Abstract:
1. A method for managing packet traffic in a data processing network, the network being comprised of a plurality of nodes interconnected via an interconnect comprising a plurality of switches and interconnecting links, comprising: collecting data indicative of the amount of packet traffic traversing selected links by collecting packet data for each switch in the interconnect; generating a data table for each switch, wherein each data table includes an entry for each link pair associated with the switch, wherein each entry indicates the number of packets traversing the corresponding link pair during a monitored period, wherein each link pair entry corresponds to a unique combination of an input link and output link associated with the switch; identifying, from the collected data, a heavily used link; analyzing the collected data for the heavily used link to identify a source node and a destination node combination that contributes to the traffic on the heavily used link, wherein analyzing the collected data comprises identifying the most common combination of source and destination information associated; and migrating a process associated with the identified source and destination combination wherein packets generated by the migrated process traverse a path from source to destination that consists of links other than the heavily used link, wherein migrating a process associated with a source and destination combination includes migrating the process to a different source node, wherein a path connecting the different source node and the destination node does not include the heavily used link.
