Abstract: A system and method for selecting an optimal authoritative name server includes global authoritative name servers and regional authoritative name servers. The local name server receives a request for target objects from a client. The local name server inquires one of the global authoritative name servers about an IP address of a requested domain. The selected global authoritative name server initially responds to the local name server. For subsequent requests, the selected global authoritative name server guides the local name server to inquire one of the regional authoritative name servers by providing a new authoritative name server list including a group of regional authoritative name servers designated to serve a network location of the local name server. The system and method for selecting the optimal authoritative name server may have practical applications in a content delivery network system.

Abstract: A host migration system having an first server, a second server and a relay server is provided. The first server is currently hosting an internet service having a predetermined domain name. The first server has a first IP address. The second server has a second IP address and the relay server has a third IP address. The first data packet of a request from users is redirected to the first server from the third server and a second data packet of the request is redirected to the second server from the third server. The data packet redirection may occur as an IP address mapped to the domain name is changed from the first IP address to the second IP address via the third IP address. The host migration system may provide substantially minimized downtime and data loss and corruption may be prevented.

Abstract: A system and method for controlling internet traffic controls internet traffic directed to a non-existing domain in a centralized manner. Instead of a non-existing domain response, the user may receive alternative responses such as a landing page including useful information and resourceful suggestions under the control of a global controller. The centralized control over the user's request may be implemented by redirecting a DNS query to the global controller or an optimal search guide server at an individual internet service provider level. Redirection of the DNS query may involve a record modification of a domain name resolution response indicating the non-existing domain.

Abstract: In a multi-level redirection method, a first level redirection of a first request is performed based on static information. At a manager, a second level redirection of a second request is performed to an agent server based on dynamic information. The manager is configured to monitor an individual status of the agent server. The static information is associated with selection of the manager and the dynamic information is associated with selection of the agent server. The second level redirection is application redirection performed based on application protocols and contents used in the first and second request.

Abstract: A hosting platform includes a main server layer and an auxiliary server layer. The main server layer includes one or more servers and a server of the one or more servers is designated to process requests for one or more hosts. The auxiliary server layer may be removably coupled to and in communication with the main layer. The auxiliary layer may process the request redirected from the main layer when the designated server of the main layer is overloaded.
