摘要:
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.
摘要:
Distances are determined between an identified node and landmark nodes and milestone nodes in a network. The closest milestone or landmark node associated with a shortest of the measured distances is determined. A corresponding distributed hash table (DHT) overlay node is queried for distances between observed nearest nodes for the closest milestone or landmark node and the identified node. Distances between the identified node and the observed nearest nodes are calculated from distances received from the DHT overlay node and the measured distance to the closest milestone or landmark node. K-closest nodes from the identified node are selected from at least one of the closest milestone or landmark node and one or more of the observed nearest nodes based on the calculated distances.

摘要:
Allocating bandwidth in a network (100) may include reducing initial bandwidth allocations for each tenant on a link (113) such that a sum of the bandwidth allocations is equal to or less than a capacity of the link and distributing a residual of the initial bandwidth allocations to at least one under-allocated link (114).
摘要:
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.

A controller receives information from congestion detectors in a network, the information indicating that points in the network are congested due to data flows in the network. The controller controls data rates of the data flows based on the information.

摘要:
A request is received from a first node in a network. The request includes a request for a service node operable to provide a desired service. At least one service node is identified that is operable to provide the desired service based at least on location information for the first node.
摘要:
Network position information for a node in a network is determined. An infrastructure node in the network is identified for storing the network position information for the node based on a network distance to the infrastructure node.
摘要:
Nodes in a network are operable to provide an information service. A set of the nodes having a highest workload are identified by routing a list of workloads for the nodes through the network to a final destination. Each node receiving the list determines whether to include a workload of a respective node in the list.
