Network distribution device and method based on SDN architecture

Abstract

The invention discloses a network distribution device and method based on SDN architecture. The device includes a receiving module used for receiving and analyzing request information of a user terminal and resolving the request information for obtaining a source IP address; an inquiring module used for inquiring preset line information configuration table according to the source IP address, obtaining the communication operator information, inquiring a preset communication operator DNS information configuration table according to the communication operator information and obtaining the corresponding DNS server information; a sort module used for setting a webpage high frequency access threshold value and dividing user terminal request content into hot content and non-hot content according to the threshold value, and storing the hot content to a local storage device from a WEB server; and a transmission module used for transmitting the request content of the user terminal to the user terminal from the WEB server or the local storage device. According to the invention, network distribution can be performed according to the operator of the user terminal, so that equipment pressure of the network operator can be reduced, a user can access network smoothly and good user experience can be achieved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a network distribution device and method based on an SDN architecture. Background technique [0002] With the development of Internet technology, the number of Internet users has also increased sharply, and the ways Internet users access the Internet have also become more abundant. The large number of Internet connections has greatly tested the performance of network providers' equipment. There is a one-to-one correspondence between domain names and IP addresses on the Internet. Although domain names are easy for people to remember, machines can only recognize each other’s IP addresses. The conversion work between them is called domain name resolution. Domain name resolution requires a dedicated domain name DNS is the system for domain name resolution. [0003] The traditional domain name system is a distributed database that maps domain names and IP addresses to each other...

AI Technical Summary

Problems solved by technology

When a large number of users access the Internet, the domain name resolution service must be congested, the domain name resolution DNS server and WEB server must be overloaded, and user terminals cannot smoothly access the network, resulting in poor user experience.
