    • The claimed subject matter provides systems and/or techniques that identify service dependencies in enterprise networks. The system can include devices that, based on received network data packets, identify packets with common five tuples, aggregate the identified packets to form transactions associated with individual hosts, and determine delay distributions between one or more services solicited from or in response to the individual hosts. Based on the delay distributions, the system differentiates between dependent service pairs and independent service pairs and thereafter assembles and outputs dependency graphs that include dependency relationships between services from the perspective of a client-side and a server-side.
    • 所要求保护的主题提供了识别企业网络中的服务依赖性的系统和/或技术。 系统可以包括基于接收到的网络数据分组识别具有共同的五元组的分组的设备,聚合所识别的分组以形成与各个主机相关联的交易,并且确定从个人或从响应个人而引起的一个或多个服务之间的延迟分布 主机。 基于延迟分布,系统区分依赖服务对和独立服务对,然后从客户端和服务器端的角度组装并输出包括服务之间的依赖关系的依赖关系图。

    • A nanometer precision six-DOF magnetic suspension micro-stage and the application thereof are provided which are mainly used in semiconductor photolithography devices. The micro-stage includes a cross support and four two-DOF actuators. Each 2-DOF actuator comprises a vertically polarized permanent magnet, a horizontal force coil and a vertical force coil; the permanent magnet being mounted on an end of the cross support, the horizontal force coil and the vertical force coil being arranged on a side of and below the permanent magnet respectively and being spaced apart from the permanent magnet; the cross support and four vertically polarized permanent magnets constitute a mover of the micro-stage; the horizontal force coil and the vertical force coil being fixed by a coil framework respectively and constituting a stator of the micro-stage; and the stator being mounted on a base of the micro-stage. A dual-wafer table positioning system of a photolithography machine may be constructed by two said micro-stages in combination with a two-DOF large stroke linear motor. The present invention features simple structure, large driving force, small mass and absence of cable disturbance, and is possible to realize high precision, high acceleration six-DOF micro-motion.
