    摘要： To partition a distributed fabric system, at least one system port is allocated to each switching domain of multiple non-overlapping switching domains in a distributed fabric system. Multiple different look-up tables are produced, wherein each look-up table corresponds to a different switching domain of the multiple non-overlapping switching domains in the distributed fabric system. Each system port is associated with the look-up table of the multiple look-up tables that corresponds to the switching domain to which that system port is allocated. The look-up table associated with each system port has at least one table entry for each other system port allocated to the same switching domain as that system port.

    摘要： In a distributed network environment, a first virtual machine sends a first virtual machine control information to a first network system. The first network system sends a first control information to a first network control system in response to receiving the first virtual machine control information. The first network control system sends a portion of the first control information to a number of network systems. The first network control system sends a second control information to the first network system. The first virtual machine sends a first packet to the first network system which generates a unicast packet using a portion of the first packet and a portion of the second control information. A second network system receives and processes the unicast packet. The second network system sends a copy of the processed unicast packet to a second virtual machine associated with a second tenant.

    摘要： A switch includes network ports and a network processor with a fabric interface that provides SerDes (Serializer/Deserializer) channels. The network processor divides each packet received over the network ports into cells and distributes the cells across the SerDes channels. Fabric ports of the switch communicate with the fabric interface to transmit cells to and receive cells from the fabric interface. The switch is selectively configurable as a standalone switch by connecting each fabric port of the switch to another of the fabric ports of the switch, as a member of a switch stack by connecting each fabric port of the switch to a different other switch through one fabric port of that other switch, or as a member of a distributed fabric system by connecting each fabric port of the switch to a different scaled-out fabric coupler (SFC) chassis by an SFC fabric port of that SFC chassis.

    摘要： A network includes a first switching domain having a distributed fabric comprised of interconnected standalone switches. The standalone switches communicate with each other in accordance with a packet-based distributed fabric protocol. A second switching domain has a plurality of cell-based switches in communication with a cell-based switch fabric. The cell-based switches communicate with each other through the cell-based switch fabric in accordance with a cell-based distributed fabric protocol. One of the cell-based switches is coupled by a communication link to one of the standalone switches of the first switching domain. The second switching domain includes a server device coupled to one of the cell-based switches. The server device is configured with logic to process control packets for the standalone switches in accordance with the packet-based distributed fabric protocol and control packets for the cell-based switches in accordance with a protocol that is different from the packet-based distributed fabric protocol.

    摘要： Embodiments of the invention provide a method for load balancing a networking system comprising multiple computing nodes. The method comprises maintaining one or more data sets on at least one computing node. The method further comprises receiving, from each computing node, a load information unit for the computing node, wherein the load information unit relates to resource usage on the computing node. For each computing node, the method determines whether the load information for the computing node exceeds a corresponding load threshold for the computing node. A data set on at least one computing node is transferred to another computing node when the load information for the at least one computing node exceeds a corresponding load threshold for the at least one computing node.
