摘要： Techniques for improved routing based on network traffic are provided. Telemetry data relating to a first network node of a plurality of network nodes in a locator ID separation protocol (LISP) fabric is received. A first portion of the telemetry data that relates to a first destination of a plurality of destinations is identified. Further, a first routing weight associated with a first interface of the first network node is revised based on the first portion of the telemetry data, where the first interface is associated with the first destination. The revised first routing weight is published to a second plurality of network nodes in the LISP fabric, wherein the second plurality of network nodes route packets to the first network node based in part on the revised first routing weight.

摘要： The present invention is provides a method and apparatus for routing a data packet in a network. For each nearby device capable of routing the packet toward a further destination, an associated cost or utility is determined. The device with lowest cost or highest utility is selected and the packet is forwarded toward same. The selecting may use a comparator tree. The cost or utility may be associated with forwarding the data packet from the candidate device toward the further destination. The cost or utility may be based on a distance from candidate device to the further destination, and may be determined using a Haversine function or approximation thereof, or by computing an inner product of a first vector and a second vector originating at a center of Earth, the first vector directed toward the candidate device, the second vector directed toward the further destination.

摘要： Systems and methods for supporting target groups for congestion control in a private fabric in a high performance computing environment. An exemplary method can provide, at one or more microprocessors, a first subnet, the first subnet comprising a plurality of switches, a plurality of host channel adapters, and a plurality of end nodes, including a plurality of virtual machines. The method can define a target group on one of an inter-switch link or at a port of a switch of the plurality of switches, wherein the target group defines a bandwidth limit on the at least one of an inter-switch link between two switches of the plurality of switches or at a port of a switch of the plurality of switches. The method can provide a target group repository stored in a memory of the host channel adapter where the defined target group in the target group repository is recorded.

摘要： A rapid method for establishing communication routes between computers of a supercomputer is presented. In this method, a certain number of characteristics of the network are pre-calculated, which are then used for the calculation of the routes. The calculation is based on simple arithmetic operations which makes it possible to be particularly rapid while remaining deterministic.

摘要： System and method for supporting node role attributes in a high performance computing environment. In accordance with an embodiment, a node role attribute can comprise a vendor defined subnet management attribute. When a subnet manager attempts to discover a high performance computing environment, such as an InfiniBand subnet, or a switch topology, identifying a topology is quite complex when subnet manager can only observe connectivity, without context behind the connectivity (the roles of the different nodes in the connectivity). However, when a subnet has a node role attribute enabled, the subnet manager can map the interconnect more effectively as it can discover not only the connectivity during the initial sweep, but it can also discover the role of each node discovered, thus leading to a more efficient interconnect discovery.

摘要： Techniques are directed to determining a rank value associated with a first network node. An example method includes determining a second network node indicated as being a preferred parent network node for the first network node. A first rank value is processed to determine a second rank value, the first rank value corresponding to a path from the second network node to a destination network node, including rounding up the first rank value in a predetermined manner to at least a second next higher integral rank value than the first rank value, to determine the second rank value. The second rank value is processed with at least a third rank value to determine the rank value associated with the first network node, the third rank value associated with a path from one of a plurality of candidate parent network nodes, for the first network node, to the destination network node.
