Abstract: Distributed, heterogeneous systems are increasingly common, in IT, critical infra-structure, and military applications. Standards-driven middleware provide a simple, flexible abstraction for constructing these systems. Such systems require the provision of customized, localized, late-bound services such as security, fault-tolerance, and billing. Unfortunately, such services have implementations that transcend module boundaries; heterogeneity, and distribution worsen this problem. We present DADO, an approach to extending middleware to bring some of the same advantages to service developers that middleware offers to application developers: design models, heterogeneity, separable implementation, static type-checking, automated generation of ``plumbing" code for handling communication details, late binding, etc. We present the design rationale of DADO, and offer some preliminary performance data that suggests that the added programmer convenience comes at an acceptable run-time overhead.
This is joint work with 2 Ph.D. Students (Eric Wohlstadter, and Stoney Jackson) and one undergraduate (Derek Pallas). We gratefully acknowledge support from NSF (CISE/SE&L and ITR programs).
