Abstract: A host device is configured to communicate over a network with a storage system comprising a plurality of storage devices. The host device comprises a multi-path input-output (MPIO) driver configured to control delivery of input-output (IO) operations from the host device to ports of the storage system over selected ones of a plurality of paths through the network. The MPIO driver of the host device is further configured, for each of at least a subset of the ports, to obtain from the storage system information characterizing a current number of host devices connected to the port and a current available capacity measure of the port, and to limit an amount of the IO operations that are delivered over one or more of the paths to the port based at least in part on the obtained information.

Abstract: A network use optimization system may include a communication connection controller for being carried by a vehicle. The controller is configured to receive data signals from at least one data source, assign a data signal category to the data signals, and evaluate a current availability of each of a cellular data communications device and a radio frequency communications device. The controller is further configured to select one of the cellular data communications (CDC) device and the radio frequency communications (RFC) device for transmission of the data signals based on the current availability of each of the cellular data communications device and the radio frequency communications device and the category assigned to the data signals. The controller (1) outputs the selection to a person for confirmation and in response to a received confirmation, transmit the data signals using the selection or (2) automatically transmit the data signals using the selection.

Abstract: Systems and methods for social graph data analytics to determine the connectivity between nodes within a community are provided. A user may assign user connectivity values to other members of the community, or connectivity values may be automatically harvested or assigned from third parties or based on the frequency of interactions between members of the community. Connectivity values may represent such factors as alignment, reputation, status, and/or influence within a social graph of a network community, or the degree of trust. The paths connecting a first node to a second node may be retrieved, and social graph data analytics may be performed on the retrieved paths. For example, a network connectivity value may be determined from all or a subset of all of the retrieved paths. Network connectivity values and/or other social graph data may be outputted to third-party processes, services, and ratings agencies for use in initiating automatic transactions, making automated network-based or real-world decisions, determining or verifying the identity of a node within the community, scoring or ranking nodes, or making credit-granting decisions.

Abstract: Methods, systems, and computer storage media for providing a broadband data analytics object for a geographical region using a broadband data analytics engine in a data analytics system. The broadband data analytics object can be a computational object that is a representation of broadband service data for a geographical region, the broadband service data is associated with features of broadband availability and broadband expansion targeting constraints (e.g., geocoding, structure type, unit counts, and speed). The broadband data analytics engine is configured to generate the broadband analytics object for the geographical region based on a combination of broadband data analytics operations, data structures (e.g. targeted-building information model), and datasets (e.g., geospatial datasets, parcel data). The broadband data analytics operations can be associated with a broadband availability ruleset algorithm that supports implementing a waterfall analytics model for generating the broadband data analytics object that can be used for interpreting broadband service data.

Abstract: An example method according to some embodiments includes receiving flow data for a packet traversing a network. The method continues by determining a source endpoint group and a destination endpoint group for the packet. The method continues by determining that a policy was utilized, the policy being applicable to the endpoint group. Finally, the method includes updating utilization data for the policy based on the flow data.

Abstract: A method provides for receiving network traffic from a host having a host IP address and operating in a data center, and analyzing a malware tracker for IP addresses of hosts having been infected by a malware to yield an analysis. When the analysis indicates that the host IP address has been used to communicate with an external host infected by the malware to yield an indication, the method includes assigning a reputation score, based on the indication, to the host. The method can further include applying a conditional policy associated with using the host based on the reputation score. The reputation score can include a reduced reputation score from a previous reputation score for the host.

Abstract: Disclosed are a system comprising a computer-readable storage medium storing at least one program, and a computer-implemented method for event messaging over a network. An identification module receives first data identifying consumer devices available to receive event messages linked to a topic. The identification module receives second data identifying a producer device available to provide event messages linked to the topic. A provisioning module links a plurality of values to respective consumer devices that are linked to the topic. A scheduler module accesses a first data message linked to the topic. The first data message includes a key value. The scheduler module provides the first data message to a selected one of the consumer devices based on a comparison of the key value and the plurality of values of the respective consumer devices.

Abstract: An example method according to some embodiments includes receiving flow data for a packet traversing a network. The method continues by determining a source endpoint group and a destination endpoint group for the packet. The method continues by determining that a policy was utilized, the policy being applicable to the endpoint group. Finally, the method includes updating utilization data for the policy based on the flow data.

Abstract: To provide a transfer control apparatus, a transfer control method, and a transfer control program, by which it is possible to improve availability without modifying an application side. The transfer control apparatus 1 is an apparatus for dynamically switching enablers 2, and includes a registration unit 11 that registers enablers 2 having a similar function, in an identical genre, a monitoring unit 12 that monitors states of the enablers 2, and a transfer control unit 13 that transfers a request to an alternative enabler 2 registered in a genre identical to each of the enablers 2 to automatically switch a request destination if the enabler 2 is in a predetermined busy state upon calling the enabler 2.
