The Design And The Realization Of 3G Transmition Network Based On MSTP And ASON

With the developing of data and 3G serving, the technology of transport network is specially concerned, especially the 3G transport network based on the MSTP and ASON is becoming the direction of telecommunication.The design and realization of 3G transport network based on MSTP and ASON is researched in this dissertation, and a resolve solution is proposed via comparing and summarizing the domestic and overseas actuality of advanced technology such as SDH,MSTP,ASON etc, furthermore, the example and the simulation result were analyzed in the end . In the process of optimization,alteration, and construction, simultaneous transportation of traditional audio service and rising data service was realized in the 3G transport network. It makes the compatibility of the two networks come true, so that the cost of service provider's investment was debased, and benefit the users directly.Presently, the 3G operator is constructing the transport network actively, for the traditional SDH ring network couldn't suffice the service requirement. Produce a perfect 3G transport network with less investment and faster requited, dispose the different layers of the transport network, configure the capacity of transport network according to the service requirement, analyze advantages and the characters of the MESH network, All of these can get the answers in this dissertation which is the concerned topics in this field. The core layer with 5 nodes is the most typical system structure, and this dissertation provides the clarified ideas which can make reference to the practice. Moreover, the dissertation shows some problems need to be paid attention to, for example, the ASON equipment imported should be planed step by step, and the protected and resumed modes should be used deftly in practice. All of them can't be neglected in the construction of 3G transport network.
