Problems solved by technology

[0006] In the process of realizing the present invention, the inventor found that due to the introduction of ASON, the control information and management information that need to be transmitted through the DCN are increasing day by day, and the small communication bandwidth of the DCC has been difficult to meet the communication bandwidth requirements for information transmission through the existing DCN. Requirements; and some devices in the existing network may not support D-byte transparent transmission, and the risk of communication between devices is relatively high

Embodiment 1

[0056] An implementation method of information transfer, see figure 2 , the implementation method of the above information transmission may include:

[0057] 210. The first node establishes an Ethernet point-to-point protocol session with the second node, and obtains the identification of the above-mentioned Ethernet point-to-point protocol session and the corresponding relationship between the optical port of the first node and the above-mentioned Ethernet point-to-point protocol session;

[0058] Specifically, the first node and the second node can use their respective actual MAC (Media Access Control, Media Access Control) addresses, or use their simulated logical MAC addresses to negotiate, and establish a communication between the first node and the second node. Ethernet Point-to-Point Protocol sessions.

[0059] During the process of establishing an Ethernet point-to-point protocol session with the second node, the first node can obtain the corresponding relationship b...

Embodiment 2

[0072] An implementation method of information transmission. For ease of understanding, this example takes each transmission network node including at least three modules of SCC, ETH data module, and SDH line module as an example to specifically illustrate the implementation process of information transmission between transmission network nodes.

[0073] First, see image 3 , image 3 It is a schematic diagram of a transport network in Embodiment 2 of the present invention, as shown in image 3 The transport network shown includes: node A, node B, and node C.

[0074] Wherein, node A includes: system control card 110, ETH data module 120, optical port (1, 1), optical port (2, 1), optical port (3, 1), optical port (4, 1). Wherein, the optical port (1, 1) indicates that the board position number of the SDH line module to which the optical port belongs is No. 1, the port number of the optical port on the SDH line module is No. 1, and so on.

[0075] Node B includes: system con...

Embodiment 3

[0142] A system control module, see Figure 4 , is a schematic structural diagram of a system control module in Embodiment 3 of the present invention. The system control module in this embodiment may include:

[0143] The session establishment unit 410 is configured to establish an Ethernet point-to-point protocol session and obtain an identifier of the Ethernet point-to-point protocol session, and the Ethernet point-to-point protocol session is established between the second node and the first node where the system control module is located.

[0144] Specifically, the session establishing unit 410 may use the MAC address to initiate session negotiation with the second node, and then establish an Ethernet point-to-point protocol session between the first node and the second node, form a PPP link, and obtain the second node information such as the MAC address of the user and the identification of the above session.

[0145] The Internet protocol unit 420 is configured to encap...

Abstract

The embodiment of the invention discloses an information transmission implementation method, a module and a transmission network node. In the technical scheme of the embodiment of the invention, control information and / or management information to be transmitted are / is packaged into Ethernet service, and an Ethernet point-to-point protocol session is established between the transmission network nodes in order to simulate an Ethernet point-to-point link; based on the simulated Ethernet point-to-point link, the control information and / or the management information are / is transmitted between the nodes, consequently, the requirement of the transmission of the control information and / or the management information on bandwidth is met, meanwhile, the risk of communication interconnection between devices is reduced as well, and the requirement on reliability is met.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission implementation method, module and transmission network node Background technique [0002] The DCN (Data Communication Network) in the transport network is mainly used to transmit the control information and management information of the nodes, for example, the alarm management information, performance monitoring information and network configuration data of the transport network nodes are all transmitted through DCN for transmission. [0003] With the introduction of ASON (Automatic Switched Optical Network, Automatic Optical Switching Network) in the transport network, DCN also needs to be used to transmit GMPLS (Generalized Multi-Protocol Label Switching, General Multi-Protocol Label Switching) control signaling information and so on. ASON puts forward higher requirements on the reliability and communication bandwidth of DCN, requirin...
