Open Implementation Toolkit for Creating Adaptable Distributed Applications
QuO version 3.0 is now available
BBN Distributed Systems Project -- Technical Overview
Large scale information systems are often vulnerable because their implementation relies on a single strategy throughout to achieve desired functionality. This single implementation approach has inherent limitations in its adaptivity and, if compromised or flawed, can result in total unavailability. One promising way to improve survivability from attack is through adaptable mechanisms which allow detection of non-compliant behavior and permit reconfiguration using alternative but functionally equivalent implementations.
The Open Implementation Toolkit project will improve the way systems are developed by extending current distributed object computing, e.g., CORBA, concepts to make explicit the resource usage implications associated with alternate implementations. This information serves as an information base for providing runtime mechanisms detecting violations of desired operating (survivability, security, performance) ranges, and for dynamically reconfiguring using an alternate implementation. We will provide these innovations through a distributed object toolkit.
This project is funded by DARPA ITO under the Information Survivability, Survivability of Large Scale Systems program.
