RTESS Roadmap Dock Allen

1
RTESS RoadmapDock Allen

• Briefing to C4I, November 3, 2004
• Objective
• Establish priorities
• Coordinate WorkC4I/2004-11-26

2
Topics

• Who we are
• Work in progress
• Potential new RFPs
• Other areas of interest
• Process and Technical Issues
• Overlaps and Priorities

3
RTESS

• Focal point OMG technologies for specialized
  systems. E.g
• Real-time Systems
• Hard real-time, Soft real-time, Interactive
  real-time
• All things temporal
• Fault Tolerant / Highly Available Systems
• Embedded Systems
• High Performance Systems (e.g. parallel
  processing)
• Safety Critical Systems (and some Security work
  where there is overlap)
• MO Adapt existing specifications
• Minimum CORBA, RT CORBA, FT CORBA
• Sponsor new specs where needed (e.g. DDS, GNC
  client)

4
Work in Progress (likely C4I interest)

• GNS Client Interface (recommended)
• RT Notification (real-time)
• Model-based Test and Debug (recommended)
• High Assurance CORBA (safety critical)
• Power Conservation Services (embedded)
• Reliable Ordered Multicast for CORBA (High
  performance)
• High Performance Enablers (will be recommended
  this week)

5
RTESS Roadmap (1 of 3)

• O/S adaptation service
• Primarily for RT and embedded systems
• Portable OO interface to commonly used OS
  (Windows, Linux, Posix, COTS RTOS) services
  (threading, timers, etc)
• Capture current practice (such as ACE)
• Not tied to RT CORBA or DDS, but must be
  compatible
• QoS-aware MoM Services
• A trend in some embedded RT systems
• Ideal support JMS, W3C MEP, and COTS RT
  messaging
• Ideal compatible with/ composable with DDS and
  CORBA
• Not Enterprise MoM (too many big non-OMG
  vendors)
• Real-time Fault Tolerance (possibly a framework)
• Standard Real-time CORBA protocol

6
RTESS Roadmap (2 of 3)

• Extensions to DDS
• DDS interoperability and middleware interworking
  (MARS)
• Lightweight, QoS, threading, RT interworking
  (RTESS)
• QoS-aware J2EE
• Probably not an OMG initiative, but want to gauge
  interest
• Critical to QoS-sensitive web services and
  Net-centric operations
• Additional High-Assurance profiles
  /specializations
• Possibly DDS and important services
• Dual-access services (e.g. CORBA and DDS)
• Time as published data??
• GNC client??

7
RTESS Roadmap (3 of 3)

• UML-simulation integration
• Likely item for resurrected SIMSIG (may start in
  RTAD)
• Probably run-time (versus model transformation)
  integration
• HLA? DIS? Other
• A possible scenario for executable UML
• Support for MDA in sim-based acquisition
• Protection Profile for Middleware
• Initial look in January
• New UML Profile for RT, Embedded systems
• Opportunity to work in Aspect-oriented modeling
• Aspect-Oriented Modeling / Design / Programming
• UML profile for System-on-a-Chip (SoC)

8
Other Items of Interests to RTESS

• Load Distribution (MARS)
• Possible future lightweight and QoS extensions
• Executable UML (ADTF)
• QoS/embedded impacts
• Relationship with model-based test and debug
• CMS (C4I)

9
Process issues

• Light-weight process doing common specializations
  of OMG specs?
• E.g. lightweight profiles
• Light-weight process for adding a new interface
  modes to a service?
• E.g. Time available through DDS
• Light-weight process for synchronizing specs
  (e.g. bringing Minimum CORBA up to CORBA 3.0)?
• Scenario-based interface factoring, possibly
  using UML?
• A more rigorous process for subsetting?
• A way to standardize frameworks and PIMs where
  there is no implementation

10
Technical Issues

• Middleware interworking and composability are
  becoming critical issues
• DDS, CORBA, and CORBA Events being used together
  what is the standard?
• Not just coexistance, but also the ability to
  exchange application entities (data-events)
• MDA support for
• Integration of PIMs into legacy systems
• Re-architecting the PIM Versus rearchitecting /
  wrapping the legacy
• Managing performance issues
• QoS and other ilities
