20120106325Adaptive Shaper for Reliable Multicast Delivery over Mixed Networks - Improved handling of multicast streams in digital networks. A switching device in a digital network such as a controller, bridge, or access point examines streams flowing through the device. The device identifies a multicast stream and assigns a stateful session to this stream. QoS marking may be applied to the stream. The device assigns a shaping policy to the stream, assigning it a default value in terms of bandwidth credits. This default value may be dependent on the stream type. The credits used by the stream are evaluated periodically. If the stream has exceeded the allocated bandwidth for the shaping policy, the number of credits are increased by a predetermined factor. If the stream has unused credits, the allocated number of credits are reduced by a predetermined factor. The increase and decrease factors may be tuned, for example, to provide a fast attack and a slow decay. The period used for stream evaluation may be adjusted. Increasing the period decreases the load on the device CPU; decreasing the period allows for better convergence at a cost of more load on the CPU. This approach allows the packets in the stream to be released at a constant rate and allows transmission of bursty traffic over networks on which congestion conditions can change rapidly such as wireless and vpn tunnels. In addition, the potential for downstream drops due to the lack of buffers in downstream switch/routers due to the burstiness is reduced.05-03-2012

20100128604VIDEO STREAMING - The bitrate for any practical video streaming system will vary considerably as a function of the difficulty of encoding the sequence in question. This variation is even more apparent when comparing different video clips of different genres for example where sports clips might require a higher average bitrate and fluctuate more due to the high activity of typical scenes, whereas a news report clip might require a much lower bitrate and be relatively static.

The MAP IE includes an action code that requests the change of the status of the pFA, and a bit map representing an FA of which status is to be changed. When a response, which represents the completion of the change of the status of the pFA of the base station, is received from the terminal, the base station changes the status of the pFA and communicates with the pFA of the terminal through a new pFA. The status of a previous pFA between the base station and the terminal is changed into the status of the sFA, and the status of one previous sFA between the base station and the terminal is changed into the status of the pFA, so that communication is performed through new FAs. According to the present invention, since the base station can change the status of a specific terminal and FAs in use according to need, it is possible to adjust loads between the FAs. Further, the base station can change the statuses of the FAs in use while continuously maintaining the access of a specific terminal.10-28-2010

20100226249ACCESS CONTROL FOR PACKET-ORIENTED NETWORKS - The invention relates to a method for access control to a packet-oriented network. An admissibility check for a group of packets is carried out by means of a threshold value for the traffic volume between the network input node and the network output node for the flow.

Within the above method a flexible reaction to the drop-out of links can be achieved by means of a resetting of the threshold values. Furthermore the inclusion of other conditions is possible, for example relating to the capacity of interfaces to other networks or special demands on transmission of prioritized traffic.09-09-2010
