RESOLVING HIERARCHICAL ADDRESSES USING SERVERS LOAD BALANCER

摘要

The present invention provides a system, method, and article of manufacture for resolving a hierarchical address into an IP address. The system includes a first set of plurality of name server processes for resolving the hierarchical address and a second set of plurality of name server processes for resolving the hierarchical address, wherein each of the name server processes in the second set of plurality of name server processes has a corresponding process in the first set of plurality of name server processes. The system also includes a load balancer for receiving a name resolution request that includes the hierarchical address and for sending the request to either one of the first set of plurality of name server processes or to the corresponding process in the second set of plurality of name server processes to resolve the hierarchical address into an IP address.
