Abstract: A distributed, redundant, multi-homed system collects and aggregates website usage information. Two or more data collection nodes, preferably situated in diverse locations, efficiently collect and time-stamp information from users in a wide variety of geographic locations. Data collected by the individual data collection nodes is aggregated at a master processing center, sorted according to time stamps, and subjected to statistical analysis in order to generate complete and accurate reports regarding website traffic.

Abstract: A system and method permits a network management agent executing on a customer premise equipment (CPE) component to determine whether a router is coupled between the CPE component and the cable modem through which the CPE component communicates with a data-over-cable network. The network management agent executing on the CPE component encapsulates the MAC address of the CPE component in a network management message that is sent to a server at the head end of the data-over-cable network. The head end compares the encapsulated MAC address with the MAC address of the device coupled to the cable modem that sent the network management message. If the MAC addresses are not the same, the server at the head end sets a router status element in the network management message response and sends it to the agent executing on the CPE component.

Abstract: In general, this disclosure describes techniques of managing resources in a service-oriented distributed computing system. As described in this disclosure, a control node automatically manages the system such that the system has sufficient capacity to satisfy an agreement to provide a given level of a service. In order to automatically manage the system, the control node evaluates the current capacity levels of resources in the system. The current capacity levels are indicative the capacity of resources to perform certain acts. The capacity of the resources to perform these acts may be indicative of whether the system is able to provide the given level of the service. Because capacities provided by the resources change as the resources start, the control node uses a predicted pending capacity function to evaluate whether resources that are currently starting will be sufficient to satisfy the level of the service when completely started.

The discovery of components can be carried out using fingerprints of components, which can include key elements of the component that exist in a full model of all of the elements of the component.

Abstract: A new method and framework for re-partitioning directory servers supporting user services in a site that receives access requests from users. According to the present invention, a management server transfers groups of directory objects from original directory servers to newly added directory servers without service interruption to users of the site. The directory objects are stored in categorical groups such that the directory objects in each group share an attribute. According to the present invention, certain groups in the original directory servers are identified for migration to the newly added servers based on a load-balancing scheme. In one embodiment, the identified groups are marked for migration to limit access to the directory objects therein. After successfully being migration, the groups are unmarked and access is resumed.

Abstract: An industrial control system provides a programmable logic controller communicating with I/O modules which provide an electrical interface to controlled equipment and which support web servers for communication of I/O data directly with the Internet. The programmable logic controller communicates with the I/O modules over a control-network which may be separate from or shared with the Internet communications. A lock-out system prevents collisions between web clients writing to I/O and allows the programmable logic controller to limit web access to critical I/O points.

Abstract: A web page, including clickthroughs, is cached at a location within a network intermediate a client requesting the page and the host web site for the page. Clickthrough activation (in session cache on the client machine, or in the network cache) causes a javascript program to generate an activation identifier giving the IP address of the machine activating the clickthrough and the time. This ID and an ID for the IP address from which the web page originally hosting the clickthrough was retrieved are sent to the host web site. Generating such identifiers is applicable to text messages, e.g. sent out by a publicity agent, and actuable to connect to a telephone number held by an enterprise within the telephone network. Activating such a text message causes the return of suitable identifiers to the publicity agent to enable them to seek renumeration from the enterprise.

Abstract: An instrument-based distributed computing system is disclosed that accelerates the measurement, analysis, verification and validation of data in a distributed computing environment. A large computing work can be performed in a distributed fashion using the instrument-based distributed system. The instrument-based distributed system may include a client that creates a job. The job may include one or more tasks. The client may distribute a portion of the job to one or more remote workers on a network. The client may reside in an instrument. One or more workers may also reside in instruments. The workers execute the received portion of the job and may return execution results to the client. As such, the present invention allows the use of instrument-based distributed system on a network to conduct the job and facilitate decreasing the time for executing the job.

Abstract: A method includes producing units of work with at least one source application instance (AI) at a source device and consuming units of work with at least one destination AI at a destination device. A first reliable datagram service is established, with a first source and destination resource (SDR), between the source device and the destination device. A second reliable datagram service is established, with a second SDR independent of the first SDR, between the source device and the destination device. A first unit of work stream is transmitted over a communication services/fabric with the first reliable datagram service, which guarantees strong ordering of the first unit of work stream received at the destination device. A second unit of work stream is transmitted over the communication services/fabric with the second reliable datagram service, which guarantees strong ordering of the second unit of work stream received at the destination device.

Abstract: A method for controlling the throughput in a communications channel between a host and its storage subsystem is disclosed. A determination is made whether or not a total throughput value is greater than a predetermined maximum throughput value. If the total throughput value is greater than the predetermined maximum throughput value, a delay is applied to the communications channel. If the total throughput value is not greater than the predetermined maximum throughput value, another determination is made whether or not one time period has completed. If one time period has completed, a total throughput value and an exponential moving average (EMA) throughput value of the communications channel is retrieved, a new EMA throughput value is generated based on the total throughput value and the EMA throughput value, and adjusting the total throughput value based on whether or not the new throughput value is greater than a predetermined maximum throughput value.

Abstract: A method, apparatus, and program product that facilitates the implementation of grid or distributed network computing by automatically organizing a group of computers into a hierarchical, or tree networked system. The computer servers are selected into subgroups with each subgroup selecting a server to act as its leader. The leader is responsible for reporting performance characteristics of the servers in the subgroup to a master catalog server housed in a centralized management facility. The hierarchical system contemplated by embodiments of the invention reduces the number of messages that must be sent between the servers in the system necessary to monitor and manage the system. This reduction in the number of messages that must be sent between the servers in the system reduces the amount of server resources dedicated to overhead monitoring and managing, freeing these resources to be dedicated to performing the common processing task that grid or distributed network system was established to perform.
