Abstract: According to one embodiment of the present invention, a method is provided for measuring performance of service provided to a client by a server in a client-server network. The method comprises capturing network-level information for a client access of data from a server in a client-server network, wherein the client-server network comprises a server side and a client side and wherein the network-level information is captured on the server side. The method further comprises determining from the captured network-level information at least one performance measurement relating to the client access of data.

Abstract: According to one embodiment of the present invention, a method for compiling desired information for network transactions is provided. The method comprises capturing network-level information in a kernel-level module of a processor-based device arranged on the server-side of a client-server communication network, and using the captured network-level information to compile, in the kernel-level module, desired information for at least one network transaction conducted between a client and a server via the client-server communication network. Another embodiment of the present invention provides a method for compiling desired information for network transactions that comprises implementing a kernel-level module in a STREAMS-based network stack of a server, wherein the kernel-level module is operable to monitor a network connection to the server to compile desired information for network transactions conducted through the network connection.

Abstract: According to one embodiment of the present invention, a method for reconstructing client web page accesses is provided that comprises capturing network-level information for client accesses of at least one web page. The method further comprises constructing a knowledge base of reliable information identifying content of at least one web page, and reconstructing at least one client web page access from the captured network-level information using the reliable information of the knowledge base.

Abstract: According to one embodiment of the present invention, a method for reconstructing client web page accesses is provided that comprises capturing network-level information for client accesses of at least one web page, and using the captured network-level information to reconstruct client accesses of the at least one web page. Another embodiment of the present invention provides a method for reconstructing client information accesses. The method comprises capturing network-level information for client accesses of information from a server, wherein each client access of the information comprises a plurality of transactions. The method further comprises relating the plurality of transactions to their corresponding client access of information from the server.

Abstract: A method and system for handing-off TCP states in a communication network. Specifically, the present invention allows for handing-off TCP states between nodes in an associated network that is optimized for rare handoff of TCP states. The handoff occurs between dynamically loadable modules that wrap around the TCP/IP stack located at a front-end node and a selected back-end web server. A handoff protocol implemented by the loadable modules works within the kernel level of the existing TCP/IP code. As such, no changes to the existing TCP/IP code is necessary. The loadable modules at the front-end are able to select a back-end web server depending on the content of the web request, coordinate handing off TCP states, and forward packets to the back-end web server. Loadable modules at the selected back-end modify response packets going out to reflect the proper TCP state of the front-end node.
