In this paper, we explore flexible name resolution as a way of supporting extensibility for wide-area distributed services. Our approach, called Active Names, maps names to a chain of mobile programs that can customize how a service is located and how its results are transformed and transported back to the client. To illustrate the properties of our system, we implemented prototypes of server selection based on end-to-end performancemeasurements, location-independent data trans-formation,and caching of composable active objects and demonstrate up to a five-fold performance improvement to end users relative to protocols in widespread use.We show how these new services are developed, composed, and secured in our framework.Finally, we develop a set of algorithms to control how mobile ActiveName programs are mapped onto available wide-area resources to optimize performance and availability.
