| The present communication service set the high request to the correspondence network, the network optimization, the route, the protection and the self-recovery function in the optical communication domain the more and more heavy instant.The intelligent exchange light network can guarantee the network the reliability and provides the nimble signal route platform, although the existing communications system all uses the electric circuit exchange technology, but develops the intelligent light network to need to complete the signal route function actually by the intelligent exchange technology to realize the network high speed and the agreement transparency. The intelligent light exchange technology for enters the node the high speed information flow to provide dynamic light territory processing, will only belong to this node and about the subnet information Lu Bing hands over by the electricity commutation equipment continues to process, like this will have following several merits:1, overcomes the pure electronic exchange the capacity bottleneck question; 2, saves the fishing net and the network promotion cost massively;3, enhances the network greatly the restructuring flexibility and the survivability,4, speeds up the time which the network restores.In the intelligent light network system, the light exchange node equipment is its important core equipment, but the intellectualized distributional control software platform is in the intelligent light network system important composition technology.Certainly composes the intelligent light network is not merely the core commutation equipment and the intellectualized distributional control software platform, it also includes the network to transmit the platform and the network management platform. Core commutation equipment in under the standard signaling control, according to the different user demand, the route algorithm (for example OSPF) and the transport protocols (for example OSRP), dynamic establishes the end-to-end path of rays for the user; The intellectualized distributional control software platform the control function module will insert to various nets Yuan in, each net Yuan might real-time, dynamic exchange the correlation route and the node information, thus will make each net Yuan Kecong in the dynamic route agreement to understand the entire network topology and the correlation link condition; Transmits the platform is uses as the intelligent exchange light network basic physical transmission carrier.The intelligent exchange light network through a net Yuan intellectualization, changes the central management is the distributional management, releases original network management many functions to various nets Yuan in, thus has realized the network real-time manipuility.Causes the work which many needs to participation artificially originally to cause network itself to complete, this enormously strengthened the entire network service efficiency.Nimble, the fast service provides is one of intelligent exchange light network important functions. Moreover, the intelligent light network causes the light network"the pipeline network"to approach"the service network"from the tradition the evolution.This kind of evolution was not to before constructed the network the abandonment, but was a seamless fusion innovation process, has protected the user original investment to a great extent.Through the intelligent exchange light network, the correspondence service provider may according to the actual need, facilitate freely carries on the effective management and the use to the network band width resources.This article in analysis network service after light network development impetus as well as intelligent light network starting, emphatically described some company intelligence light network construction as well as this network overall performance and the existing transmission network superiority, finally briefed the intelligent light network trend of development and to the market the influence. |
