Abstract: A system and method can support routing packets between a plurality of switches in a middleware machine environment, thereby supporting Internet Protocol (IP) based management traffic via enabling IP over Infiniband (IPoIB) communication in the middleware machine environment. The plurality of switches can perform routing for inter-switch traffic in the middleware machine environment using a first routing algorithm. Then, a switch in the middleware machine environment can be selected as a hub switch for inter-switch traffic that can not reach destination using the first routing algorithm. Furthermore, a routing table associated with the hub switch can be updated when a path exists between a source switch and a destination switch via the hub switch.

Abstract: A system and method can rout traffic between distinct subnets in a network environment. A router that connects the distinct subnets, such as InfiniBand (IB) subnets, can receive a list of destinations that the router is responsible for routing one or more packets to. Then, the router can generate a random number based on a source local identifier (LID) and a destination LID associated with the one or more packets, and use a modulo based hash to select one router port from a plurality of output router ports of the router.

Abstract: Systems and methods for providing multicast group (MCG) membership relative to partition membership in a high performance computing environment. In allowing a subnet manager of a local subnet to be instructed that all ports that are members of the relevant partition should be set up as members for a specific multicast group, the SM can perform a more efficient multicast-routing process. It is also possible to limit the IB client interaction with subnet administration conventionally required to handle join and leave operations. Additionally, subnet manager overhead can be reduced by creating a spanning tree for the routing of multicast packets that includes each of the partition members added to the multicast group, instead of creating a spanning tree after each multicast group join request is received, as conventionally required.

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.

Abstract: Systems and methods are provided for supporting scalable multi-homed routing for virtual switch based host channel adapter (HCA) virtualization in a subnet. An exemplary method can provide one or more switches, a plurality of host channel adapters, a plurality of hypervisors, and a plurality of virtual machines. The method can arrange the plurality of host channel adapters with one or more of a virtual switch with prepopulated local identifiers (LIDs) architecture or a virtual switch with dynamic LID assignment architecture. The method can further perform a multi-homed routing for the subnet, wherein at least one of the plurality of host channel adapters comprises two virtual switches, wherein the two virtual switches are treated as endpoints of the subnet, and wherein the multi-homed routing for the subnet ensures that each the two virtual switches are routed through independent paths.

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: Systems and methods for supporting dual-port virtual router in a high performance computing environment. In accordance with an embodiment, a dual port router abstraction can provide a simple way for enabling subnet-to-subnet router functionality to be defined based on a switch hardware implementation. A virtual dual-port router can logically be connected outside a corresponding switch port. This virtual dual-port router can provide an InfiniBand specification compliant view to a standard management entity, such as a Subnet Manager. In accordance with an embodiment, a dual-ported router model implies that different subnets can be connected in a way where each subnet fully controls the forwarding of packets as well as address mappings in the ingress path to the subnet.

Abstract: Systems and methods to use all incoming multicast (MC) packets as a basis for global unique identifier (GUID) to local identifier (LID) cache contents in a high performance computing environment, in accordance with an embodiment. Since all multicast packets have a Global Route Header (GRH), there is always both a source GID and a source LID defined for an incoming multicast packet. This implies that it is, in general, possible for an HCA implementation to gather information about GID and GUID to LID mappings for any sender node based on all incoming MC packets.
