Abstract: A system and method provide a communications link having a plurality of lanes, and an in-band, real-time physical layer protocol that keeps all lanes on-line, while failing lanes are removed, for continuous service during fail over operations. Lane status is monitored real-time at the physical layer receiver, where link error rate, per lane error performance, and other channel metrics are known. If a lane failure is established, a single round trip request/acknowledge protocol exchange with the remote port completes the fail over. If a failing lane meets an acceptable performance level, it remains on-line during the round trip exchange, resulting in uninterrupted link service. Lanes may be brought in or out of service to meet reliability, availability, and power consumption goals.

Abstract translation: 系统和方法提供具有多个通道的通信链路，以及带内实时物理层协议，其在故障切换操作期间连续服务，保持所有车道在线，同时消除故障车道。 在物理层接收机处实时监控通道状态，其中链路错误率，每通道错误性能和其他信道度量是已知的。 如果建立通道故障，则与远程端口的单一往返请求/确认协议交换完成故障切换。 如果失败的车道达到可接受的性能水平，则在往返交换期间保持在线，导致不间断的链路服务。 车道可能被带入或不服务，以满足可靠性，可用性和功耗目标。
