A system and method for interfacing TCP Offload Engines (TOE) into an operating system to improve system performance and reduce CPU utilization. The system and method places an interposed filter before the generic user space socket library near the top of the TCP stack to intercept at the earliest possible layer a user application network socket request. The interposed filter determines whether an I/O request is targeted for a generic network adapter or a full TOE network adapter. For I/O requests that are targeted to a full TOE network adapter, the request is formatted to meet the requirements of the full TOE driver and sent directly to that driver, bypassing the operating system's generic user space socket library and socket driver in kernel space. This system and method takes full advantage of the capabilities offered by TOE hardware.

A technique is disclosed that allows different computers in a network to create an identifier that uniquely identifies the network. The technique allows the unique identifier to be consistently created over time, regardless of the particular make up of the computing devices in the network at any particular point time. In some implementation, a computer within the network hosts the identification creation tool. In order to create a unique identifier for the network, the tool identifies each network adapter used by the host computer. Using this information, the tool identifies a gateway device used by the network adapter or adapters, and then determines the physical network address of that gateway device. For example, if the network is an Ethernet network, the tool will determine the medial access control (MAC) address for the gateway device. The tool then creates a unique identifier for the network based upon the physical address. The unique network identifier can then be used to associate the billing a usage fee, such as a licensing fee, with the network rather than with an individual computer within the network. Alternately or additionally, the unique network identifier can be used to maintain and support the gateway device for the network.

A cloud computing system is described herein that enables fast processing of queries over massive amounts of stored data. The system is characterized by the ability to scan tens of billions of data items and to perform aggregate calculations like counts, sums, and averages in real-time (less than three seconds). Ad hoc queries are supported including grouping, sorting, and filtering without the need to predefine queries by providing highly efficient loading and processing of data items across an arbitrarily large number of processors. The system does not require any fixed schema, thus the system supports any type of data. Calculations made to satisfy a query may be distributed across a large number of processors to parallelize the work. In addition, an optimal blob size for storing multiple serialized data items is determined, and existing blobs that are too large or too small are proactively redistributed or coalesced to increase performance.

A method of processing a document object model (DOM) tree having at least one tag located at a given node in the tree. The tag serves as a marker that initiates the invocation of a tag handler that, in turn, performs a simple macro substitution or a more complex algorithmic reorganization and manipulation of the tree. Upon encountering the tag, given information is passed to a method. In a first embodiment, the given information is a text representation of XML in the DOM tree at the given node and any child nodes of the given node. In an alternate embodiment, the given information is the given node of the DOM tree itself. The method generates an XML string, which is then parsed into a new DOM tree having a root node. The given node and any child nodes are then replaced by the new DOM tree, with the root node of the new DOM tree being positioned at the given node in the original DOM tree. The process may then be repeated for any additional tags.

A method and apparatus is described for controlling accesses to a shared resource. An arbitration mechanism uses a register, accessible by each device sharing the resource. The register may be written by the device to request access to the resource, and read by the device to determine whether access to the resource has been granted. Advantageously, the register includes an override bit, which may be used by either device to override the peer device's request for the shared resource. In addition, the register includes a reset bit that may be used to reset arbitration logic controlling the access to the shared logic. The register is used by a straightforward arbitration mechanism that includes only IDLE and GRANT states for each device coupled to the shared resource. Such an arrangement provides a low cost method of controlling accesses to a shared resource.

Mechanism for two portions of an application to communicate so as to facilitate a transition from synchronous to asynchronous communication. In order to prepare for a possible transition, data flow is monitored between the two portions of the application, each portion interacting with a different hardware entity. The data flow between the first portion and the second portion of the application is recorded. If the second hardware entity is not available at the time, the recorded data flow from the first portion may be replayed by the second portion of the application for the benefit of the second hardware entity. If the second portion of the application is to be reassigned to another hardware entity, the target hardware entity may be sent the second portion of the application, as well as the recorded information. This allows the target hardware entity to replay what has happened thus far for context.

A method for a network infrastructure copy protection system. The method includes the step of applying a digital signature to a digital content file prior to transmission. Digital content files that are to be legitimately transmitted across the distributed computer network are modified by the application of digital signatures corresponding to the sender. As content files are transmitted across a distributed computer network, the distributed computer network examines the content files to determine whether they include the digital signatures. The examining is performed by hardware comprising the infrastructure of the distributed computer network. When content files include respective digital signatures, the content files are transmitted by the infrastructure. When the content files do not include the digital signatures, transmission of those content files not having digital signatures is blocked. The digital signatures are configured to identify the senders of the digital content files. The digital signatures can be logged within the distributed computer network to maintain a record of the digital content files as they are transmitted. The hardware performing the examining can be a plurality of routers or a plurality of cache engines within the distributed computer network.
