Embodiment Construction

[0025] Functional Overview

[0026] Considering that the virtual interface technology is used to realize the data communication between the NCP board and the optical board in related technologies, the forwarding efficiency of the virtual interface is low, it is difficult to upgrade the CPU chip of the optical board, and the problem of high cost when using Ethernet technology to realize data communication , the embodiment of the present invention provides an improved data transmission scheme. The network element control board determines the optical port number according to the preset mapping relationship between the destination IP address and the optical port number, and sends the data and the optical port number to the optical board, and the optical board then transmits the above The data is distributed to at least one optical port corresponding to the above optical port number. In the embodiment of the present invention, the processing of the above-mentioned mapping relations...

Abstract

The present invention discloses a data transmission method and a system. In the method, a network element control single board confirms the number of at least one optical interface corresponding with the target IP address of data; transmitting the data of the network element control single board and the number of at least confirmed optical interface to a multi-optical-interface single board; receiving the number of at least one optical interface and the data by the multi-optical-interface, and transmitting the data to at least one optical interface corresponding with the number of at least one optical interface. According to the technical solution provided by the invention, the reliably transmission of the data can be realized and the updating difficulty is reduced. Furthermore the cost can be reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and system. Background technique [0002] In a network element of large-scale transmission equipment, an optical interface single board (multi-optical port single board, referred to as an optical board for short) has multiple optical ports, for example, the number of optical ports has reached 32 at present. In the future, the number of optical ports may be more, and the supported capacity may be larger. Since the way of communication between the NodeB Control Processor (NCP) board and the above-mentioned optical port determines the transmission quality of control signaling and network management information, the communication between the NCP and the optical board will be an optical transmission The core technology of equipment network management. [0003] At present, there are many methods to realize the data communication between the NCP board and ...
