    摘要： A network management system utilizes an element manager at the RNC level to reduce the workload and efficiently manage multiple wireless appliances in a mobile data network. Management communications from the network management system flow through the element manager to all devices under the RNC level appliance hosting the element manager. The element manager provides for fault management, performance monitoring and configuration of the many breakout appliances and reports necessary information back to the network management system.

    摘要： Techniques are provided for implementing a zone-based firewall policy. At a virtual network device, information is defined and stored that represents a security management zone for a virtual firewall policy comprising one or more common attributes of applications associated with the security zone. Information representing a firewall rule for the security zone is defined and comprises first conditions for matching common attributes of applications associated with the security zone and an action to be performed on application traffic. Parameters associated with the application traffic are received that are associated with properly provisioned virtual machines. A determination is made whether the application traffic parameters satisfy the conditions of the firewall rule and in response to determining that the conditions are satisfied, the action is performed.

    摘要： An access point provisions of network resources at a data plane to optimize progressive downloads in WLANs. To do so, link information concerning at least one routing path of the access point is periodically sent to an SDN controller. As needed, download parameters are determined for a file transfer from the access point to a station from a resource external to the communication network. Responsive to the file transfer being a progressive download, one or more OpenFlow rules are received from the SDN controller. The one or more OpenFlow rules determine download parameters for the file transfer to the station based on link conditions visible to the SDN controller from the data plane of the communication network, including at least the access point link information periodically sent to the SDN controller. The file transfer to the station is then executed according to at least the one or more OpenFlow rules.

    摘要： An SDN controller to provision network resources at a data plane to keep progressive downloads of multimedia files proportional to encoding rates is disclosed. Packets from a new or unknown flow being downloaded at a default rate are forwarded from an access point, or other device, to an SDN controller for analysis. If a progressive download of a multimedia file (e.g., a video file) in progress is detected, an encoding rate of frames for the multimedia file is determined. A target download rate for the multimedia file at the access point is determined based on the encoding rate, in an embodiment. Other optional factors also take into account network-wide data plane information gathered by the SDN controller from various points on the network. Additionally, a playback history for a particular multimedia file can affect the target download rate, based on whether, for example, a file is likely to be quickly halted.
