Man The Introduction Of Ason Strategy Study

Compared with the old optical transmission network, Automatically Switched Optical Network(ASON) is more reliable, flexible and efficient. It can Offer dynamic configuration for network. It improves the efficiency of network and the ability of rapid protection and restoration, and it supports business needs of different levels of service, and it can automatically discover network resources and better meet EP transmission. ASON currently represents the new direction of optical transmission network development; the telecommunications operators will apply ASON on the network on a larger scale in recent years. The author works on the optical communications network planning and designing for many years. According to status of the current optical transmission network, this paper analysis the key to ASON technologies and ASON's applications on the transmission network, gives the current building strategy of ASON, and completes the program design of ASON works for Chong Qing Unicorn's Metropolitan Area Network. This paper will offer better information and guidance for building of ASON.
