Abstract: A network interface is disclosed for redundant coupling of a substation communication network and a packet-switched WAN of a power network. The interface device can include: a first redundancy module having: two LAN ports connectable with the Substation communication network, and a first interface port; a second redundancy module having: two WAN ports connectable with the WAN, and a second interface port; and a first interworking module connecting the first with the second redundancy module via the first and the second interface port, and adapted to forward protection data between the first and the second redundancy module.

Abstract: An exemplary method and system of the present disclosure use the Parallel Redundancy Protocol PRP (IEC 62439-3) for traffic duplication and redundant transport of the duplicated traffic in a single packet-switched wide-area communication network including a plurality of nodes interconnected via inter-node links in a meshed topology. The method involves identifying, between a send and receive node, two distinct communication paths with no link or node in common except for the send and receive node, and configuring the send and receive nodes to operate according to the Parallel Redundancy Protocol PRP. At any time during regular operation, and for any critical message to be transmitted from the send to the receive node, two redundant packets can be generated, and each of the redundant packets is sent via one of the two communication paths, resulting in an increased availability of the communication network without incurring the cost of full network duplication.

Abstract translation: 本公开的示例性方法和系统使用并行冗余协议PRP（IEC 62439-3）用于在单个分组交换广域通信网络中的复制业务的业务复制和冗余传输，所述单个分组交换广域通信网络包括经由帧间互连的多个节点 - 网状拓扑中的节点链接。 该方法包括在发送和接收节点之间识别两个不同的通信路径，除了发送和接收节点之外没有共同的链路或节点，并且将发送和接收节点配置为根据并行冗余协议PRP进行操作。 在常规操作期间的任何时间，并且对于从发送到接收节点的任何关键消息，可以生成两个冗余分组，并且每个冗余分组通过两个通信路径中的一个发送，导致增加 通信网络的可用性，而不会导致完全网络重复的成本。
