Abstract: Methods and systems consistent with the present invention provide efficient packet replication in a router in order to multicast a stream of data. Packets are replicated and processed in a multithreaded environment. Embodiments consistent with the present invention implement a two-stage process for packet replication. The first stage thread will recirculate the packet to multiple second-stage threads. These second-stage threads will then create one or more outgoing copies of the packet. In this way, the copies are handled by multiple threads running in parallel.

Abstract: A system, method and computer program product for scalable metadata acceleration with datapath metadata backup as disclosed includes providing a plurality of metadata comprising variable block pointers for the physical location of system data. The method also includes storing at least a first and a second metadata in two or more solid state memories accelerated with respect to a read and a write of a memory in a datapath, each solid state memory configured as a logical copy of the other. The method additionally includes interleaving a backup metadata in a datapath memory at a variable interval based on a table of block pointers. The method further includes querying the accelerated metadata for an accelerated datapath operation of the system and querying the interleaved metadata and/or a logical mirror of the accelerated metadata for a rebuild operation of the accelerated metadata, each query determinable by the table of block pointers.

Abstract: A method for creating multiple tagged clinical trial data and a tool therefrom is disclosed. The method comprises receiving clinical trial information from different sources, and removing redundancies from the clinical trial information received from the plurality of sources to form collated clinical trial data. The method further involves baseline tagging of the collated clinical data using non-indication parameters, creating a disease specific list of indication parameters, where indication parameters are classified into at least main indication parameters and sub indication parameters. The method further includes advanced tagging of the collated clinical trial data using indication parameters and creating multiple tagged clinical data using baseline tagging and advanced tagging.

Abstract: In one aspect, the invention provides a clinical trial information management tool. The tool comprises an interface with a multiple tagged clinical trial database; a user interface for receiving user inputs, a search engine to query the multiple tagged clinical trial database in one or more levels based on user inputs; a display platform to display results from the query in one or more views; an analytics engine to provide at least one of parameter based analysis and graphical analysis; and a personalization platform to store the query and the results. The tool provides the advantage through the rapid, facile and user-friendly manner in which clinical trial information from a wide variety of sources may be searched, analyzed and reported by a user, which allows for easy strategizing regarding clinical trial related matters, among other unique advantages.

Abstract: A method for emulating a nexthop instruction in microcode with the assistance of dedicated hardware to extract read and write addressing from the nexthop instruction instead of performing this operation in microcode. A method for emulating a nexthop instruction in microcode with the assistance of dedicated hardware to compare a nexthop read address to a special value and to indicate whether the nexthop read address matches the special value, instead of performing this operation in microcode. A method for determining a network address by performing a single extraction of bit fields of a tree instruction to allow multiple tree search processes to be performed.

Abstract: Methods and devices for qualifying a client machine to access a network, based on policies governing required protective measures, such as virus checking and operating system updates, are disclosed. A client machine must pass various checks to qualify for access. A client machine may be redirected to remediation resources that support efforts to bring the client machine into compliance with applicable network access requirements. A policy repository is updated regularly by vendors of protective measures. An administrator establishes user roles that are mapped to policy rule sets retrieved from the policy repository. The policy rule sets govern qualification of client machines for access to the network in accordance with the roles of the users of the machines. An access server is an intermediary between a client machine and the access manager. A client agent runs on the client machine and carries out checks, and reports the results via the access server to the access manager.

Abstract: The present invention relates to methods and devices that support mobility of a client across a campus, particularly mobility across VLANs and subnets, while preserving the client's assigned IP address. Both layer 2 and layer 3 packets are supported. Mobility support most clearly applies to wireless clients, but could apply to other kinds of mobile connections, even to wired connections. A smart server is adapted to support multiple VLANs and to modify and redirect packets in sessions with a client that moves from one VLAN to another, preserving the client's assigned EP address. Two or more smart servers, in cooperation with a smart manger, modify packets and tunnel them between smart servers when a client that moves from one VLAN to another and from one smart server to another, again preserving the client's assigned IF address.
