  • Patent number: 9455899
    Abstract: According to one embodiment, an apparatus includes a processor and logic integrated with and/or executable by the processor. The logic is configured to determine paths between a plurality of switches connected together in a system by performing path calculations based on a topology of the system. The logic is also configured to calculate one or more disjoint multi-paths from among the paths, the one or more disjoint multi-paths connecting a source device to a destination device. The source device is connected to a first switch of the plurality of switches, and the destination device is connected to a second switch of the plurality of switches. Moreover, the logic is configured to write the one or more disjoint multi-paths into a forwarding table of at least one device. Other systems and computer program products are presented according to more embodiments.

  • Patent number: 9185166
    Abstract: According to one embodiment, a data center fabric network system includes a controller, a plurality of switches connected to the controller via a plurality of communication links, a source device connected to at least a first switch of the plurality of switches, a destination device connected to at least a second switch of the plurality of switches, and wherein the controller is adapted for: creating a topology of the data center fabric network system, determining paths between the plurality of switches, calculating one or more disjoint multi-paths from the source device to the destination device based on the topology, and writing the one or more disjoint multi-paths into a forwarding table of at least one of: the source device, the first switch, and a nearest shared switch to the source device.

  • Patent number: 9166869
    Abstract: Management of a network may be provided by moving management functions from each switch in a network cluster into a locally controlled server. The management functions may be organized into an Ethernet distributed fabric switching protocol (E-DFP) based management plane. Control functions of each switch may also be organized into a control plane. The management plane and control plane of the network may be moved from each switch and integrated into the server. Efficiency in network switching may be provided by releasing the switches of their management and control responsibilities and centralizing these responsibilities to the server. In some embodiments, the server may be outside the cluster.
