Abstract: Methods and systems for supporting efficient load balancing among a plurality of switches and a plurality of end nodes arranged in a tree topology in a network environment. The methods and systems can sort the plurality of end nodes, wherein the plurality of end nodes are sorted in a decreasing order of a receive weight. The method and system may further route, in the decreasing order of receive weights, the plurality of end nodes, wherein the routing comprises selecting at least one down-going port and at least one up-going port. Further, the method and system can increase an accumulated downward weight on each selected down-going port by the receive weight of the routed end node, and increase an accumulated upward weight on each selected up-going port by the receive weight of the routed end node.

Abstract: A system and method can support partition-aware routing in a multi-tenant cluster environment. An exemplary method can support one or more tenants within the multi-tenant cluster environment. The method can associate each of the one or more tenants with a partition of a plurality of partitions. The method can then associate each of the plurality of partitions with one or more nodes of a plurality of nodes, each of the plurality of nodes being associated with a leaf switch of a plurality of switches, the plurality of switches comprising a plurality of leaf switches and a plurality of root switches. Finally, the method can generate one or more linear forwarding tables, the one or more linear forwarding tables providing isolation between the plurality of partitions, wherein each of the plurality of nodes is associated with a partitioning order.

Abstract: A system and method for supporting load balancing in a multi-tenant cluster environment, in accordance with an embodiment. One or more tenants can be supported and each associated with a partition, which are each in turn associated with one or more end nodes. The method can provide a plurality of switches, the plurality of switches comprising a plurality of leaf switches and at least one switch at another level, wherein each of the plurality of switches comprise at least one port. The method can assign each node a weight parameter, and based upon this parameter, the method can route the plurality of end nodes within the multi-tenant cluster environment, wherein the routing attempts to preserve partition isolation.

Abstract: Systems and methods are provided for supporting efficient reconfiguration of an interconnection network having a pre-existing routing. An exemplary method can provide a plurality of switches, a plurality of end nodes, and one or more subnet managers, including a master subnet manager. The method can calculate, via the master subnet manager, a first set of one or more leaf-switch to leaf-switch multipaths. The method can store this first set of one or more leaf-switch to leaf-switch multipaths at a metabase. The method can detect a reconfiguration triggering event, and call a new routing for the interconnection network. Finally, the method can reconfigure the network according to the new routing for the interconnection network.
