Optimization Design And Implementation Of DNS Network

With the rapid development of network communication technology andelectronic commerce, network and data transmission business become one of the corebusinesses of telecom operators. The number of network users surges, makes thenumber of domain name and site increase quickly, and the number of domain nameserver sharp increase. The stability, the reliability and the speed of the Internet hasbecome the most important experience of Internet users. Provide stable and reliablenetwork connection and optimize the speed of surfing the Internet can keep existingcustomers and attract new customers to use mobile network. Among them, improvingthe quality of network service and optimizing the network connection speed is aneffective way. The DNS application acceleration has become the chief problem ofimproving the network quality of service and improving the user access speed.Hardware facilities and software technology are the mainly two ways to solve theproblem how to speed up the DNS network. Hardware facilities mainly increase thenumber of DNS server and use higher performance server, etc. Although theascension of hardware performance is the basic way to solve the DNS network speed,but the hardware update will increase the cost of investment, and is likely to fall intothe predicament of the constantly updated of the high-performance equipment. Fromthe consideration on the overall performance of network, the software technology is akind of project to hoist system effective utilization, mainly including cachingtechnology and agent software technology, etc. However, due to the deficiency of thedesign of the software technology, both caching technology and agent softwaretechnology, can not make very good use of the existing network to transmit the DNSprotocol.This paper is based on the effectively monitoring of the IP address out of theDNS and the mechanism of end user cache technology, and makes full use of thesupport from the Web Service technology, Socket communication and HTTP network transmission protocol. Through the analysis of the performance parameters of theusers visit the web site which is detected by the probe server choose the domain nameIP which has the best performance and the optimal quality to update the DNS cacheserver. Combined with the data of DNS servers at the same time, it provides efficientDNS service, allows access to the user to access the server and obtain the packet attop speed. After experiments and testing, this scheme on the basis of the original DNSserver, further improve the user’s access speed, satisfy the experience that usersquickly surf the Internet.
