Dependability Engineering for Open Systems (DEOS) and O-DA Framework - Retrospect and Prospect
Mario Tokoro, Founder and Executive Advisor, Sony Computer Science Laboratories, Inc.
Today, most of the social infrastructures and businesses are supported by huge and complex software systems that must be dependable to provide sustainable services. These systems are used for a long period of time being modified constantly due to changes in service objectives, users’ requirements, regulations/standards and technological innovations. These systems are often mutually connected by networks to exploit external services and to be executed on clouds. DEOS was designed to attain dependability of such systems. It consists of
Dependability Engineering for Open Systems (DEOS) process that integrates processes for the development and operation,
D-Case which is the method to attain and describe stakeholders’ agreement, and
DEOS architecture which includes the execution environment (OS) and the database that preserves the record of agreements described in D-Case.
The concept and the design of DEOS contributed to the Dependability through Assuredness™ (O-DA) framework, a standard of The Open Group. In this speech, decisions which made DEOS evolve to the current design will be presented first. The author will then discuss O-DA and its future in conjunction with The Open Group and TOGAF®
Dr. Mario Tokoro is the head of the DEOS project funded by Japan Science and Technology Agency (http://www.dependable-os.net/index-e.html). He established Sony Computer Science Laboratories, Inc. (http://www.sonycsl.co.jp/en/) in 1988 and led it to be one of the world-renowned fundamental research laboratories. He joined Sony Corporation in 1987 to become Corporate Senior Vice President, and then assumed to be CTO in 2000. He promoted networked consumer electronics by introducing architecture-based design and common software platform for consumer electronics products. He played the central role in the establishment of Consumer Electronics Linux Forum (http://www.celinuxforum.org/), CELF in short, which was absorbed in Linux Foundation in 2010 to form the CELF workgroup. Before joining Sony Corporation, he was Professor of Computer Science at Keio University, and held visiting positions at University of Waterloo, Carnegie-Mellon University, GMD, and University of Paris VI.
