摘要： A method for managing a customer edge device 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. 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.

摘要： A packet loss detecting method includes: a first router counts received packets and sent packets respectively according to a class of service value of a packet in each tunnel; the first router generates a first packet loss detection packet corresponding to the class of service value, sends the first packet loss detection packet to a second router at a peer end, and receives a first packet loss response packet returned by the second router; and the first router corresponds a class of service value, and measures 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, packet disorder does not occur when packet loss measurement is performed for a pseudo-wire with multiple classes of service. In addition, traffic detection occupies a smaller bandwidth.
