网络装置内发生信号丢失事件之后的自动恢复
摘要：
本发明公开了网络装置内发生信号丢失事件之后的自动恢复，其中一种交换机装置可确定在连接本地链路伙伴和远程链路伙伴的通信链路上发生信号丢失事件的时间。所述交换机装置可自动进行链路重启处理，以恢复与所述远程链路伙伴的通信，而不与所述远程链路伙伴进行速度协商。所述链路重启处理可包括在恢复期间禁用发送器并且将发送器和接收器配置为初始配置状态。所述链路重启处理也可同步开始所述本地链路伙伴和远程链路伙伴之间的训练协议通信。在从所述远程链路伙伴中接收的通信量未达到链路标准时，所述交换机装置也可执行所述链路重启处理。
摘要（英）：

The invention discloses automatic recovery after loss of signal event in a network device. A switch device can identify when a loss of signal event occurs on a communication link connecting a local link partner and a remote link partner. The switch device may automatically perform a link restart process to restore communication with the remote link partner without performing a speed negotiation with the remote link partner. The link restart process may include disabling a transmitter for a recovery duration and configuring a transmitter and a receiver to an initial configuration state. The link restart process may also synchronize the start of a training protocol communication between the local link partner and remote link partner. The switch device may also perform the link restart process when traffic received from the remote link partner fails a link criteria.
