在传输网络故障的情况下自动复位预编程电路的系统和方法
Abstract:
一种网络系统包括至少一个输入TNE(10)和一个输出TNE(11)，它们通过网络(20)中的电路互连。每个TNE在保护步骤中包括通信量选择器(22，23)和分路模块(21，24)，所述通信量选择器(22，23)可在监听从工作电路(13，14)输入的通信量和监听从复位电路(18，19)输入的通信量之间切换，所述分路模块(21，24)允许发送输出到工作电路或复位电路的相同通信量。每个TNE另外包括称为ASTN代理的代理(25，26)，所述代理命令激活和停用复位电路以及在工作电路和复位电路之间切换通信量选择器。两个ASTN代理中的每个能够发出：“激活”消息，以命令激活复位电路并用信号通知另一个代理完成对复位电路的激活；以及“回复请求”消息，用于用信号通知另一个代理希望停用先前激活的复位电路；以及“回复”消息，用于在接收到由另一个代理发送给它的“回复请求”消息后，命令停用复位电路。
Abstract(English):

A network system comprises at least one input TNE (10) and one output TNE (11) interconnected by circuits in the network (20). Each TNE in the protection step comprises a traffic selector (22, 23) switchable between listening to the traffic input from a work circuit (13, 14) and listening to the traffic input from a reset circuit (18, 19) and a Split module (21, 24) allowing sending of a same traffic output either to a work circuit or to a reset circuit. Each TNE comprises in addition an agent (25, 26) termed ASTN agent commanding activation and deactivation of the reset circuit and switchingof the traffic selector between work circuit and reset circuit. Each of the two ASTN agents can emit an 'Activate' message to command activation of the reset circuit and signal to the other agent completed activation of the reset circuit and a 'RevertRequest' message for signaling to the other agent the desire to deactivate the reset circuit previously activated, and a 'Revert' message for commanding deactivation of the reset circuit after reception of a 'RevertRequest' message sent to it by the other agent.
