Patent number: 10708148Abstract: Many services measure quality of service (QoS) according to abstract metrics based on general heuristics of QoS determinants (e.g., VoIP service providers may presume that QoS is predominantly determined by network performance). However, users' QoS perceptions are often based on their experiences with particular activities of the service, which may utilize different service paths having different QoS determinants. Therefore, QoS may be measured by identifying the activities of the service, and the dependencies among the components of such services; for respective activities and dependencies, identifying a service path from the source to the user, and the segments comprising the service path; measuring the quality of the segments of the service path; and calculating the QoS of the activity according to the QoS of the segments of the service path providing the activity. This approach may yield QoS information of greater relevance to the users' experience and with greater analytic value.Type: GrantFiled: September 12, 2011Date of Patent: July 7, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Chinna Polinati, Purushottam Shridhar Amradkar, Joan Ouyang, Arne Lynn Gaenz, Edward Ministerio Sarausad, Christine Jefson

Patent number: 10318334Abstract: 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.Type: GrantFiled: July 7, 2017Date of Patent: June 11, 2019Assignee: Netronome Systems, Inc.Inventors: Gysbert Floris van Beek van Leeuwen, Johann Heinrich Tönsing

Patent number: 10157092Abstract: 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.Type: GrantFiled: April 14, 2016Date of Patent: December 18, 2018Assignee: Oracle International CorporationInventors: Aninda Sengupta, Steven Gene Wolfangel, Philippe Le Mouel, Dennis Fuglsang, Lixin Tang, Sherry Weng, Bo Stern

Patent number: 10044552Abstract: 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.Type: GrantFiled: January 11, 2017Date of Patent: August 7, 2018Assignee: Black Cloud Analytics, Inc.Inventor: Robert L.
