Abstract:

In a parallel retrieval method for a web request to a particular web host from a client, a request for a target object is redirected to a best agent. The request for the target object is sent according to a designated domain name for agents instead of a domain name of the particular web host. The target object includes a first object and a second object. At the best agent, the request for the first object is associated with a domain name of a first server and the request for the second object is associated with a domain name of a second server. The request for the first object is sent to the first server and the request for the second object is sent to the second server. The client obtains in parallel, the first object from the first server and the second object from the second server.

US Classification:

709238, 707100, 707E17044

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 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.
