Abstract
Distributed computing continues to be an alphabet-soup of services and protocols for managing computation and storage. To live in this environment, applications require middleware that can transparently adapt standard interfaces to new distributed systems; such software is known as an interposition agent. In this paper, we present several lessons learned about interposition agents via a progressive study of design possibilities. Although performance is an important concern, we pay special attention to less tangible issues such as portability, reliability, and compatibility. We begin with a comparison of seven methods of interposition, focusing on one method, the debugger trap, that requires special techniques to achieve acceptable performance on popular operating systems. Using this method, we implement a complete
