  • Patent number: 10926659
    Abstract: Adaptive charging networks in accordance with embodiments of the invention enable the optimization of electric design of charging networks for electric vehicles. One embodiment includes an electric vehicle charging network, including one or more centralized computing systems, a communications network, several, electric vehicle node controllers for charging several electric vehicles (EVs), where the one or more centralized computing systems is configured to: receive the electric vehicle node parameters from several electric vehicle node controllers, calculate a charging rates for the electric vehicle node controllers using quadratic programming (QP), where the quadratic programming computes the charging rates based on the electric vehicle node parameters, adaptive charging parameters and a quadratic cost function, and distributes the charging rates to the electric vehicle node controllers.

  • Patent number: 9253104
    Abstract: A method of controlling size of a receive window includes transmitting packets over a communication channel from a transmitting device to a receiver, and receiving acknowledgment packets from the receiver, the received acknowledgement packets from the receiver including an advertised receive window size. The method further includes determining a backlog parameter for the receiver in accordance with the advertised receive window size, determining a queuing delay in accordance the received acknowledgment packets, resetting a size of a congestion window in accordance with a function of a current size of the congestion window and a factor proportional to the queuing delay, and resetting a size of a receive window in accordance with a function of a current size of the receive window and the backlog parameter. A network window is reset in accordance with the smaller of the size of the congestion window and the size of the receive window.

  • Patent number: 8730799
    Abstract: A method of controlling size of a receive window includes, at a transmitting device, transmitting packets over a communication channel from the transmitting device to a receiver, receiving acknowledgment packets from the receiver corresponding to the transmitted packets, determining a backlog parameter for the receiver in accordance with a parameter value in the received acknowledgment packets, resetting the size of the receive window in accordance with a function of a current size of the receive window and the backlog parameter, and after the resetting, transmitting packets over the communication channel from the transmitting devices to the receiver in accordance with the reset size of the receive window.
