Abstract

A content server defending system for defending content servers that distribute content registered through the Internet to internet terminals, which are capable of connecting with the Internet, against false access. The system comprises auxiliary servers with which copied content data copied from at least a part of distribution content data registered with the content servers is registered, and which are capable of distributing the copied content data to the internet terminals; an access dispenser for assigning requests from the internet terminals to distribute the content to each of the servers so as to substantially equalize the distribution load on each server; a false access detector for detecting false access to each server; and a false access cutoff for cutting off the communication of false access when the false access detector detects the false access.

Claims

1. A content server defending system for defending content servers that distribute content registered through the Internet to internet terminals, which are capable of connecting with the Internet, against false access, said system comprising:

auxiliary servers with which copied content data copied from at least a part of distribution content data registered with said content servers is registered, and which are capable of distributing the copied content data to said internet terminals;

an access dispenser for assigning requests from said internet terminals to distribute the content to each of said servers so as to substantially equalize the distribution load on each server;

a false access detector for detecting false access to each server; and

a false access cutoff for cutting off the communication of false access when the false access detector detects the false access.

2. The content server defending system according to claim 1, wherein a false access detector and a false access cutoff are provided corresponding to each server, the false access detector or the false access cutoff of each server notifies another false access detector or false access cutoff of information regarding the false access based on the detection of false access by said false access detector.

3. The content server defending system according to claim 1, wherein said access dispenser combines a DNS server that transforms a domain name on the Internet into an IF address of each server on the Internet.

4. The content server defending system according to claim 1, wherein domain names, which are released to the public and different from those of the content servers, are given to said auxiliary servers, and the IP addresses of the content servers are not released to the public.
