Telepresent Agents: A New Paradigm for Networked Systems
Conference: Proceedings of the International Conference on Parallel and Distributed Processing Techniques and Applications, PDPTA '04, June 21-24, 2004, Las Vegas, Nevada, USA, Volume 3
Telepresent Agents are software Agents that are instantiated simultaneously within two or more distinct computer applica- tions (called Locales) which are operating at distinct nodes of a computer network. Agents are composed of Capabilities—often a separate Ca- pability for each Locale in which the Agent op- erates. As an Agent exchanges information among and within its Capabilities, information passes implicitly among the Locales as if through a wormhole communication channel. One way to think about SimX—our name for the mechanisms described here—is that its does for data shared among Locales and Remote Proce- dure Calls what object-oriented programming did for instance variables and subprogram calls. By providing an entity-like construct within which such calls and data can be encapsulated, a construct that cuts across Locale boundaries, SimX eliminates the need for explicit mecha- nisms to allow Agents and Locales to communi- cate directly.
