得到多台同步计算机的外部时钟
摘要：
一种系统(10)，包括至少一个主馈电系统(12)，配电总线(14)，多个电力电路开关或断流器，这里也称作断路器(CB)(16)，以及至少一个负载(18)，例如电动机，焊接机，计算机，加热器，照明设备，和/或其他电气设备。使用中，将电力从能源供给主馈电系统(12)，即，例如开关板。该能源诸如从例如核反应堆，烧煤锅炉，燃气轮发电机以及柴油发电机获得动力的蒸汽涡轮机。供给主馈电系统(12)的电力使用断路器(16)分成多个支路，断路器(16)将电力提供给工业企业中的各种负载(18)上。另外，在各支路中提供断路器(16)以有助于保护设备，即，负载(18)，该负载(18)连接在各支路中。
摘要（英）：

A method and apparatus for monitoring a communication network is provided. The network includes a plurality of node electronics units communicatively coupled to at least one central control processing unit through at least one network wherein each network includes a network switch. The method includes coupling a monitoring domain to the network, and receiving at least one of network traffic transmitted on at least one of the monitored links, and network traffic received on at least one of the monitored links through at least one monitoring link. The apparatus includes a plurality of node electronics units communicatively coupled to at least one central control processing unit through at least one network wherein each network includes a network switch, and wherein the apparatus comprises a monitoring domain.
