The Construction Scheme's Design And Implementation Of Dezhou Unicom's Metropolitan Area Network

With the continuous development of information era, multiple network levels of business application layer are emerging one after another, voice, video and data information into explosive growth, such as the business network transmits to communication network is more and more big, the particles is very pressing bandwidth requirements. But domestic operators existing metropolitan construction time earlier, simple structure, network widespread business functions of a single, network protection ability is poor. Therefore, to network optimization of metropolitan area is imminent.This paper briefly analyzes the Texas unicom intracity networks on the current situation and existing problems, according to the current business operators of telecommunication level features for the existing problems of Texas unicom metropolitan new network technology, application, combine specific equipment selection, this paper puts forward a metropolitan optimization solution. In order to alleviate technology restriction, because the metropolitan resource exhaustion, and cause operation pressure, and for other network man relay business provides perfect protection, reduce the network operating risks, all kinds of business for Texas safe operation of the local provide cogent safeguard, puts forward the Texas metro wavelet network construction plan. Using WDM technology and appropriate redundantconfiguration, Texas metro wavelength for local broadband IP network can man, ip-based softswitch bearing network business network provides ample transmission capacity. Considering the possibility of late, existing network expansion can fully do with diffuser, with no break with other operating business expansion, to realize smooth.Based on modified through the optimized performance evaluation, Texas metropolitan that Texas after improvement new unicom intracity networks will become a can offer high speed, high bandwidth, high stability, manageable and can provide different service ability of bearing network, how business can satisfy various business development in the metro needs.
