A service mediation framework may allow each component within a computer network to perform common service processing tasks driven by standardized service policies stored within a centralized repository. In particular, an enhanced service domain name system (DNS) server, an enhanced service router, and/or an enhanced service gateway within the network may each access relevant service policies stored within an enhanced service repository to implement tasks such as security, content-based routing, logging, message format translation, and protocol bridging for each service request processed by the network. In addition, each network component may communicate through standardized formats, such as Extensible Markup Language (XML), to realize the end-to-end network solution.
