The Design And Practice On Ason Of Jiujiang Unicom

Traditional SDH optical network primarily designed for voice service, and its topology to linear and ring-based, business configuration, the need for each aspect of the business path point by point and time slot allocation, it is difficult to real-time management, changes in network topology can not reflect the real-time network tube. Although the topological structure of these under the protection of the advantages of a fast switching, but its poor network expansion and lower bandwidth utilization (due to the protection ring to the need to reserve half the bandwidth). With the increasing scale of networks, the increasing complexity of network structure, management, maintenance of the pressure increasing, the allocation of high-risk business in a manner; At the same time, Since the business opened from the application to the real, are artificial, and especially when the number of manufacturers involved in the interconnection of equipment, the need to manually coordinate the efficiency is very low, usually takes weeks or even months. It is hoped that with new technologies and achieve dynamic business applications, routing, business automatically, which simplifies network management, reduce operating costs. This came into being intelligent optical network.According to the original Jiujiang Unicom transmission network problems, especially the western10G loop covering5counties, the cable span500kilometers, are laid overhead, appear every year many cable multiple simultaneous disruption caused by paralysis of business area, to the company network security into great influence, at the same time the original Unicom network design main consideration support mobile communication narrowband, capacity is low, and the service form is one of old, cannot effectively carrying data multimedia full business, to the company’s business development has brought adverse effects, in order to solve the problems, we introduce the technology of intelligent optical network, from the performance and function of the original network transformation, has had the ideal effect.This article is divided into five chapters, the first chapter is the introduction part, mainly on the research background, research content and research organization structure are described; the second chapter of the transmission related technical details, including SDH, WDM and ASON; the third chapter of Jiujiang Unicom local transmission network application of ASON technology in concrete design scheme; fourth chapter ASON engineering practice, the third chapter of the design implementation of the deployment, the existing network to renovate the building, to achieve the ASON network operation; the fifth chapter testing and optimization, through the functional and performance testing, validation of the ASON network construction expected. According to the test results and the new ASON network by the problems of Jiujiang local transmission network to improve train of the thought.
