  • Publication number: 20140376367
    Abstract: The disclosure herein describes an edge device of a network for distributed policy enforcement. During operation, the edge device receives an initial packet for an outgoing traffic flow, and identifies a policy being triggered by the initial packet. The edge device performs a reverse lookup to identify at least an intermediate node that is previously traversed by the initial packet and traffic parameters associated with the initial packet at the identified intermediate node. The edge device translates the policy based on the traffic parameters at the intermediate node, and forwards the translated policy to the intermediate node, thus facilitating the intermediate node in applying the policy to the traffic flow.

  • Patent number: 8917632
    Abstract: Some embodiments provide a method for encoding video pictures captured by a mobile device having at least first and second cameras. The method identifies a first rate controller parameter that is based on at least a first value that quantifies one characteristic of the first camera. The method uses the first rate controller parameter to configure a set of rate controllers to adjust a bit rate for encoding video pictures captured by the first camera. The method identifies a second rate controller parameter that is based on at least a second value that quantifies the same characteristic of the second camera. The first and second values are different, and the difference causes the first and second rate controller parameters to be different. The method uses the second rate controller parameter to configure the set of rate controllers to adjust a bit rate for encoding video pictures captured by the second camera.
