The Appraisal And Analysis Of Implementing Scheme Of The Net Switch And NGN

This subject stems from China Telecom's prove project of NGN construction.In a situation that present information technology and industry are developed at full speed, IP network, 3G and ALL-OPTICAL NETWORK of new generation have already begun to implement. Various kinds of information networks must be merged. At the same time, the telecommunication operation business must be merged in NGN network transmitting such business of the multimedia as the data, pronunciation and picture, etc. In order to account for the first chance in the new revolutionary tide of telecommunication circle, each world scientific and technological big country regards exchanging its key technology softly as to develop. They have already made and responded the international standard and offered to developer widely the platform. The bandwidth of the network is NGN's key technical indicator. In a situation that ALL-OPTICAL NETWORK are ripe day by day, all optical IP networks become key networks of NGN. And assessing NGN characteristic and index for measurement, corresponding information flow must keep developing with the construction of NGN network in step in theory while lining up. With the gradual construction and operation of NGN network of our country, it is the great technological subject in front of us how to carry on analysis and appraisal to various kinds of performance indexes in the course of implementing NGN network. Evaluation system can't already meet growing telecommunication network's needs in network analysis of already existing telecommunication of our country. And appraise the adoption which analyses the platform, will improve it and appraise competence greatly in new network performance, thus promote the development of the telecommunication industry of our country. The groundwork of this thesis is to expound the fact how to implement NGNnetwork. The realistic meaning of NGN network system has been described at first ,and it has discussed the concrete method to realize, analyzed NGN relation about standard room in detail . Some questions that should be paid attention to in the network design of NGN have been pointed out Then according to the demand for the system .The relation among NGN bandwidth and ALL-OPTICAL NETWORK is discussed. The existing and under construction NGN characteristic, operation characteristic of network existing and prospect are analysed with international, domestic various kinds of final and previous theory and technology to prepare in NGN construction for our country are offered.
