Description

Supplying method and supplying system of open ultra-high-speed optical transmission network

The present invention relates to a supplying method and a supplying system of a transmission network, and particularly relates to a supplying method and a supplying system of an open ultra-high-speed optical transmission network.

The traditional optical transport network (Optical Transport Network, OTN) network architecture is usually based on a closed system controlled by the manufacturer's own software, which is planned, managed, and maintained by the manufacturer's own software. Every time a customer selects a certain manufacturer’s OTN, it means that the manufacturer’s own hardware and software must be tested and then integrated into the network. The integration cycle is very long, which greatly reduces the speed of competition and innovation. The goal of the Open Architecture project is to introduce more competition and faster innovation through openness and deconstruction, combined with hardware flexibility and software control, to solve the current shortcomings of traditional OTN systems. The Open architecture uses a deconstruction method to disassemble OTN according to functional modules. Different functional modules can be provided by different manufacturers. The different functional modules provided by each manufacturer provide open interfaces, and the transmission body can define the network (T -SDN) controller for unified scheduling and installation. The core concepts and values of the Open architecture are firstly the open hardware, which supports the NetConf/YANG application interface, deconstructs the network and functions, and realizes multi-vendor interoperability; secondly, software control, which is realized through the intelligence of the T-SDN controller Automatic detection and adjustment of bandwidth, detection and automatic recovery of faults, and perception of optical performance can accurately optimize network performance in real time.

If you do not plan well, you will often not find the same optical wavelength value and optical wavelength width of the OMS route. You must add an OMS route to provide the same The value of the optical wavelength and the width of the optical wavelength cause a waste of resources in the open circuit system.
