    • A double visual-interface socket compliant with socket design rules set forth in the Digital Visual Interface standard comprises: a lower socket unit including plural L-shaped terminal pins; an upper socket unit disposed above the lower socket unit and including plural terminal pins; an adapter module including plural L-shaped pins arranged in rows; and a circuit board having plural terminal guide holes and plural extension guide holes. The terminal guide holes are inserted by, soldered to, and therefore electrically connected with the terminal pins of the upper socket unit, respectively. The extension guide holes are electrically connected with the terminal guide holes, respectively, and are inserted by, soldered to, and therefore electrically connected with ends of the L-shaped pins of the adapter module, respectively. The opposite ends of the L-shaped pins of the adapter module are substantially aligned with bottom ends of the L-shaped terminal pins of the lower socket unit.
    • 符合数字视觉接口标准中规定的插座设计规则的双视觉接口插座包括:下部插座单元,包括多个L形端子引脚; 上插座单元设置在下插座单元上方并且包括多个端子销; 适配器模块,包括排成行的多个L形销; 以及具有多个端子引导孔和多个延伸引导孔的电路板。 端子引导孔分别被插入,焊接到并因此与上部插座单元的端子引脚电连接。 延伸引导孔分别与端子引导孔电连接,并且分别插入,焊接到并因此与适配器模块的L形销的端部电连接。 适配器模块的L形销的相对端基本上与下部插座单元的L形端子销的底端对齐。

    • A system and method for measuring user-perceived delay in an IP network, comprising detecting request and corresponding response messages at a monitoring point in the network, calculating an uplink delay based upon the time elapsed between the request and corresponding response messages, detecting response and corresponding transport acknowledgement messages at the monitoring point, wherein the response message is sent in response to the request message, calculating a downlink network delay based upon the time elapsed between the response and corresponding transport acknowledgement messages; and calculating a user-perceived delay by adding uplink delay and downlink network delay, wherein the user-perceived delay represents a time required for an IP message to travel from a user device to a network destination plus the time required for the service (server) to respond and return the response to the user device.
    • 一种用于测量IP网络中的用户感知延迟的系统和方法,包括在网络的监控点检测请求和对应的响应消息,基于请求与相应响应消息之间经过的时间计算上行链路延迟,检测响应和 在所述监视点处的相应的传输确认消息,其中响应于所述请求消息发送所述响应消息,基于所述响应和相应的传输确认消息之间经过的时间计算下行链路网络延迟; 以及通过添加上行链路延迟和下行链路网络延迟来计算用户感知的延迟,其中用户感知延迟表示IP消息从用户设备移动到网络目的地所需的时间加上服务所需的时间(服务器) 以响应并将响应返回给用户设备。
