Abstract: A computer is connected to redundant network switches by primary and secondary connections, respectively. Test messages are sent across each connection to the attached switches. A break in a connection, or a faulty connection, is detected upon a failed response to one of the test messages. In response to this failure, traffic is routed across the remaining good connection. To facilitate fast protocol rerouting, a test message is sent across the now active connection bound for the switch connected to the failed connection. This message therefore traverses both switches causing each to learn the new routing. Rerouting is therefore accomplished quickly.

Abstract translation: 计算机分别通过主连接和辅助连接连接到冗余网络交换机。 测试消息通过每个连接发送到连接的交换机。 在对其中一个测试消息的响应失败时，会检测到连接中断或连接错误。 为了应对这种故障，流量被路由穿过剩余的良好连接。 为了方便快速协议重新路由，测试消息将通过连接到故障连接的交换机的绑定的现在活动连接发送。 因此，该消息遍及两个交换机，导致每个交换机学习新的路由。 因此，重新路由快速完成。
