Research And Design Of DNS Control Accuracy System On Operation Business Of Optimization Flow Control

After all operators in the whole business,increasingly intense competition,there have been many competing approaches.But it's mostly about lowering fees and improving the quality of existing networks to capture market quotas,keep existing markets.In the long term,reducing the cost of capital has only a temporary effect.It can be used as an incentive,however,long-term development should be a powerful means to enhance customer perception and ensure network quality.Today,all kinds of network application and service of VOD demand high quality of network such as low latency.When user access network contents,Internet Content Provider deploy amount of CDN server on operation business network,for the purpose of improving on accessing speed and service quality of Internet.It can ensure that users could access self-possessed content which is internal network of operation business.DNS Control Accuracy System aim at optimization flow control system which is based on China mobile tietong company Internet DNS guidance optimization guideline.In this thesis,it combines with the status of the China Tietong Gansu Branch flow management.The paper proposes to build a system which based on a perfect and secure DNS system that could analyze traffic for the purpose of increasing percentage of free traffic as well as saving the charge of output bandwidth.The DNS control Accuracy system could promoto user's perception and support Operation of traffic management.Against background of building DNS control accuracy system,the paper elaborate the design scheme of DNS's recursive,network resources exploration,data analysis,operation of CDN as well as system security.According to the problems of the high proportion in using the oteher operation business' s DNS,the paper design the optimization scheme of recursive DNS which is based on the principle of DNS resolution,We discuss an implementation of method which could transform user request for the oteher operation business' s DNS into request for the CTT's DNS.So it is able to reduce cost of traffic.According to the problems of the CTT's DNS can't intelligent resolve free resources of CMCC' network,the paper design the solution of detection network resouces which uses K nearest neighbor algorithm and hierarchical clustering principle.We discuss an implementation of method which could share resource between CMCC' network and CTT's network,and promote user's perception.According to the problems of the construction of CDN's content is blindness,the paper design the solution of network behavior analysis which is by the mass data mining technology.The solution will lay a foundation for increasing the rescource congtents of netwrok.By designing and constructing DNS control accuracy system,the following goals have been aimed at achieving: the system can effective control the user's charge traffic of outbound which is sent to the other operation business' s network,and the systetm can permit CTT's user to access CMCC's resource of network and promote user's perception with rational deployment of CDN's resource...
