摘要： An apparatus and method for a communications network including at least one interface circuit reads frame data received from the communications network and writes frame data to be transmitted over the communications network, the frame data including a plurality of transport overhead fields. The apparatus includes signature logic coupled to the interface circuit, the signature logic identifying signature data and writing the signature data into transport overhead fields in an outgoing frame. Reflector logic coupled to the interface circuit copies data from one of the received transport overhead fields, the copied data being placed into a transport overhead field in the outgoing frame, the copied data including the received signature data. The interface circuit compares the copied data to earlier received frame data from the communications network, the determination of a mismatch identifying a transition requiring an update of at least one routing table. The data is used to determine configuration compatibility between interfaces and among a plurality of tributary interfaces and to eliminate dependence on multiplexers that transmit to routers with protect circuits according to protection switching protocols. A method for a communications network includes transmitting signature data in a transport overhead field, the data identifying one of interfaces in the local routers, returning the data to the local router, and configuring a communications relationship using the data. The method includes using the data to determine which is an active interface and to determine whether to update at least one routing table and using the data to configure the interface circuits.
摘要翻译：一种用于包括至少一个接口电路的通信网络的装置和方法，读取从所述通信网络接收的帧数据，并写入要通过所述通信网络发送的帧数据，所述帧数据包括多个传输开销字段。该装置包括耦合到接口电路的签名逻辑，签名逻辑识别签名数据，并将签名数据写入输出帧中的传输开销字段。耦合到接口电路的反射器逻辑从接收的传输开销字段之一复制数据，复制的数据被放置在输出帧中的传输开销字段中，复制的数据包括接收到的签名数据。接口电路将复制的数据与来自通信网络的早期接收到的帧数据进行比较，确定标识需要更新至少一个路由表的转换的不匹配。该数据用于确定接口之间和多个支路接口之间的配置兼容性，并且消除对根据保护交换协议向具有保护电路的路由器发送到路由器的多路复用器的依赖。通信网络的方法包括在传输开销字段中传输签名数据，识别本地路由器中的接口之一的数据，将数据返回到本地路由器，以及使用该数据配置通信关系。该方法包括使用数据来确定哪个是活动接口并且确定是否更新至少一个路由表并使用数据来配置接口电路。
