  • Patent number: 10318334
    Abstract: A VIRTIO Relay Program allows packets to be transferred from a Network Interface Device (NID), across a PCIe bus to a host, and to a virtual machine executing on the host. Rather than an OvS switch subsystem of the host making packet switching decisions, switching rules are transferred to the NID and the NID makes packet switching decisions. Transfer of a packet from the NID to the host occurs across an SR-IOV compliant PCIe virtual function and into host memory. Transfer from that memory and into memory space of the virtual machine is a VIRTIO transfer. This relaying of the packet occurs in no more than two read/write transfers without the host making any packet steering decision based on any packet header. Packet counts/statistics for the switched flow are maintained by the OvS switch subsystem just as if it were the subsystem that had performed the packet switching.

  • Patent number: 10255151
    Abstract: A smart add-in card can be leveraged to perform testing on a host server computer. The add-in card can include an embedded processor and memory. Tests can be downloaded to the add-in card to test a protocol under which the add-in card operates. In a particular example, a PCIe communication bus couples the motherboard to the add-in card and the tests can purposely violate the PCIe specification. The tests can be developed to test conditions that are typically difficult to test without the use of special hardware. However, the smart add-in card can be a simple Network Interface Card (NIC) that resides on the host server computer during normal operation and is used for communication other than security testing. By using the NIC as a testing device, repeatable and reliable testing can be obtained.

  • Patent number: 10157092
    Abstract: Techniques described herein relate to automatic system suspension based upon downstream system failure in service-oriented architecture (SOA) applications. A system management module of a SOA system may be configured to detect a problem with a downstream service provider involved with a SOA application, and in response, automatically suspend particular processing within the application to prevent requests that may end up at the downstream service provider from entering the SOA application. The system management module may implement a circuit breaker module that maintains a circuit breaker structure specific to a downstream endpoint leading to a downstream service provider. Upon a triggering of a circuit breaker for a downstream endpoint, one or more upstream service providers are identified as associated with faulted traffic causing the triggering, and the system management module can automatically cause further traffic from these upstream service providers to be suspended.

  • Patent number: 10044552
    Abstract: A system and method of distributed computation based upon a novel partitioning of computer networks. In the distributed computing system of the present invention, instructions are disseminated to select agents on a computer network, each of which is a member of at least one “path,” a path being an ordered set of one or more connected agents within the network. The computation is then performed by the agents along the path, and any results then returned. A computation to be performed is broken down into instructions executed on a unique ordered sequence of agents making up a path. This vastly increases the expressive power of a single network to be not only the sum of its parts, but the sum of all possible configurations of those parts on a graph. The basic components of the computing system are agents, probes and paths. The agents are interconnected forming a network and a path is an ordered sequence of agents.

  • Patent number: 9807229
    Abstract: A minimum confidence level is applied to recognize a localizable wireless system debility from a debility which is invariant from place to place or which cannot be significantly distinguished from service performance levels of comparable mobile user terminals in the network as a whole. Reports received by the population of users of a service or product family are scored, aggregated, normalized, and averaged overall and for each geographic service area. A report is received from a particular end user and the customer operated wireless instrument and transformed into an individual user experience score over a length of time and breadth of locations. The reports provided by the population of users are transformed into a population experience score that reflects usage in the same time and locations reported from the wireless instrument of the particular end user. Various potential causations are considered and those which exceed a minimum level of confidence are presented.

  • Patent number: 9774506
    Abstract: The present invention relates to a method and apparatus for event analysis in a communication (telecommunication or computer) system. In particular, the invention relates to a method and apparatus for analyzing events representing activity in the communication system. Embodiments provide a progressive technique for the analysis of the operation of a communication system. Embodiments provide a bottom-up approach by first detecting burst of events, and establishing causal relationships between events and system operation reports using detected event burst records representing the occurrence of burst behaviors in events in a system. Based on the causal relationships found, causes of a change in system operation may be identified by determining parameters associated with events of an event burst relevant to the change in system operation.

  • Patent number: 9577911
    Abstract: A system and method of distributed computation based upon a novel partitioning of computer networks. In the distributed computing system of the present invention, instructions are disseminated to select agents on a computer network, each of which is a member of at least one “path,” a path being an ordered set of one or more connected agents within the network. The computation is then performed by the agents along the path, and any results then returned. A computation to be performed is broken down into instructions executed on a unique ordered sequence of agents making up a path. This vastly increases the expressive power of a single network to be not only the sum of its parts, but the sum of all possible configurations of those parts on a graph. The basic components of the computing system are agents, probes and paths. The agents are interconnected forming a network and a path is an ordered sequence of agents.
