Abstract

Disclosed is a system and method for implementing a distributed network system, such as the World Wide Web, in which distributed location services are utilized and include a collection of server processes that map from resource identifiers to a resource'"'"'s controlling server. In addition, distributed location services provide an architecture for assigning resource identifiers and set of protocols for accessing server processes. The server processes are logically defined to provide a more flexible system. Each of these logical server processes are an abstraction which provides the external view of the server. The logical server processes may be implemented by different numbers of physical processes running on different machines at different points in time.

Claims

1. A program product, said program product comprising:

a recordable media; and

a distributed location service process recorded on said recordable media, said distributed location service process for managing and locating resources in a network made up of clients and servers, said distributed location service process including;

a first mechanism for creating distributed server processes for tracking resources;

a second mechanism for creating and assigning resource identifiers; and

a third mechanism for updating said distributed server processes when resources migrate.

2. The program product of claim 1 wherein said distributed location service process further includes a fourth mechanism for locating resources.

3. A program product for locating resources on an internet, said program product comprising:

a recordable media; and

a distributed location system recorded on said recordable media, said distributed location system including a mechanism for creating a logical location server process for a server on said internet, a mechanism for assigning a resource identifier to a resource on the internet, and a mechanism for updating said logical location server process as resources migrate.

4. The program product of claim 3 further comprising a mechanism for locating resources.

5. The program product of claim 3 further wherein said internet is a world wide web.

6. The program product of claim 5 wherein said resources are web pages.

7. The program product of claim 3 wherein said mechanism for locating resources is accessed by web browser.
