ET proxy module is also configured to receive prioritization preferences from client devices or web servers pertaining to the UDP payloads indicating preferred quality-of-service (QoS) classes for the UDP payloads, and to schedule transmission of the outgoing UDP payloads via the HTTP tunnel based on QoS classes of the outgoing UPD payloads.

摘要： Dynamic in-route reconfiguration in a satellite network includes receiving at least one of transmit power capability and demand requirements from one or more active satellite terminals of the satellite network, determining a resulting in-route configuration during operation of the satellite network based on the received at least one of transmit power capability and demand requirements, comparing the determined resulting in-route configuration to a current in-route configuration. When the determined resulting in-route configuration is different from the current in-route configuration, establishing the determined resulting in-route configuration as the current in-route configuration and storing the established current in-route configuration in a dynamic in-route reconfiguration manager, and transmitting the established current in-route configuration to the one or more active satellite terminals.

摘要： A method of and system for designing a satellite network includes selecting an optimal design for a backhaul network to be used as part of the satellite network, selecting a number of radio frequency (RF) gateways for the satellite network, selecting an optimal number of satellite network cores (SNCs) for the satellite network. The method may also include placing each SNC at a site that is geographically separate from locations of the RF gateways, selecting a number of data centers for the satellite network, connecting each SNC to one or more data centers in the satellite network, and connecting each data center to one or more of the RF gateways via the backhaul network.
