摘要： An approach is provided for supporting retrieval of a web page over a data network from a web site is disclosed. A downstream proxy communicating with a host executing a browser receives a request message from a browser to retrieve the web page. An upstream proxy parses the web page to determine an object embedded in the web page, wherein a promise list is generated specifying the embedded object that is to be pre-fetched according to a criterion. The promise list is transmitted to the downstream proxy, wherein the upstream proxy pre-fetches the embedded object from the web site. The upstream proxy determines whether to forward one of the pre-fetched embedded object to the downstream proxy based on a comparison of cookies associated with one of the pre-fetched objects supplied, respectively, by the browser and the web site. This approach as particular applicability in relatively high latency networks, such as a satellite communications system.

摘要： An approach for providing secure access to inroutes or return channels in a radio communication system including a hub communicating with terminals is disclosed. A quality of service level (QoS) corresponding to one of the terminals is determined. An identifier is assigned to the one terminal for communicating over a set of return channels that are in the direction of the one terminal to the hub. The identifier associates a subset of the terminals with the QoS level; the subset includes the one terminal. This arrangement has particular applicability to a satellite network that provides data communication services.

摘要： A system for managing return channel bandwidth in a two-way satellite communication network is disclosed. A plurality of transceivers are configured to transmit backlog information over a return channel via a satellite. The backlog information specifies an amount of queued traffic for the respective transceivers. A hub is configured to receive the backlog information and to allocate a predetermined amount of return channel bandwidth to each of the plurality of transceivers. The hub determines whether additional return channel bandwidth is available to accommodate a remaining backlog such that a bandwidth allocation amount is set to a level associated with one of the plurality of transceivers having the largest backlog. The hub selectively identifies a transceiver among the plurality of transceivers having a next largest backlog based upon the determined available return channel bandwidth. The hub selectively adjusts the bandwidth allocation amount to a level associated with the transceiver with the next largest backlog. The hub allocates the additional return channel bandwidth to the plurality of transceivers based upon the adjusted bandwidth allocation amount if the adjusted bandwidth allocation amount reduces at least a portion of the backlog of the plurality of transceivers.
