Systems and methods for prefetching objects for caching using QOS
ActiveUS7584294B2Improve efficiencyImprove intermediary or proxy cachingMultiple digital computer combinationsData switching networksClient agentTraffic capacity
The present solution provides a variety of techniques for accelerating and optimizing network traffic, such as HTTP based network traffic. The solution described herein provides techniques in the areas of proxy caching, protocol acceleration, domain name resolution acceleration as well as compression improvements. In some cases, the present solution provides various prefetching and / or prefreshening techniques to improve intermediary or proxy caching, such as HTTP proxy caching. In other cases, the present solution provides techniques for accelerating a protocol by improving the efficiency of obtaining and servicing data from an originating server to server to clients. In another cases, the present solution accelerates domain name resolution more quickly. As every HTTP access starts with a URL that includes a hostname that must be resolved via domain name resolution into an IP address, the present solution helps accelerate HTTP access. In some cases, the present solution improves compression techniques by prefetching non-cacheable and cacheable content to use for compressing network traffic, such as HTTP. The acceleration and optimization techniques described herein may be deployed on the client as a client agent or as part of a browser, as well as on any type and form of intermediary device, such as an appliance, proxying device or any type of interception caching and / or proxying device.

Jitter buffer management
ActiveUS20050207437A1Extension of timeAvoids large discontinuityTime-division multiplexData switching by path configurationArrival timeSnubber
A sample jitter buffer manager more or less aggressively conserves (rations) or discards data in a jitter buffer, based on the fluctuating amount of data in the jitter buffer. The jitter buffer manager counts, provides, discards and / or otherwise manages individual sample data units, rather than entire packets. Normally, enough data is removed from the jitter buffer to fill a data packet for a receiver. However, if the amount of data in the jitter buffer is low, less data is removed from the jitter buffer and placed into the packet, and the remainder of the packet is filled with duplicates of some of the data in the packet or in the jitter buffer. As the jitter buffer fills beyond a useful level, the jitter buffer discards progressively larger amounts of data, without necessarily discarding one or more entire packets. This fine-grained management of the amount of data in the jitter buffer maintains a buffer size that can provide a steady stream of packets to the receiver, without significantly impacting the fidelity of a signal represented by the data, and it mitigates the impact of fluctuations in packet inter-arrival times.

A virtual size information is attached to encoded picture data when generating the encoded picture data for example by a transcoder. The virtual size information is used for resizing a picture or a video having a sequence of pictures to increase the subjective quality of the displayed information. The virtual size information is generated on the encoder-side and transmitted to the decoder-side and used by the resizer to resize the transmitted information to a degree, which results in an optimum subjective quality determined by a trade-off between interpolation artefacts and picture size.
