<p>A packet loss detecting method and apparatus, and a router are provided in embodiments of the present invention. The method includes: counting, by a first router, received packets and sent packets respectively according to a class of service value of a packet in each tunnel; generating, by the first router, a first packet loss detection packet that is corresponding to the class of service value, sending the first packet loss detection packet to a second router at a peer end, and receiving a first packet loss response packet returned by the second router; and corresponding, by the first router, a class of service value, and measuring a packet loss value according to a locally recorded count value and a count value carried in the first packet loss response packet. With the technical solution in each embodiment of the present invention, a problem that packet disorder occurs when packet loss measurement is performed for a pseudo-wire with multiple classes of service, causing that a packet loss measurement result is not accurate is solved. In addition, an advantage that traffic detection occupies a smaller bandwidth also exists.</p> |
