Abstract: Provided are a method and device for configuring and managing network element equipment, and network element equipment. The method includes that: a management IP address is generated according to network element parameter information; an IGP is started, and a network management VRF and at least one P2P type port is created; the management IP address of an adjacent network element and an a MAC address of the adjacent network element are learned; and network element equipment configuration and management information issued by a network management system is received.

Abstract: Disclosed are a cross-domain protection interacting method and system. The method includes: an interconnecting node on a cross-domain working path between a first domain and a second domain sends second identification information of the second domain to a first node in the first domain, wherein the first domain and the second domain are neighboring domains; when a link failure occurs in the first domain, an interconnecting backup node between the first domain and the second domain receives first failure state information sent by the first node, wherein the first failure state information carrying the second identification information; and the interconnecting backup node activates a second protection path in the second domain according to the second identification information, and uses a first protection path in the first domain and the second protection path to transmit a cross-domain service.

Abstract: Provided are a method and device for configuring and managing network element equipment, and network element equipment. The method includes that: a management Internet Protocol (IP) address is generated according to network element parameter information; an Interior Gateway Protocol (IGP) is started, and a network management Virtual Routing Forwarding (VRF) and at least one Peer to Peer (P2P) type port is created; the management IP address of an adjacent network element and a Medium Access Control (MAC) address of the adjacent network element are learned; and network element equipment configuration and management information issued by a network management system is received.

Abstract: A method for transferring data includes: at the transmit end of data frames, assembling the data frames with a same forward-path into a multiframe as sub-frames; identifying the relevant information of the sub-frames in the header of the multiframe; and encapsulating the multiframe as the payload in the format of frames for transmission in the transport network. An apparatus for transferring data includes: a decapsulation unit, adapted to decapsulate the frames received from the transport network to obtain the multiframe; a multiframe resolving unit, adapted to resolve multiple sub-frames according to the relevant information of the sub-frames that is identified in the header of the multiframe; and a forwarding unit, adapted to send the sub-frames to a customer network according to the forward-paths of the sub-frames.
