Real-time & Embedded Systems Forum
(Wednesday)

Objective of Meeting

There were several objectives for Wednesday that were specific to sub-sessions and presentations.  As several different topics were covered throughout the day, we will highlight the specific objectives in the summary and the output sections.

Summary

Mission Assurance

This session featured Harriet G. Goldman, Director of Cyber Mission Assurance, serving as the MITRE focal point for Mission Assurance in support of the Department of Defense and Intelligence customers, responsible for raising awareness of the advanced cyber threat across government and industry and developing strategies, technologies, and processes to address customer cybersecurity and mission assurance needs.

Harriet offered a very good look at what Mission Assurance means and why it is so important.  She drove home the need to collectively work together to develop cyber solutions and response strategies and to define mission assurance best practices.

Mission Assurance Business Scenario Workshop

This workshop was conducted by Terry Blevins, Chief Architect and Associate Department Head, MITRE.

Terry followed up on Harriet’s presentation by exploring what Mission Assurance meant to the participants, by asking each participant to express what pain-points their organizations or they personally experience when faced with the consequences of not having mission assurance. 

Sally Long captured the pain-points and will publish them to the group as the first step in the Business Scenario Exercise. Sally will also investigate where in The Open Group might be the best place to evolve the larger collaboration effort on Mission Assurance – the RT&ES Forum felt that they could contribute to their domain-specific piece of that collaboration.

DoDAF 2.0

Glen Logan, Chair of the RT&ES Forum, reported on the latest release and support for DoDAF 2.0.

He gave a very good presentation on the newest release of DoDAF – what relevant changes there have been and what that might mean for architecting real-time solutions.

TOGAF RT&ES Extension and RT&ES Reference Model

Edwin Lee from Raytheon started off this session with some slides and discussion on the RT&ES Reference Model, and the presentation was continued by Ed Roberts, Elparazim, who presented the work and discussion thus far on extending The Open Group Architecture Framework (TOGAF) for high-assurance architects and the real-time environments.

SysML Tutorial

This overview and tutorial was provided by J.D. Baker from the Armstrong Group and Ed Roberts from Elparazim and was open to both the Architecture and the RT&ES Forums.

J.D. Baker provided a very good information session on how to use SysML and its applicability to real-time solutions.  This session was of particular interest to those looking to refresh their skills and knowledge base as applicable for modeling TOGAF 9 and for creating real-time plug-ins.

MARTE

Ed Roberts presented a quick overview of MARTE, which when used in conjunction with AADL and SysML, may be what the RT&ES Forum requires to create their high-assurance plug-ins for modeling RT&ES extensions for TOGAF.

Open Systems Architecture Guide

Edwin Lee from Raytheon provided a great presentation of his work on the Open Systems Architecture Guide.

He also offered an impressive look at the RT&ES Wiki. His presentation is extracted from the Wiki, so if you are an RT&ES Forum member please have a look at The Open Group Councils' Wiki, and follow the RT&ES link in the left-hand navigation bar.

Architecting for Uncertainty

This was a joint session with the Security Forum during which Mike Jerbic presented his ideas on Architecting for Uncertainty from a security perspective and facilitated discussion on whether and how that concept could be extended to real time.

The ultimate objective of this exercise would be to see whether there was enough synchronicity with this concept within the two groups to arrive at one template for a high assurance/security approach to extending TOGAF for their respective needs.

JSR 302 Expert Group Specification for Safety-Critical Java

Doug Locke, LC Systems Services, presented the status and future plans for Safety-Critical Java (JSR 302).

Joe announced that the Safety Critical Java Group has reached a major milestone in completing the JSR 302 specification. This was announced at The Open Group Plenary as well – so a round of congratulations was extended to all!

Outputs

Refer to Next Steps.

Next Steps

Mission Assurance:

• Sally Long to refine and distribute the notes on Mission Assurance Pain Points, collected during the Business Scenario Workshop.
• Sally Long to investigate where Mission Assurance might fit in the RT&ES Forum or in any of the other Open Group Forums.

Modeling for RT&ES Plug-ins to TOGAF:

• Many different modeling languages were presented during these sessions. The RT&ES Forum intends to settle on one or a combination of languages to meet their needs. In order to facilitate that decision, Ed Roberts will provide a Matrix of the various languages and the functionality they offer with respect to real-time and formal methods, so that the RT&ES Forum can make a more informed decision and move forward on the actual plug-in creation.

Architecting for Uncertainty:

• The RT&ES Forum will be reviewing one of Mike Jerbic’s charts that illustrates the Security Forum’s mapping of uncertainty principles to the TOGAF ADM – to what they would do the same or differently in that mapping from a high-assurance real-time perspective.
