METHOD FOR BIT ERROR RATE DETECTION, AND NETWORK DEVICE

摘要

This application provides a method for bit error rate detection, and a device. The method includes: sending, by a first device, a first notification packet to a second device, where the first notification packet is used to instruct the second device to perform bit error rate detection, the first device is an ingress node of a first LSP, and the second device is a downstream node; and receiving, a second notification packet, where the second notification packet carries a second bit error rate, the second bit error rate includes a first bit error rate of a first interface of the second device, and the first interface is an interface that receives an MPLS packet sent by the first device. By using the technical solutions of the present disclosure, the first device can perceive a bit error rate of the second device, thereby helping ensure reliability of MPLS packet transmission.

1. A method for bit error rate detection, wherein the method comprises:
sending, by a first network device, a first notification packet to a second network device, wherein the first notification packet is used to instruct the second network device to perform the bit error rate detection, the first network device is an ingress node of a first label switched path (LSP), and the second network device is a downstream node, on the first LSP, of the first network device; and receiving, by the first network device, a second notification packet sent by the second network device, wherein the second notification packet is used to respond to the first notification packet, the second notification packet carries a second bit error rate, the second bit error rate is obtained based on a first bit error rate of a first interface, the first interface is an interface used by the second network device to receive the first notification packet, and receives a Multiple protocol Label Switching (MPLS) packet that is sent by the first network device through the first LSP.
