Abstract

A network of point of presence servers allows a customer to organize their web site by functions where functions are mapped into domain names. The functions have requirements that define what is needed by a server to satisfy the function. The domain names are mapped into resources or servers that can be addressed by the domain name and that satisfy requests for the function that domain name has been defined to support. This method of organization allows individual elements of a web page to be retrieved from different resources and gives the name server the control to direct users to an available and optimal server for a given resource.

Claims

1. A method for individual elements of a Web page to be retrieved from different resources:

organizing a Web site by functions where functions are mapped to domain names;

wherein functions have requirements that define what is needed by a server to satisfy the function;

mapping, on a name server, the domain names to servers that can be addressed by a particular domain name and that satisfy requests for a function that the particular domain name has been defined to support; and

directing, by the name server, user requests for functions from the Web site to an available and optimal server for a given function by returning to the requesting user an IP address of the optimal server.

2. A apparatus for individual elements of a Web page to be retrieved from different resources:

a name server;

wherein a Web site is organized by functions where functions are mapped to domain names;

wherein functions have requirements that define what is needed by a server to satisfy the function;

a module, on the name server, for mapping the domain names to servers that can be addressed by a particular domain name and that satisfy requests for a function that the particular domain name has been defined to support; and

a module, on the name server, for directing user requests for functions from the Web site to an available and optimal server for a given function by returning to the requesting user an IP address of the optimal server.
