The Local Traditional SDH Optical Network Intelligentize

Along with the development of economy, besides the tradition voice continue to grow sustained, ADSL, the IP broadband business and the VIP customer special line service is also keep fast develop. The growth of bussiness require to the network have a higher demand. Facing this kind of change, the short of the capacity, coating ability and multi-handling of traffic ability, and when original ring network carries on the massive node,it is will face the low use efficiency, protects questions and so on. In addition, looking from the long-term development, the transmission network also needs to have a better elasticity and the flexibility, in order to provide a higher network security, the more nimble service dispatch and the more perfect variation service ability.With the development of the local network business, how to enhance the network security and the broadband width use factor to become more and more important. The ASON is the new generation optical transmission network which can intellectualize completes the optical network exchange connection, it is change from providing the purely foundation network connection in the past to provides many kinds of intelligent services, it is represented the next generation optical network development direction. Along with many kinds of service's development, the local transmission network is more urgent request to the intelligence, and the optical transmission network which is base on the ASON technology can adapt this development demand very well.
