Abstract: The fast dynamic measurement of connection bandwidth utilizes a single pair of packets to calculate bandwidth between two entities on a network (such as the Internet). This calculation is based upon the packet-pair technique. This bandwidth measurement is extremely quick. On its journey across a network, communication equipment and modems may compress a packet. This compression shrinks the size of the packet; thus, it can distort the bandwidth calculation using such a shrunken packet. To avoid this distortion, the fast dynamic measurement of connection bandwidth employs non-compressible packets. More specifically, it employs highly entropic packets. Therefore, a packet cannot be compressed during its journey. In addition, on its journey across a network, packets may be rerouted, delayed, misrouted, and the like. These momentary delays may result in a momentary bad bandwidth calculation. This problem is ameliorated by using a history list at the client that keeps track of recent measurements.

Abstract: Information services may be provided to a user of a personal digital assistant (PDA) via an infra red wireless communication port. The PDA recruits communication with a peer, such as a beacon, via this link, and the PDA and peer exchange messages containing the URLs of their proxies within the Internet. The proxies contact each other and negotiate, via the exchange of XML documents, parameters governing exchange of messages via the infra red link, such parameters being related inter alia to technical aspects of communication (e.g. file size, software compatibility etc.), encryption (e.g. public key information), and policy, which determines what the IR wireless link may be employed for, such as what content is sought. Negotiation between proxies is relatively rapid due to the higher bandwidth of the link between them in comparison to the IR link.

Abstract: Methods, systems, and computer program products are disclosed for sharing data related to a session created by a user within a domain of sites or services. A user logs on to a site, such as a Web site or other entity, and creates a session. The session created has an identifier which can be shared with other sites or entities in the same domain or logical group. In the course of utilizing services on the site, the user attempts access to services on another site. When this attempt is made, the user's session data is passed to the second site. The session data is analyzed on the second site by checking configuration data on the second site. If it is not found to be valid (e.g. it is created by a site outside the domain of the second site), the user is required to explicilty logon. If the configuration data indicates that it is valid, the session data is passed back to the first site using a verification routine (part of the configuration data) on the second site.

Abstract: The present invention is a system and method to improve the reliability and performance of existing enterprise IP networks which have dual-homed (or multi-homed) network architectures. In one aspect of the invention packets related to a selected category of transmission (e.g., VoIP) are duplicated at an edge router and sent over both (multiple) service providers. After traversing the service provider networks, only the first-to-arrive packets are kept and the later-arriving copies are discarded. In so doing, the result is better protection against node failures, link failures, and packet errors, and also better QoS performance under normal (fault-free) operation.

Abstract: A technique for increased efficiency of content delivery over a network is described. Instances of web pages are divided into (1) templates including those elements of a web page that are relatively unchanging and (2) delta information including those elements that are ephemeral or customized. Each template is compressed and cached at an originating server. Transmission of the delta information is decoupled from transmission of the template. When a user requests a page, the compressed template is sent (either from an originating server or a mirror thereof). The delta information is compressed and sent separately. Since the template is only compressed once and is cached locally, it requires less bandwidth and allocation of other computing resources to transmit than transmission of a compressed web page.

The translation logic translates an allocate and rename instruction into a micro instruction sequence that directs a microprocessor to allocate a first cache line in an exclusive state and to copy the contents of a second cache line into the first cache line. The execution logic is coupled to the translation logic. The execution logic receives the micro instruction sequence, and issues transactions over a memory bus that requests the first cache line in the exclusive state. Upon granting of exclusive rights, the execution logic copies the contents of the second cache line into the first cache line.

Abstract: Systems and methods which provide an extensible caching framework are disclosed. These systems and methods may provide a caching framework which can evaluate individual parameters of a request for a particular piece of content. Modules capable of evaluating individual parameters of an incoming request may be added and removed from this framework. When a request for content is received parameters of the request can be evaluated by the framework and a cache searched for responsive content based upon this evaluation. If responsive content is not found in the cache, responsive content can be generated and stored in the cache along with associated metadata and a signature formed by the caching framework. This signature may aid in locating this content when a request for similar content is next received.
