物理层的保护和恢复速度很快，但可能需要专用硬件。另一方面，IP虽然不依赖于特定的拓扑结构，但速度很慢。基于MPLS的保护对于在故障的情况下将流量重新路由到预先建立的备份LSP是有效的。故障检测在保护和恢复中起着主导作用。提出了一种利用以太网自动协商机制解决MPLS链路和节点保护问题的方法。该方法在检测基于以太网的网络中的故障方面是有效的，并且可以容易地被采用以低开销来支持MPLS保护。实验结果表明，该算法能够在小于30ms的时间内实现业务恢复。
Protection and restoration at the physical layer is fast, but may require dedicated hardware. On the other hand, IP, although it does not rely on specific topology, is slow. Protection based on MPLS is effective for rerouting traffic to a pre-established backup LSP in the case of failures. Failure detection plays a dominant role in protection and restoration. This research presents an approach for addressing MPLS link and node protection by making use of auto-negotiation for Ethernet. The method is efficient in detecting failures in an Ethernet-based network and can be easily adopted to support MPLS protection with low overhead. The experimental results show that traffic recovery can be achieved in sub-30ms.
