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.

A method for transmitting a Connectivity Fault Management (CFM) message of Ethernet includes: receiving a CFM message transmitted from a source node, the CFM message including identifier of a path and a connection maintenance target address; determining whether the connection maintenance target address matches address of a receiving node, and if yes, terminating the CFM message; otherwise forwarding the CFM message to a next hop based upon the path identifier of the path. Another method and a system for transmitting a CFM message of Ethernet, a node for transmitting a CFM message of Ethernet, and a node for receiving a CFM message of Ethernet are also disclosed. With the invention, a CFM message may be forwarded according to information of a Medium Access Control (MAC) address and a Virtual Local Area Network Identifier (VLAN ID) of a path identifier where a monitored service is located, and thus may be forwarded correctly in a Provider Backbone Bridge Traffic Engineering (PBB-TE) network.

A method of rate-control for a group of ports in a communication network. Ramping is performed for allowed-rate of each of the group of ports, if sum of the ingress-rates of the group of ports is less than a given rate threshold; and adjusting is performed for allowed-rate of each of the group of ports, if sum of the ingress-rates of the group of ports is greater than or equal to the given rate threshold, such that the sum of allowed-rates of the group of ports is equal to the given rate threshold.

In an Ethernet network divided into multiple domains, a method for Ethernet data frame data learning includes: receiving through a bridge port of a domain of the Ethernet network an Ethernet data frame containing a source Media Access Control (MAC) address; and generating a forwarding matching entry including a destination MAC address, the length of a forwarding mask and a bridge egress-port identifier; wherein the destination MAC address is acquired by matching the source MAC address with the length of the forwarding mask. In a method for Ethernet data frame forwarding, a bridge forwards the Ethernet data frame according to a MAC forwarding matching table including a destination MAC address, the length of a forwarding mask and a bridge egress-port identifier. An Ethernet network and a bridge are also provided. The number of entries included in the MAC forwarding matching table o is reduced effectively.
