Abstract: A network device includes Power-over-Ethernet PoE ports to communicate with a communication network and Universal Serial Bus (USB) devices. The network device establishes an Internet Protocol (IP) related connection with an application program, and receives downlink IP packets carrying USB transaction requests destined for the USB device from the application program over the IP connection. The network device converts the received downlink IP packets carrying the USB transaction requests to downlink bus-level USB transactions that are understandable to the USB device. The network device sends the downlink bus-level USB transactions to the USB adaptor device over a PoE connection for forwarding by the USB adaptor device to the USB device.

Abstract: Techniques are presented herein for providing a persistent external Internet Protocol (IP) address for extra-cluster services. One example involves initiating, in a cluster, a first pod with a label that identifies a service. The first pod is configured to provide the service to one or more network entities outside the cluster. The first pod is assigned an IP address configured for communicating outside the cluster. A mapping of the service to the IP address is stored. In response to a determination that the service has been disrupted, a second pod is initiated in the cluster with the label that identifies the service. The second pod is configured to provide the service to the one or more network entities outside the cluster. Based on the mapping and the label that identifies the service, the IP address is assigned to the second pod.

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: Control plane analytics and policing may be provided. First, packets that traverse a port may be parsed. Next, based on the parsed packets, metrics for each of a plurality of hosts on a per-protocol basis may be created. The created metrics may then be analyzed and at least one restriction on at least one of the plurality of hosts may be applied based on the analysis.
