Abstract: A computer system includes an interface and a processor. The interface is adapted to receive a request from another computer system for identification of the first computer system. The adapter also furnishes a hash value that identifies the first computer system to the other computer system. The processor is coupled to the interface and is adapted to encrypt an identifier that identifies the first computer system with a key associated with the other computer system to provide the hash value.

Abstract: A method and system for searching for information is disclosed. The method includes storing a plurality of content categories and identifying, according to properties returned by a plurality of search engines, at least one search engine suited to service a query where the query has at least one content category of the plurality of content categories. The system includes a processor and a machine-readable medium including instructions that when executed by the processor result in performance of the disclosed method.

Abstract: A method includes querying a plurality of search engines for properties to identify for which content categories the search engines are suited. A query to locate content is communicated to those of the plurality of search engines suited to service the query to locate content, based on at least one content category of the query to locate content.

Abstract: Distributed usage metering of network packet traffic, requiring fewer metering devices than ultra-fine-grain metering, more scalable than centralized metering, and providing weighted packet history analysis on various packet characteristics, with redefineable weight definitions.

Abstract: A method includes storing a plurality of content categories and identifying, according to properties returned by a plurality of search engines, at least one search engine suited to service a query having at least one content category.

Abstract: A method includes querying a plurality of search engines for properties to identify for which content categories the search engines are suited. A query to locate content is communicated to those of the plurality of search engines suited to service the query to locate content, based on at least one content category of the query to locate content.

Abstract: A customer premises gateway including a traffic analyzer with usage tracking to detect fraud such as in the case of masquerading by a router attached to the gateway, and a head-end server including fraud detection and a billing system for providing a maximum bandwidth specifier to the gateway. In the case of Internet Protocol, the traffic and fraud analysis may utilize the address:port combination and also the traffic type specifier to detect fraud and masquerading and to control bandwidth.

Abstract: A method and arrangement for scheduling the transmission of data files among a plurality of interconnected computers is disclosed. When a first computer desires to transmit data files to a second computer, the first sends a short duration message to the second defining a future time when transmission will occur. If this future time is available on the second computer, a short duration acknowledgment message is returned to the first. If the future time is not available on the second computer, no acknowledgment message is returned. The first computer transmits the data files to the second at the future time, if an acknowledgment message has been received. Such data file transmission does not occur if no acknowledgment message has been received. However, the first computer may send a new request specifying a different future time. Alternatively, a request message may contain a plurality of future times for data file transmission.
