Abstract:
1. A method, implemented by programming on a suitable processor, of managing cluster interconnect traffic among a plurality of cluster nodes in a computer system, the method, comprising: at each cluster node, prioritising the cluster interconnect traffic using at least two priorities and placing data items of the prioritized cluster interconnect traffic in queues of respective priority levels; and distributing the prioritised cluster interconnect traffic according to the prioritizing, such that at each cluster node, the cluster interconnect traffic in a first priority class is distributed with at least one of a higher data rate and a lower latency than cluster interconnect traffic in a second priority class; wherein distributing comprises distributing predetermined amounts of traffic from the queues, and wherein the predetermined amount of traffic to be distributed from each queue is based on the priority level of each such queue with the predetermined amount of traffic distributed from a higher priority queue being greater than the predetermined amount of traffic from a lower priority queue.
