摘要： A method, a device and a system for interconnecting a multi-protocol label switching (MPLS) network and an Ethernet are provided. A packet sent by a node located at the Ethernet is received, the packet is parsed, the parsed packet is re-encapsulated by means of MPLS, and the re-encapsulated packet is sent to a node located at the MPLS network, so as to implement interconnection between the MPLS network and the Ethernet. A reverse solution is similar to this. An intermediate node in the solution adopts a manner of parsing a packet and then re-encapsulating the packet when the packet is sent from one network to another network, instead of transparent transmission only. Therefore, it is unnecessary to configure a Media Access Control (MAC) address of a remote node on a node located at the Ethernet and to configure Ethernet information on a node located at the MPLS network.

摘要： A communications network comprises a first node and a second node. The communications network further comprises an unpaired switched-path between the first and second nodes. Connectivity of the unpaired switched-path is tested by the first node transmitting a probe message along the unpaired switched-path and waiting to receive a probe message response as connectionless traffic from the second node. Also disclosed is a communications network component comprising logic that selectively verifies connectivity of a unidirectional communication path based on a probe message transmitted as connection-oriented traffic along the unidirectional communication path and a time limit in which to receive a probe message response as connectionless traffic. Also disclosed is a communications network component comprising at least one processor configured to implement a method. The method comprises selectively transmitting a probe message along a unidirectional connection-oriented path and waiting to receive a virtual local area network (VLAN)-based probe message response.

摘要： 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 MAC address and VLAN ID of identifier of a path where a monitored service is located, and thus may be forwarded correctly in a PBB-TE network.
