INTRUSION TOLERANT TECHNOLOGIES OF DNS AND DHCP SERVER FOR SURVIVAL OF INTERNET SERVICE

摘要

The present invention relates to a DNS / DHCP server intrusion tolerant technology for securing the Internet service survivability. More specifically, in sync with the primary DNS / DHCP server to provide Internet DNS / DHCP service, even if by a secondary DNS / DHCP servers that provide the same DNS / DHCP service, a failure occurs in any one of the servers, the other servers synchronized relates to a DNS / DHCP server intrusion tolerant technology for securing the Internet service survivability that can provide the same services to consistently. ; Furthermore the present invention, the primary DNS / DHCP server and the secondary DNS / DHCP server of the service results in respect boating (voting) to perform to a failure in the server prior to the discovery by, DNS / DHCP service to for reliability ensuring can do. ; DNS, DHCP, intrusion, boating (voting), Internet chaos, firewall (Firewall), policy-based (Policy-based), rules-based (Rule-based)
