摘要： The present invention relates to a queue management unit and method for streaming video packets in a wireless network. The method includes determining a type of frame from a header of a video packet received at a transmit buffer. The method further includes discarding the received frame if the received frame is dependent upon any previously discarded frame, otherwise storing the received frame in one of a plurality of sub-queues of the transmit buffer according to the type of frame, where each sub-queue of the plurality of sub-queues stores frames corresponding to one type of frame. Also, the method includes creating space in the transmit buffer if there is insufficient space for a higher priority frame by discarding lower priority frames, as well as discarding frames in the transmit if the received frame is delayed more than a maximum period of time.

摘要： A method and apparatus for preserving the video quality of encoded video signals when transmitted over a communications network. The video signals may comprise Motion Picture Experts Group (MPEG) encoded video signals and the communications network may comprise a WiMAX or an LTE network. Illustratively, an MPEG encoded video signal is decomposed into three component video streams made up of I-frames, P-frames and B-frames, respectively. The three video streams may then be independently transmitted as separate and independent flows with different Quality of Service (QoS) levels. For example, the video stream comprising I-frames may be assigned a highest QoS level, while the video stream comprising B-frames may be assigned a lowest QoS level (with the video stream comprising P-frames assigned a QoS level therebetween). A receiver at the receiving end receives the independently transmitted video streams and combines them together to reproduce the encoded video signal.
摘要翻译：一种用于在通过通信网络传输时保持编码视频信号的视频质量的方法和装置。视频信号可以包括运动图像专家组（MPEG）编码的视频信号，并且通信网络可以包括WiMAX或LTE网络。说明性地，将MPEG编码视频信号分解为由I帧，P帧和B帧组成的三个分量视频流。然后可以将三个视频流独立地作为具有不同服务质量（QoS）级别的独立且独立的流来发送。例如，包括I帧的视频流可以被分配最高的QoS等级，而包括B帧的视频流可以被分配最低的QoS级别（其中包括在其间分配了QoS级别的P帧的视频流）。接收端的接收机接收独立发送的视频流并将它们组合在一起以再现编码的视频信号。

摘要： The invention comprises a method and apparatus that prevents the activation of a congestion controlling process that would otherwise be activated in response any packet loss condition. The congestion controlling process is inhibited when a congestion parameter associated indicates that the packet loss condition is not caused by congestion.

摘要： The invention comprises a method and apparatus for determining a network connectivity in a network having a plurality of nodes. In particular, one embodiment of the method includes generating a candidate link for each of a plurality of node pairs, predicting a performance of each candidate link by evaluating an expected impact of at least one condition on each candidate link, and determining the network topology using the predicted performances of the candidate links. The performance of each candidate link may be predicted by identifying at least one condition, determining the expected impact of the at least one condition on the candidate link, and predicting the performance of the candidate link by adjusting an expected performance of the candidate link using the expected impact of the at least one condition on the candidate link.
