摘要： A network element is deployed in a network of interconnected elements. The network element includes a shared buffer multiplexer connected to a link, a set of regulators connected to the shared buffer mulitplexer, and an admission control unit communicatively coupled to the set of regulators and the shared buffer multiplexer. Each of the set of regulators has an input traffic flow. Each traffic flow has a varying flow rate. In order to control admission of the traffic flow to the link in the network element, the admission control unit evaluates the traffic flowing into each regulator. For each traffic flow, the admission control unit receives an envelope of the flow input to the regulator. The admission control unit maximizes the entropy of a distribution of the rate of flow over all time scales. The admission control unit determines the maximum-entropy distribution for the flow using information derived from the traffic envelope, including bounds of the mean rate, the minimum rate, and the maximum rate. The admission control unit approximates the rate variance of the maximum-entropy distribution for a given maximum rate. The admission control unit makes an admission control decision based on the approximated rate variance for the given maximum rate. If the flow is admitted, the flow is set up and transmission begins.

摘要： A system enhances communications security in a wireless local area network (WLAN). The system includes a multiple antenna array arranged to transmit and receive signals; and a transmitter/receiver coupled to the multiple antenna array and configured to transmit and receive the signals. The transmitter/receiver includes a beamformer, which in turn includes a signal processor component that generates a signal beam for transmission to an intended user, and a blinding component that computes one or more blinding beams using only channel state information of the intended user. The blinding beams have a zero inter-user interference condition with the signal beam. The transmitter/receiver transmits the signal beam and the blinding beams simultaneously
