    Abstract: A method is provided in one example and includes broadcasting a switching node identifier associated with a first link-state protocol enabled switching node to a plurality of link-state protocol enabled switching nodes. The plurality of link-state protocol enabled switching nodes are in communication with one another by a link-state protocol cloud. The method further includes broadcasting a priority associated with the first link-state protocol enabled switching node to the plurality of link-state protocol enabled switching nodes. The method further includes broadcasting connectivity information of the first link-state protocol enabled switching node to the plurality of link-state protocol enabled switching nodes using the link-state protocol cloud. The connectivity information includes connectivity of the first link-state protocol enabled switching node with at least one spanning tree protocol enabled switching node.

    Abstract: In an embodiment, a method comprises: detecting a change in a multiple-switch configuration in a data communications network comprising a plurality of packet data switches configured as roots of multicast trees. In response to detecting that the multiple-switch configuration has changed, a first value, a second value and a third value representing limits on a number of multicast trees supported in the network and prioritization of the switches are retrieved. The method further comprises determining a type of the multiple-switch configuration change. In response to determining that the type indicates that a first switch was added to the multiple-switch configuration, using at least the first, second and third values, it is determined whether to configure the first switch as a first root in the multiple-switch configuration. The method is performed by one or more computing devices.

    Abstract: This disclosure describes techniques for collecting network parameter data for network switches and/or physical servers and provisioning virtual resources of a service on physical servers based on network resource availability. The network parameter data may include network resource availability data, diagnostic constraint data, traffic flow data, etc. The techniques include determining network switches that have an availability of network resources to support a virtual resource on a connected physical server. A scheduler may deploy virtual machines to particular servers based on the network parameter data in lieu of, or in addition to, the server utilization data of the physical servers (e.g., CPU usage, memory usage, etc.). In this way, a virtual resource may be deployed to a physical server that has an availability of the server resources, but also is connected to a network switch with the availability of network resources to support the virtual resource.
