Automatic Switched Optical Network Technology And Application

With the domestic telecommunications industry has entered a new stage of development, optical network technology from the previous blind pursuit of super-capacity optical network mode, gradually changing to a more cost-effective building a new generation of optical networking onto. Automatic Switched Optical Network to present to the entire telecommunications network planning and design, architecture and operations will have far-reaching implications.This paper first analysis of the traditional shortcomings of the optical network, and automatically switched optical network characteristics; Next, expounded ASON (Automatic Switched Optical Network) architecture, network architecture model and the standardized process.The ASON, business can achieve dynamic link slot resources can be dynamically allocated, and its tenet of the existing network-layer control plane, and to use this layer control plane to establish a link to the user, providing services and the underlying network control, and support different technical programs and different business demand, high reliability, scalability, and high efficiency characteristics. The operators have intelligent optical networking, network deployment has become more flexible and can be the voice signal transmission, Internet IP transmission, ATM signal transmission, FRAME RELAY transmission, and digital image signal transmission integration, which can transmit the same signal platform to provide voice, data signals, image signal transmission, to achieve the reunification of transmission networks, transmission service providers in the lower investment business in providing transmission services, and strengthen transmission services to business competitiveness and operational upgrades easy network maintenance and management costs down, and can provide a variety of types of network Tongxinluo recovery mechanisms.Major domestic operators are actively tracking study, the plan pilot network projects, the United States telecom operators Touch famous American and Australian carriers, such as Optus has also started for the intelligent optical network deployment. Through the use of Huawei equipment, Liaoning Telecom Jinzhou local network MESH Network Planning and Design, and finally to put practical application, a summary of the results.
