摘要： The present invention provides a method for managing a customer edge device automatically and a PE device. The method includes: receiving, by a UNI set in a third-party operator network, an E-LMI packet sent by a VUNI set in a service provider network, where the VUNI is configured to manage a RUNI correlated with an EVC in the third-party operator network; converting, by the UNI, a unicast DMAC address in the E-LMI packet into a multicast DMAC address; and sending, by the UNI, the converted E-LMI packet to a CE device connected with the UNI. In the embodiments of the present invention, the E-LMI packet sent by the VUNI set in a service provider network may penetrate the third-party operator network, so that the management information of the service provider network can be transmitted to the CE device that is connected with the third-party operator network through the UNI, thereby managing the CE device in a cross-domain service automatically.

摘要： 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.
