  • Patent number: 11310571
    Abstract: The disclosed embodiments provide an optically switched network system. This system includes a passive optical switch with N inputs and N outputs, which can communicate different wavelengths from each of the N inputs to each of the N outputs. It also includes N end-nodes, and N pairs of optical fibers, wherein each pair connects one of the N end-nodes to one of the N inputs and one of the N outputs. The optically switched network is organized into a virtual data plane and a virtual control plane, which both communicate through the same underlying physical network. The virtual data plane provides any-to-all parallel connectivity for data transmissions among the N end-nodes. The virtual control plane is organized as a ring that serially connects the N end-nodes, wherein the ring communicates arbitration information among distributed-arbitration logic at each of the N end-nodes.

  • Patent number: 10868746
    Abstract: System and method for supporting intra- and inter-subnet address resolution in a network environment using the same linear forwarding tale (LFT) for both the intra- and inter-subnet forwarding. Subnet prefix values in global route headers (GRHs) are used for linear forwarding table (LFT) lookup in a high performance computing environments. An exemplary can provide for use of an Inter Subnet Route Number (ISRN) embedded in the subnet prefix values in the GRHs for LFT lookup in a network switch environment in a high performance computing environment such as a network having an InfiniBand (IB) architecture. A method can provide, at a computer environment, including a network fabric, one or more subnets, each of which subnets are associated with one or more network switches or hosts. The system and method is compatible with legacy switches and nodes that are not conversant with the ISRNs.

  • Patent number: 10602245
    Abstract: We disclose a method for controlling access to an optically switched network, which connects N end-nodes, and is organized into a virtual data plane and a virtual control plane, which both communicate through the same underlying physical optical network. The virtual data plane provides any-to-all parallel connectivity for data transmissions among the N end-nodes, and the virtual control plane is organized as a ring that serially connects the N end-nodes, wherein a control token circulates around the ring. During operation, an end-node in the ring receives the control token, which includes a destination-busy vector with a busy flag for each of the N end-nodes. If the end-node has data to send and the busy flag for the destination end-node is not set, the system: sets the busy flag; commences sending the data to the destination end-node; and forwards the control token to a next end-node in the ring.

  • Patent number: 10348649
    Abstract: System and method for supporting a partitioned switch forwarding table in a high performance computing environment. Described methods and systems can support partitioned switch forwarding tables (e.g., partitioned LFTs) by setting up hardware registers that divide the LFT into at least two partitions, a first partition that supports legacy forwarding (e.g., standard LID based forwarding without the need to use portions of the GRH), and a second partition to support the GRH based forwarding that is described above. In such a manner, switches and other hardware within a core fabric can behave as legacy nodes/switches having standard LFTs, while also being able to support the extended addressing supplied through the use of portions of the GRH.

  • Patent number: 10333894
    Abstract: System and method for supporting flexible forwarding domain boundaries in a high performance computing environment. In accordance with an embodiment, flexible forwarding domain boundaries can be supported by dividing/partitioning a physical switch into two or more logical switches, where each switch is logically in a different domain, and allowing a fabric to be decomposed into independent subnets with one two or more physical end ports at the physical switch. By doing so, the same hierarchical forwarding structure and management structure between subnets can be provided as when complete physical switches are used as building blocks.

  • Patent number: 10270713
    Abstract: A system for communicating a multi-destination packet through a network switch fabric with a plurality of input and output ports is described. This system receives the multi-destination packet at an input port, wherein the multi-destination packet includes a multicast packet or a broadcast packet that is directed to multiple output ports, and wherein the network switch fabric maintains a separate virtual output queue (VOQ) for each output port. Next, the system sends the multi-destination packet from the input port to the multiple output ports by inserting the multi-destination packet into VOQs associated with the multiple output ports. The multi-destination packet is inserted into one VOQ at a time, so that after the multi-destination packet is read out of a VOQ and is sent to a corresponding output port, the multi-destination packet is inserted in another VOQ until the multi-destination packet is sent to all of the multiple output ports.

  • Patent number: 10205550
    Abstract: An optically switched network system includes an optical switch with N inputs and N outputs that connects N end-nodes and is structured to transmit N wavelengths from each of the N inputs to each of the N outputs. The system includes a virtual data plane and a virtual control plane, which both communicate through the optical switch. The virtual data plane provides any-to-all parallel connectivity for data transmissions among the N end-nodes. The N end-nodes are partitioned into two or more subsets, wherein end-nodes in a given source subset transmit data to a given destination subset using wavelengths, which are not used by end-nodes outside of the given source subset to transmit data to the same given destination subset. The virtual control plane includes two or more rings associated with the two or more subsets of end-nodes. Each ring passes through a subset of end-nodes, and is used to communicate arbitration information among arbitration logic located at each end-node in the ring.
