Intelligent Optical Network The Routing Wavelength And Signaling Control Technology Simulation Study

Facts have proved that the development of optical network technology has been driven from the main business drivers into the main. In order to adapt to future business data, differentiated, and real-time characteristics and requirements, a variety of intelligent control technology to be introduced into the next-generation optical network in the past. Intelligent optical network control technology is a dynamically, automatically connected to the network transmission network. Dynamic service request initiated by the user, automatic routing, signaling control achieved by the establishment of links, removal, financial exchange and transmission as one of the next-generation networks. Optical networks as the main communication network information society, with the rapid growth of data services, the explosive demand for broadband. Made a whole new generation of optical network control technology development, it must have: to provide fast service; flexible network structure; value-added business platform; reliable network protection; higher resource utilization.The main work of this dissertation is the intelligent optical network routing and wavelength assignment signaling also control the simulation study, the main structure of this paper is divided into six chapters, the first chapter mainly for the main structure of the intelligent optical network and its merits description; second chapter is the intelligent optical network control system for elaboration; chapters 3 and 4 is the intelligent optical control of an important part of the signaling and routing and wavelength control technology for simulation; Chapter simulation software is introduced; sixth full chapter is a summary and future prospects. In this paper, to achieve the following areas:(A) the successful implementation of the intelligent optical network signaling control the simulation. Intelligent node starts, the first neighboring network element and the establishment of control channel to communicate with each other. Each signaling protocol between the entities will select the best channel, reducing the time to establish channel, signaling the time to achieve control. (B) the successful implementation of data link routing and wavelength assignment. Blocked by the algorithm to select the routing path from the new link and wavelength assignment, choose the best path for the communication to improve communication efficiency.(C) demonstrate the above problems and simulation. Data obtained by the simulation study, to improve these factors can prove effective to improve the performance of intelligent optical networks.
