摘要： This invention provides methods and apparatus for web switching without connection termination while providing content routing functionality. Content-aware web switches terminate incoming TCP connections and inspect the HTTP header to recognize the URL (content) being requested from a web server farm. This invention maps application layer information (URLs) to MPLS labels. This allows a standard MPLS switch to provide web switching functionality without terminating TCP connections. In addition to content routing, this method is applied for client session affinity, server load balancing and service differentiation. This invention also relates to using TCP port numbers instead of MPLS labels to achieve web-switching functionality through the use of a TCP router that translates IP address and port numbers.

摘要： This invention provides methods and apparatus for executing applications in a distributed manner employing one or more proxy servers and one origin server. The invention allows the applications to be executed primarily at the proxy servers rather than at the origin servers, thereby gaining in scalability and improved user response time. A redirection mechanism is used to direct requests to one of the proxy servers. The proxy server uses caching techniques to bring information records needed for application execution to the proxy servers. The code required for application execution is also obtained from the origin server. The invention discusses applying this technique to three Web-based applications, namely Web-based auctions, generating personalized content for Web-users, and creating advertisements for users accessing a Web page.

摘要： Methods, systems, and computer program products are provided for performing a secure delete operation in a wide area network (WAN) including a cache site and a home site. A method includes identifying a file for deletion at the cache site, determining whether the file has a copy stored at the home site, detecting a location of the copy at the home site prior to a disconnection event of the cache site from the home site, deleting the file from the cache site during the disconnection event, and performing a secure deletion of the copy at the home site immediately after a reconnection event of the cache site to the home site.

摘要： Embodiments of the invention relate to dynamic application migration in a shared pool of configurable computer resources with disaster recovery support. Data from an application is replicated from local data storage to remote data storage. A consistency point of the data is created in both the local data storage and the remote data storage. The application may be migrated to a second data site with separate local data storage. The migration may be planned or unplanned. Based upon the created consistency point, a consistent set of application data may be requested to support a read operation from the migrated application.

摘要： Scalable caching of remote file data in cluster file systems is provided. One implementation involves maintaining a cache in a local cluster file system and caching local file data in the cache by fetching file data on demand from the remote cluster file system into the local cached file system over the network. The local file data and metadata corresponds to the remote file data and metadata in the remote cluster file system. Updates made to the local file data and metadata are pushed back to the remote cluster file system asynchronously.

摘要： The increasing number of Internet users and innovative new services such as e-commerce are placing new demands on Web servers. It is becoming essential for Web servers to provide performance isolation, have fast recovery times, and provide continuous service during overload at least to preferred customers. The invention describes a kernel-based architecture for content-aware service differentiation that protects Web servers against overload by controlling the amount and rate of work entering the system. We have invented a mechanism that provides admission control and service differentiation based on connection and application level information. The application header-based connection control uses application-level information (such as URIs and cookies for HTTP) to define different service differentiation actions. The present invention provides the kernel mechanisms that are more efficient and scalable than application level controls implemented in current Web servers.
摘要翻译：越来越多的互联网用户和创新的新服务，如电子商务正在为Web服务器提出新的要求。 Web服务器至关重要的是提供性能隔离，快速恢复时间，并在至少向优先客户过载时提供持续服务。本发明描述了用于内容感知服务差异化的基于内核的架构，其通过控制进入系统的工作量和速率来保护Web服务器免受过载。我们发明了一种基于连接和应用级信息提供入网控制和服务差异化的机制。基于应用程序标头的连接控制使用应用程序级信息（例如HTTP的URI和Cookie）来定义不同的服务区分操作。本发明提供了比当前Web服务器中实现的应用程序级别控制更有效和可扩展的内核机制。
