Active Names: Flexible Location and Transport of Wide-Area Resources
Amin Vahdat, Duke University; Michael Dahlin, University of Texas at Austin; Thomas Anderson, and Amit Aggarwal, University of Washington
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 performance measurements,
location-independent data transformation, 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 Active Name programs are mapped onto available wide-area
resources to optimize performance and availability.
