  • Patent number: 10129206
    Abstract: A device is configured to support one or more virtual networking functions at a branch in a network. The device receives from a central control entity a command to deploy a particular virtual networking function, the command including or accompanied by a deployment file that identifies an external port at which the particular virtual networking function is accessed externally at the device. The device maps the external port to an internal port on an internal management network of the device, and stores a portmapping entry for the particular virtual networking function based on the mapping. The device sends to the central control entity a notification containing portmapping information that indicates the internal port to which the external port is mapped.

  • Publication number: 20150127814
    Abstract: A monitoring server method includes the following steps. First, the baseboard management controller (BMC) receives the running status information of a system device transferred by the system management software. Then, the BMC determines whether or not the system device is operated in a normal state. When the system device is operated in an unusual state, the virtual sensor data record in the sensor data recorder is set in an abnormal state by the BMC. Then, the BMC generates an event according to the abnormal state to trigger a platform event filter (PEF) of the BMC to issue a warning signal to a remote management host.
