Abstract

A generic address resolution system facilitates communications among multiple network applications with heterogeneous addressing mechanisms, thereby allowing the network applications to interoperate with each other and/or with modules for providing enhanced functionalities. The address resolution system includes a resource mapping module that modularizes the components needed for address resolution and abstracts content from the underlying address types and content used by the network applications. The address resolution system includes a context engine that analyzes the addressing data to be resolved, selects one or more appropriate destination network applications based on contextual rules, and creates the application mapping template for the end-end routing of the communications among the network applications.
