Abstract: A method and system is provided for implementing service chain measurement and monitoring in a client management tool. A central monitor establishes a performance threshold for two or more components forming a service chain. One or more management templates, corresponding to the performance threshold, are issued to the components for monitoring. If the performance fails to meet the performance threshold, an indication of the failure is provided to a computer system operator.

Abstract: A web site is provisioned with a proxy that receives a page request intended for the server and records a first time. The page request is then forwarded to the server for response. The response stream generated by the server is intercepted at the proxy at a second time. As the stream is forwarded to the requesting client, the proxy inserts a page script that, upon execution at the client, calculates a page render time. This time is determined by calculating the difference between a third time (the time at which the page script begins execution at the client) and a fourth time (a time at which the page rendering is complete). Upon completion of the page rendering, the script opens a connection back to the server and returns a packet that includes the page render time. This packet is received at a fifth time. A transaction record is then built by the proxy using the timestamp data.

Abstract: A Web address converter helps dynamic Web sites get the attention of spiders of Internet search engines. With the Web address converter, requests from Web browsers using static addresses access corresponding dynamic Web pages and requests from search engines generate an instance of a Web page having links with static addresses pointing to corresponding dynamic Web pages. The Web address converter performs both Dynamic-to-Static (D-to-S) address conversion and Static-to-Dynamic (S-to-D) address conversion. D-to-S address conversion is done when generating a spider-friendly main page for a spider of a search engine to crawl. S-to-D address conversion is used when a browser uses a static address to access a corresponding dynamic Web page. The static address that the browser uses was originally created when the spider-friendly main page was generated.

Abstract: A switched file system, also termed a file switch, is logically positioned between client computers and file servers in a computer network. The file switch distributes user files among multiple file servers using aggregated file, transaction and directory mechanisms. The file switch distributes and aggregates the client data files in accordance with a predetermined set of aggregation rules. Each rule can be modified independently of the other rules. Different aggregation rules can be used for different types of files, thereby adapting the characteristics of the switched file system to the intended use and to the expected or historical access patterns for different data files.

Abstract: Methods for reconfiguring binary tree topology networks upon the departure of a departing node are described. A register message is sent from a child node to a parent node, the register message requesting that the parent node dock uptree of the child node. In response, a register accept is sent from the parent node to the child node, thus docking the parent node uptree of the child node. A priority join message is sent from a second child node to the first child node requesting that the first child node dock uptree of the second child node. A disconnect propagate message is sent from the first child node to a grandchild node upon receiving a priority join message from the second child node. A join accept is sent from the first child node to the second child node, thus docking the first child node uptree of the second child node.

Abstract: A method of servicing a request for a document over a computer network includes independently caching portions of pages called blocks. Each block includes a reference to a data source and code that is adapted to access the data source and to format the data accessed from the data source. When a request for a page is received over a computer network, one or more of the plurality of blocks defined in the script of the requested document may be retrieved from a cache memory. Any block that is not found in the cache memory is dynamically generated and a copy thereof is stored in the cache memory. The requested page may then be assembled from the page blocks retrieved from the cache memory and/or the dynamically generated page blocks.

Abstract: A system and method for filtering of web-based content in a proxy cache server environment provides a local network having a client, a directory server and a proxy cache server that caches predetermined Internet-derived web content within the network. When content is requested, it is vended to the client only if it meets predefined user policies for acceptability. These policies are implemented based upon one or more ratings lists provided by content rating vendors. The lists are downloaded to the network in whole or part, and cached for use in determining acceptability of content by a filter application. Ratings can be particularly based upon predetermined content categories. Caching occurs in a host or object cache for rapid access. Only if current ratings are not found in the host or object caches are ratings caches or vendors accessed for ratings. Ratings on requested content are then placed in the host or object cache for subsequent use.
