  • Publication number: 20150062285
    Abstract: Method, device and apparatus for delivering video telephony by using a media controller and a software defined networking (SDN) controller to enable multicasting for multi-party video conferencing. A media controller generates a video sending rate for each of the plurality of client devices based on a received video conference request and received network information. The media controller determines and independently constructs a maximum-rate delay-bounded multicast tree for each of the plurality of client devices that supports the largest possible multicast rate. The media controller determines a common congested link in the multicast trees, re-routes the multicast tree with the common congested link for the client device with the lowest weight of utility divided by its video sending rate and creating two subtrees, and iteratively re-routes the multicast trees until an aggregate video sending rate of the multicast trees sharing the common congested link meets a link capacity of the common congested link.

  • Publication number: 20150063112
    Abstract: A QoS management scheme for SDN. Network resource availability of routers and switches are maintained in a central resource database of a SDN controller. The SDN controller performs resource reservation, admission control and route calculation. When a flow is admitted or completed, the resource database is updated accordingly. Dynamic queue mapping for QoS routing in SDN is also provided. For a traffic flow with a certain traffic description and delay requirement, the queue mapping protocol dynamically assigns the flow to different priority queues at different switches along its routing path. Compared with the static mapping of a flow to a specified priority queue, the disclosed mapping is more flexible and uses network resources more efficiently.

  • Patent number: 8731236
    Abstract: An embodiment of an apparatus to authenticate a sequence of video frames includes a process to choose intra-frames of the sequence and sample DC components thereof to produce a set of test fingerprints. To reduce a dimensionality of the test fingerprints, the DC components of the chosen intra-frames are multiplied by a projection matrix formed of eigenvectors associated with the larger eigenvalues of a covariance matrix for a library of frames. The projected test fingerprints are compared against a reference set of fingerprints for authentication. Time-stamp spacings of the chosen intra-frames are determined, and these spacings are employed to select candidate frames for authentication in the reference set of fingerprints.
