A runtime adaptable search processor is disclosed. The search processor provides high speed content search capability to meet the performance need of network line rates growing to 1 Gbps, 10 Gbps and higher. The search processor provides a unique combination of NFA and DFA based search engines that can process incoming data in parallel to perform the search against the specific rules programmed in the search engines. The processor architecture also provides capabilities to transport and process Internet Protocol (IP) packets from Layer 2 through transport protocol layer and may also provide packet inspection through Layer 7. Further, a runtime adaptable processor is coupled to the protocol processing hardware and may be dynamically adapted to perform hardware tasks as per the needs of the network traffic being sent or received and / or the policies programmed or services or applications being supported. A set of engines may perform pass-through packet classification, policy processing and / or security processing enabling packet streaming through the architecture at nearly the full line rate. A high performance content search and rules processing security processor is disclosed which may be used for application layer and network layer security. Scheduler schedules packets to packet processors for processing. An internal memory or local session database cache stores a session information database for a certain number of active sessions. The session information that is not in the internal memory is stored and retrieved to / from an additional memory. An application running on an initiator or target can in certain instantiations register a region of memory, which is made available to its peer(s) for access directly without substantial host intervention through RDMA data transfer. A security system is also disclosed that enables a new way of implementing security capabilities inside enterprise networks in a distributed manner using a protocol processing hardware with appropriate security features.

An Internet-based electronic commerce (EC) enabled shopping system comprising: an Internet information server connected to the infrastructure of the Internet and supporting the hypertext transmission protocol (http); a Web-enabled client subsystem connected to the infrastructure of the Internet; and an EC-enabled WWW site comprising a plurality of interlinked HTML-encoded documents arranged and rendered to provide an electronic store environment for a consumer when served to the Web-enabled client subsystem, wherein the electronic store environment presenting a plurality of products for purchase and sale by an EC-enabled payment method supported over the Internet, wherein a Consumer Product Information Request (CPIR) enabling Server-side component tag, associated with each the product, is embedded within at least one of the HTML-encoded documents displayed on the Web-enabled client subsystem, and each the CPIR-enabling Server-side component tag being associated with a CPIR-enabling Server-side component encoded with a Universal Product Number (UPN) assigned to one the product, and whereby, when the consumer selects one the CPIR-enabling Server-side component tag, the associated CPIR-enabling Server-side component is automatically executed, enabling a search to be conducted against a product information database hosted on an Internet database server connected to the Internet, and the results from the search displayed in a graphical user interface (GUI) served to and displayed on the Web-enabled client subsystem.

Techniques for reducing peak-to-average power in multicarrier transmitters employ peak cancellation with subcarriers that are impaired by existing channel conditions. The use of Carrier Interferometry (CI) coding further improves the effectiveness of peak reduction. CI coding can also be impressed onto pulse sequences in the time domain, which enhances spectral selection and facilitates peak-power control.

The invention provides a method, system and computer-readable medium for storing images with related information in a relational database and using the information to order available products for a selected image over a network. Tag and business information may be associated with an image in the database and a unique image identifier is generated for each image. Different types of searches of the relational database may be performed including product based and image based. Affirmative results from searches are returned as images and / or products that are displayed in pages. The returned images also include information indicating available products. The selection of a returned image causes a cut-down version of the image and all of the available products to be displayed in the same page. When an available product is selected, a server enables a transaction for a user to order the selected product. A Hyper Text Transport Protocol (HTTP) Cookie is employed to store a copy of a client identifier at a client. Information associated with the client's behavior for each session is stored in a profile that is used to customize the particular options and products that are displayed to the user. A combination of user information, product information, image information and contextual interaction information is used to determine the display of the images and the products.

Message publish / subscribe systems are required to process high message volumes with reduced latency and performance bottlenecks. The end-to-end middleware architecture proposed by the present invention is designed for high-volume, low-latency messaging by, among other things, reducing intermediary hops with neighbor-based routing, introducing efficient native-to-external and external-to-native protocol conversions, monitoring system performance, including latency, in real time, employing topic-based and channel-based message communications, and dynamically optimizing system interconnect configurations and message transmission protocols.

The present invention provides a method and an apparatus for communicating data over a network between a communication node, for example, an access point having a first and a second antenna and a first and a second mobile station. The method comprises weighting a first data at the access point to transmit the first data using the first and second antennas so that the first mobile station only receives the first data and weighting a second data at the access point to transmit the second data using the first and second antennas so that the second mobile station only receives the second data. A space division multiple access (SDMA) module may cause a transmission protocol to transmit the first data to the first mobile station on the downlink and transmit the second data to the second mobile station in parallel to the transmission of the first data on the downlink. In a telecommunication system, this substantially simultaneous transmission of the first and second data using a similar carrier frequency in a radio frequency communication over a wireless local area network (WLAN) may increase throughput of a downlink, for example, by a factor nominally equal to the number of antennas at an access point.
