摘要： A system and method for multicast video streaming over a wireless local area network (WLAN) improves scalability and reliability. The method includes configuring the WLAN access point with a reserved video bandwidth (step 1005). A multicast video stream including data packets marked with differentiated services code points (DSCPs) is then received (step 1010). The multicast video stream is then converted to a plurality of “n” unicast streams (step 1015). Data packets in the unicast streams are then streamed from the WLAN access point to a plurality of “n” mobile units using a selective packet discard algorithm that employs the DSCPs (step 1020).

摘要： Methods and apparatus are provided for reliably transmitting data. A method comprises identifying a metric for a first frame of a plurality of frames, wherein the metric is indicative of decoding significance for the first frame among the plurality of frames. When the metric corresponds to a relatively high decoding significance, the method further comprises transmitting the first frame in accordance with an enhanced transmission scheme. When the metric corresponds to a relatively low decoding significance, the method further comprises transmitting the first frame in accordance with a default transmission scheme. The reliability of the enhanced transmission scheme is greater than the reliability of the default transmission scheme.

摘要： The method, apparatus and system of detecting whether a router is compromised and configured to place malicious packets onto the network are disclosed. In one embodiment, a method for detecting a malicious router includes performing hash on a current ingress packet received via the network packet payload to generate ingress packet hash values. Further, includes performing hash on current egress packet that is associated with the current ingress packet to generate egress packet hash values. The generated ingress packet hash values and the egress packet hash values are then compared. Then the router is checked to determine whether it is potentially compromised and configured to place the malicious packets based on the outcome of the comparison.

摘要： A method provides for differentiating usage permissions between different categories of communication traffic within a given network. The method includes ensuring one or more categories of traffic never transits communication radios, link, and/or spectrums dedicated to a different category of traffic. A combined routing metric is calculated using a scaling factor for discouraging usage of restricted communication links and encouraging usage of non-restricted communication links.

摘要： Disclosed are methods and systems for determining combinations of system parameters that indicate a root cause of a system level experience deterioration (SLED). Some of the disclosed embodiments generate a decision tree from a first class of operational parameter datasets. Rules are derived from the decision tree. Filtered rule sets for feature parameters included in the system parameters are then determined. Pairs of features within a particular dataset that each satisfy their respective filtered rule sets are indicative of a root cause of the degradation, at least in some embodiments.
