Research On The Technologies Of Internet Traffic Localiztion

Since China officially connected to the Internet over a decade, Internet and it’s applicationshas gradually affecting all aspects of people’s life and work. Domestic Internet service is almostthe same as the international.However,due to national policy and other reasons, so that themajority of ISP ’s operating costs are too high, and network performance is poor.Networkoptimization techniques in this article can improve user perception, reduce operating costs andincrease revenues, so that the competitiveness and profitability of the network is improved.Oursuccessful projects test proves that most users have get a good feeling in useing the Internetservice.So the study in this article plays a very important role in ISP networkoptimization.Following works have been finished in this paper:(1) The factors that influenced subscriber QOE (Quality of Experience)and high operatingcosts were analysed.(2) Integrated network management system construction method were discussed. Networktopology were optimized based on integrated network management system.(3) User’s online behavior were analyzed by DPI device.Important nework flow wereprotected and redirected by DPI result analysis.(4) Intelligent DNS,fast DNS response and optimum destination IP address will lead to lightnetwork traffic and better QoE.(5) User network traffic were reasonably redirectd by New DPI devices and intelligent DNSsystem. CACHE and NDC system brought more popular resource into the network whichwould provide better feeling of web surfing.
