摘要： A device that implements a method for performing integrated caching in a data communication network. The device is configured to receive a packet from a client over the data communication network, wherein the packet includes a request for an object. At the operating system/kernel level of the device, one or more of decryption processing of the packet, authentication and/or authorization of the client, and decompression of the request occurs prior to and integrated with caching operations. The caching operations include determining if the object resides within a cache, serving the request from the cache in response to a determination that the object is stored within the cache, and sending the request to a server in response to a determination that the object is not stored within the cache.

摘要： The solution of the present invention increases the ability of cache memories to store and serve dynamically generated data. The present invention also enables the cache to effectively deal with a variety of different application request types, thereby increasing application performance and easing the administrative complexity of preserving freshness of data served from the cache. The present invention provides an effective approach to caching dynamic content by the use of heuristics to effectively predict the behavior of such applications servers in addition to incorporating the ability to understand and process data in a way that does not duplicate processing carried out by the application server that originally generates the object. These techniques of the present invention, in turn, increase the use of dynamic caching, and thereby contribute to the improvement of the performance of both the network, as well as underlying application infrastructure.

摘要： A system and method for establishing a virtual private network (VPN) between a client and a private data communication network. An encrypted data communication session, such as a Secure Sockets Layer (SSL) data communication session, is established between a gateway and the client over a public data communication network. The gateway then sends a programming component to the client for automatic installation and execution thereon. The programming component operates to intercept communications from client applications destined for resources on the private data communication network and to send the intercepted communications to the gateway via the encrypted data communication session instead of to the resources on the private data communication network.

摘要： The present invention is directed towards the acceleration of delivery of a computing environment to a remote user of a client at a remote location. The computing environment may include an application and a data file used or processed by the application. The application and data file may be stored or provided via a server remote to the client. The user can request a computing environment from the server that provides for execution of the application by the user via the remote computer. For example, the server may stream the application to the remote client. The client and server may communicate via an appliance that accelerates communications between the client and server. For example, the appliance may accelerate the streaming of the application to the remote user. In some cases, the application or remote user may also request a data file from the server, and the appliance accelerates the delivery of the data file to the remote user. As such, users at remote locations obtain accelerated access via any network connected device to applications and data files located remotely to the user.

摘要： The present invention is directed towards systems and methods for dynamically deploying and executing an acceleration program on a client to improve the performance and delivery of remotely accessed applications. The acceleration program of the present invention is automatically installed and executed on a client in a manner transparent to and seamless with the operation of the client. In one embodiment, the acceleration program is dynamically provided by an appliance device upon determination by the device that the client's access to a server or remote application can be accelerated. In some embodiments, the acceleration program performs one or more of the following acceleration techniques on the client: 1) multiprotocol compression 2) transport control protocol pooling, 3) transport control protocol multiplexing 4) transport control protocol buffering and 5) caching. Also, in some embodiments, the acceleration program performs these acceleration techniques in an integrated and efficient manner at the transport layer using a kernel-level data structure. In another embodiment, the client-side acceleration program performs proxy redirection techniques to automatically bypass any intermediary devices to continuously provided access by the client to the server or a remotely accessed application.

摘要： A method and apparatus for dynamically transcoding and delivering variable bit rate media files delivers media files to client systems. The media server dynamically transcodes a content file to a bit rate requested by a client using an original content file or other transcoded content files. The media server can dynamically select a segment of a content file to transcode. The file format required by the client is determined and the transcoded segment is formatted to the file format. The formatted segment is delivered to the client.

摘要： A method and apparatus for delivering variable bit rate media files delivers media files to client systems. The media server can dynamically detect when a client can accept a different bit rate version of a media content. The media server can smoothly switch between different bit rate versions of the media content as it delivers the media content to client systems. A client system can also request different bit rate versions of a media content while it is playing the media content.

摘要： A method and apparatus stores media content in a variety of storage devices, with at least a portion of the storage devices having different performance characteristics. The system can deliver media to a large number of clients while maintaining a high level of viewing experience for each client by automatically adapting the bit rate of a media being delivered to a client using the client's last mile bit rate variation. The system provides clients with smooth viewing of video without buffering stops. The client does not need a custom video content player to communicate with the system.
