    摘要： One networking device includes a switch module, a server, and a switch controller. The switch module has ports with a communications interface of a first type (CI1) and ports with a communications interface of a second type (CI2). The server, coupled to the switch module via a first CI2 coupling, includes a virtual CI1 driver, which provides a CI1 interface in the server, defined to exchange CI1 packets with the switch module via the first CI2 coupling. The virtual CI1 driver includes a first network device operating system (ndOS) program. The switch controller, in communication with the switch module via a second CI2 coupling, includes a second ndOS program controlling, in the switch module, a packet switching policy defining the switching of packets through the switch module or switch controller. The first and second ndOS programs exchange control messages to maintain a network policy for the switch fabric.

    摘要： Methods, systems, and computer programs are presented for managing a global network topology. One method includes an operation for generating, by a network device, a local topology identifying which network entities are connected to each external port of the network device. The network device is configured to execute a network device operation system (ndOS), and the network device is configured to share information associated with the local topology with other ndOS network devices that execute ndOS. Further, the method includes an operation for receiving one or more remote local topologies from respective one or more ndOS network devices. The network device generates a global topology based on the local topology and the one or more remote local topologies, where the global topology is shared by the network device and the ndOS network devices executing ndOS, and the global topology identifies which entities are connected to one or more of the ndOS network devices.

    摘要： Methods, systems, and computer programs are presented for managing network switching. A network device operating system (ndOS) program includes instructions for exchanging switching policy regarding switching network packets in a plurality of ndOS devices having ndOS programs. The first ndOS program is executed in a first ndOS device, and the switching policy is exchanged with other ndOS programs via multicast messages. Further, the ndOS program includes instructions for exchanging resource control messages with the other ndOS devices to implement service level agreements in the switching fabric, where the ndOS switching devices cooperate to enforce the service level agreements. Further yet, the ndOS program includes instructions for receiving changes to the switching policy, and instructions for propagating the received changes to the switching policy via message exchange between the ndOS programs. The ndOS devices are managed as a single logical switch that spans the plurality of ndOS devices.

    摘要： Systems, methods, and computer programs are presented for managing network traffic. A network switch includes a switch fabric and a resource coherency and analytics engine (RCAE) coupled to the switch fabric. The RCAE includes one or more virtualizable resource groups (VRGs) for managing network traffic flow across a plurality of network switches on the network. Further, the RCAE is operable to add network entities to each VRG, add flows to each VRG, and add other VRGs to each VRG. A virtualizable resource control list (VRCL), associated with each VRG, identifies which network entities in the VRG can communicate with each other, which network entities in the VRG can communicate with network entities in other VRGs, and a guaranteed bandwidth for the VRG associated with the VRCL. Furthermore, the RCAE is operable to exchange messages with other RCAEs in other network switches to implement traffic policies defined by each VRCL.

    摘要： Methods, systems, and computer programs are presented for managing a network in the presence of layer-2 loops. One method includes an operation for detecting, by a network device, a loop at a layer 2 of a network. The network device is configured to execute a network device operation system (ndOS), where network devices executing ndOS share a global switch table. The method further includes an operation for blocking ports associated with the loop where incoming packets received at the blocked ports are discarded except for loop-probe packets. Further, the method includes operations for sending loop-probe packets by one or more network devices executing ndOS through one or more ports, and for unblocking a first port of the blocked ports based on the loop-probe packets when a lack of receipt of a loop-probe packet within a predetermined amount of time is detected for the first blocked port which indicates that the first blocked port is not part of the loop.
