Abstract

In order for designers and implementors to evaluate interoperability, trade-offs, performance of algorithms and protocols within distributed applications, experimentation is often necessary. Results obtained from experiments can be ultimately used to improve on the performance, efficiency and reliability of the applications during their operations. In this paper, we consider a general architecture for a distributed applications testbed. We report on the design and implementation of a specific distributed applications testbed for the experimental study of problems related to X.500 distributed directories. Our design and experiences can be useful in the development of similar testbeds for other distributed applications.
