    Abstract: A source host device masks the hardware address of a hosted container from a network device to mitigate the use of resources in the network device. A virtual switch on the source host receives a frame from a hosted container. The frame includes a source hardware address of the hardware address corresponding to the hosted container. The frame also includes a source network address of the network address corresponding to the hosted container. The virtual switch replaces the source hardware address of the frame with the hardware address associated with the source host, and send the frame to the network device. The frame sent to the network device includes the host hardware address as the source hardware address and the container network address as the source network address.

    Abstract: A monitoring session associated with a virtual nickname may be established in a TRILL network. A monitoring station may be connected to an edge switch of the TRILL network specifying the virtual nickname for the monitoring session. The monitoring station is set as a destination for the monitoring session and the virtual nickname is flooded throughout the TRILL network. A source may then be configured to the monitoring session by specifying the virtual nickname of the monitoring session without knowing the destination tied to the monitoring session. Network traffic through the source may then be forwarded to the destination tied to the monitoring session.

    Abstract: Techniques for virtual workload deployment based on computing resource hardware load and associated network hardware load. For each of a plurality of computing resources within one or more data centers onto which a virtual workload can be deployed, a computing resource hardware load of the respective computing resource is determined. Network topology information is maintained for at least one network fabric of the one or more data centers, and an associated network hardware load of a network device communicatively connected to the respective computing resource is determined. Embodiments automatically select one or more computing resources. The virtual workload is deployed onto the automatically selected one or more computing resources.

    Abstract: Embodiments include determining computing resources within one or more data centers onto which a virtual workload can be deployed. Network state data is determined for a plurality of network resources within a network fabric of a data center. For each of the plurality of computing resources, embodiments determine a respective suitability value describing a fitness of the respective physical server for deploying at least a portion of the virtual workload. Such a determination includes determining a respective at least one of the plurality of network resources within the at least one network fabric corresponding to the respective computing resource and determining a current workload of the at least one network resource, based on the network state data. Upon selecting one or more computing resources of the plurality of computing resources based on the determined suitability values, embodiments deploy the virtual workload onto the selected one or more computing resources.
