    摘要： Embodiments are directed to an Autonomous System-based Edge Marking (ASEM) for Internet Protocol (IP) traceback. In particular, the embodiments are a system and a method for IP traceback that receives one or more packets at routers; inscribes packets only at marking routers with autonomous system (AS) level and marking information; and forwards the marked packets to edge routers and other routers for verification. Additionally the packets are marked based on a probability measure and Border Gateway Protocol (BGP) routing table information is the AS level information used for marking and verification.

    摘要： A method for producing a control output is described. The method includes identifying an error signal and decomposing the error signal into a plurality of signal components. The signal components are determined based on a plurality of orthogonal functions representing multi-resolution decomposition properties. The method further includes transforming each signal component. The transformed signal components are summed to determine a control signal.

    摘要： Multiple designs, systems, methods and processes for controlling a system or plant using an extended active disturbance rejection control (ADRC) based controller are presented. The extended ADRC controller accepts sensor information from the plant. The sensor information is used in conjunction with an extended state observer in combination with a predictor that estimates and predicts the current state of the plant and a co-joined estimate of the system disturbances and system dynamics. The extended state observer estimates and predictions are used in conjunction with a control law that generates an input to the system based in part on the extended state observer estimates and predictions as well as a desired trajectory for the plant to follow.

    摘要： Controller scaling and parameterization are described. Techniques that can be improved by employing the scaling and parameterization include, but are not limited to, controller design, tuning and optimization. The scaling and parameterization methods described here apply to transfer function based controllers, including PID controllers. The parameterization methods also applies to state feedback and state observer based controllers, as well as linear active disturbance rejection controllers. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the application.

    摘要： Embodiments are directed toward a method for Behavior-based Traffic Differentiation (BTD) that initially receives incoming packets and performs traffic classification to determine the protocol of the incoming packets. In addition, BTD performs bandwidth division/allocation to further support traffic classification amongst non-TCP traffic such as UDP and ICMP. For TCP traffic, the method for BTD determines whether a TCP connection has been established and performs at least one of rate limiting, waiting time reduction for half-open connections, and incrementing backlog queue size when the TCP connection has not been established. If the TCP connection has been established successfully, the method for BTD further includes proactive tests for traffic differentiation which identify normal traffic, which is admitted, and attack traffic, which is dropped.

    摘要翻译： 实施例针对基于行为的流量分化（BTD）的方法，该方法最初接收传入分组并进行流分类以确定输入分组的协议。 此外，BTD执行带宽划分/分配，以进一步支持诸如UDP和ICMP之类的非TCP流量之间的流量分类。 对于TCP流量，BTD的方法确定TCP连接是否已经建立，并且在TCP连接尚未建立时执行速率限制，半开连接的等待时间减少以及递增积压队列大小中的至少一个。 如果TCP连接建立成功，BTD的方法还包括进行流量分类的主动测试，识别被允许的正常流量和丢弃的攻击流量。
