Method for managing and controlling data transmission based on optical fibre

Abstract

The invention relates to a method for transmitting manage control data, based on optical fiber, which comprises: the near node packs the optical fiber device into independent Ethernet device, to distribute one mac address and an IP address; the remote node packs the optical fiber devices that connecting superior and lower optical fiber devices into one Ethernet device, to only distribute one mac address and one IP address; sending the mac data pack of IP layer; receiving the data of optical fiber. With said invention, there is full-IP connection between near and remote nodes, to use mature TCP / IP protocol, with simple setting of static route and easy automatic program, while part route relation is processed at the IP device driving layer, to reduced the needed resource.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for transmitting management and control data through optical fibers between a near end and a far end in a distributed system. Background technique [0002] In the field of communication, there are a large number of distributed systems. The distributed system is often composed of the proximal node of the distributed system and the remote node of the distributed system. The remote node of the distributed system is connected to the proximal node of the distributed system through an optical fiber. It can be placed several kilometers away from the near-end nodes of the distributed system, which greatly improves the coverage of the near-end nodes of the distributed system. [0003] figure 1 It is a schematic diagram of the connection between the near-end node and the remote node in a typical communication system. The inside of the near-end node and the inside of the remote node are ...

Problems solved by technology

[0005] For the management and control data between the near-end node and the remote node, there are usually two transmission methods. One is to directly use the data part of the HDLC frame on the optical fiber to carry the management and control data. The disadvantage of this method is that There is no longer an all-IP connection between the single board on the far-end node and the single board on the near-end node. For some applications using the TCP / IP protocol, there are difficulties, and it does not conform to the trend of the entire communication system; another way, It carries IP data packets on the data part of the HDLC frame on the optical fiber, and the management control data is carried in the IP data packets. For each optical fiber connecting the remote node and the near-end node or connecting two remote nodes, it is regarded as one A single point-to-point IP device, in this way, the single board on the remote node and the single board of the near-end node are all IP connections, but because the IP packets are carried, there are multi-level remote node cascade connections Finally, the static routing setting is complicated. When the single board of the near-end node communicates with the single board of the remote cascaded remote node, it is processed through multi-level routing, and this processing is performed at the IP layer in the TCP / IP protocol stack. The CPU resource consumption is large, and the overall efficiency is low
