20090192981 | Query Deployment Plan For A Distributed Shared Stream Processing System - A method of providing a deployment plan for a query in a distributed shared stream processing system includes storing a set of feasible deployment plans for a query that is currently deployed in the stream processing system. A query includes a plurality of operators hosted on nodes in the stream processing system providing a data stream responsive to a client request for information. The method also includes determining whether a QoS metric constraint for the query is violated, and selecting a deployment plan from the set of feasible deployment plans to be used for providing the query in response to determining the QoS metric constraint is violated. | 07-30-2009 |
20100278069 | Flow Path Discovery In Network To Guarantee Multiple Metric QoS Constraints - Route discovery for an end-to-end path in a network is performed for a flow. A path is attempted to be discovered that satisfies QoS constraints for multiple metrics for the flow. The route discovery includes determining whether a path request for a path satisfying the QoS constraints is feasible, infeasible or undecideable based on information in a local QoS table. If the path request is determined to be undecideable, route discovery is performed with neighbors. | 11-04-2010 |
20110055611 | SYSTEM FOR CONTROLLING POWER CONSUMPTION OF A NETWORK - A system for controlling power consumption of a network includes at least one terminal to receive a plurality of requests to route data from a plurality of data sources to a plurality of data sinks, where the data sources and the data sinks are connected to each other through a plurality of network nodes forming the network, and a network configuration unit. The network configuration unit includes a selection module configured to select a configuration of the network nodes that allows the network to have a lowest overall power consumption of the network among a plurality of configurations of the network, and an output module configured to output a plurality of instruction signals to the network nodes to perform the network configuration. A network path for transmitting a network flow is selected that does not allow the network flow to be split and flow through another network path. | 03-03-2011 |
20110196964 | MANAGING EVENT TRAFFIC IN A NETWORK SYSTEM - A network system and associated operating methods manage event storms. The network system comprises an event analysis and control engine that detects and manages events occurring on a network. The event analysis and control engine receives events from a plurality of agents, and analyzes the events according to policies specified in a policies templates database. The event analysis and control engine processes raw network packets directly with less than full packet parsing to generate a filtered stream of events based on the analysis. The event analysis and control engine propagates the filtered stream of events to a monitoring system. | 08-11-2011 |
20110261831 | Dynamic Priority Queue Level Assignment for a Network Flow - Forwarding a flow in a network includes receiving the flow at a switch, determining an optimized priority queue level of the flow at the switch, and forwarding the flow via the switch using an optimized priority queue level of the flow at the switch. The flow passes through a plurality of switches, including the switch, in the network, and the optimized priority queue level of the flow at the switch is different from a priority queue level of the flow at a second switch of the plurality of switches. The second switch routes the flow at the second switch using the different priority queue level for the flow. | 10-27-2011 |
20110273988 | Distributing decision making in a centralized flow routing system - Local rules for managing flows devolved from a central controller are received at a switch. The central controller determines a global set of rules for managing flows. The switch receives a packet from a flow from a network and determines whether a metric for the flow satisfies a dynamic condition to trigger a metric report to the central controller. In response to a determination that the metric for the flow at the switch satisfies the dynamic condition to trigger a metric report to the central controller, the switch sends a metric report to the central controller, and the switch then receives an instruction to manage the flow from the central controller. In response to a determination that the metric for the flow at the switch does not satisfy the dynamic condition to trigger the metric report to the central controller, the switch manages the flow using the local rules for managing flows. | 11-10-2011 |

20140153388 | RATE LIMIT MANAGERS TO ASSIGN NETWORK TRAFFIC FLOWS - A rate limit manager is to assign network traffic flows to hardware rate limiters. The network traffic flows are associated with rate limit values. The rate limit manager determines threshold values to assign flow(s) to hardware rate limiters, and the rate limit manager is to assign flow(s) to a last remaining unassigned hardware rate limiter independent of the threshold value. | 06-05-2014 |
20140258498 | Implementing an Energy Proportional Network Architecture from Desired Network Criteria - Systems, methods, and computer-readable executable instructions are provided for implementing an energy proportional network architecture. Implementing an energy proportional network architecture can include determining a number of desired network criteria and a desired number of access ports. A number of switches for the energy proportional network architecture can be calculated from the desired number of access ports and the number of desired network criteria. Implementing an energy proportional network architecture can also include using the number of calculated switches to form the energy proportional network. | 09-11-2014 |
20150019889 | Virtualizing Battery Across a Group of Personal Mobile Devices - A system, method, and non-transitory computer readable medium for virtualizing battery in a personal mobile device or across a group of personal mobile devices controlled by a user are provided. The user specifies a set of power management policies for applications running in the personal mobile device(s). Battery usage per application is monitored and resources for the applications are scheduled based on the monitored battery usage and the power management policies. | 01-15-2015 |
