Transcript

  • 1. CCM From CORBA Component Model To Common Component ModelCopyright © 2011 Page 1
  • 2. CCM Application Development CycleCopyright © 2011 Page 2
  • 3. CCM Exists as Component Model for more than a decade Several implementations available Platform and programming language independent Accepted into a large amount of projects because it is an open standardCopyright © 2011 Page 3
  • 4. DDS4CCM Specification-level support for using/configuring DDS within the context of CCM Introduced the concept of IDL3+ and connectors, soon part of CORBA 3.2 Specifies DDS QoS settings through XMLCopyright © 2011 Page 4
  • 5. Deployment viewCopyright © 2011 Page 5
  • 6. DDS4CCM Implementation available as part of CIAO – RTI currently the only supported DDS vendor – Designed in an extensible manner so that other vendors could be supported Component Based DDS (CBDDS) – Simplifies D&C of DDS-based applications – Reduces tedious & error prone boilerplate code for QoS configuration – Potentially allows for DDS implementations to be chosen at deployment time vs. compile/design timeCopyright © 2011 Page 6
  • 7. AMI4CCM Asynchronous invocations for CCM – Does not require CORBA AMI support – Details of asynch invocation hidden from component business logic Set of implied IDL rules – Creates implied connector and interfaces used by component business logic – Currently requires annotation through preprocessor macros – Interfaces modeled off of CORBA AMI AMI4CCM connectorCopyright © 2011 Page 7
  • 8. Deployment viewCopyright © 2011 Page 8
  • 9. AMI4CCM Standardization OMG RFP issued December 2010 Draft initial submission available Reference implementation available as part of CIAOCopyright © 2011 Page 9
  • 10. Built-in event support CCM has built-in support for events – Not very flexible or extensible – Requires container-level support for new event passing mechanisms Currently part of the core CCM specification Mostly not used with CBDDS Proposal to move this to a connector that can be much more powerful than the existing event supportCopyright © 2011 Page 10
  • 11. Extensibility Past solutions resulted in heavy containers and deployments tools – Tight integration between CCM implementation and D&C toolchain – Container-level code modifications required for new features Revised approach is to provide interceptor support at various levels – Locality (D&C toolchain) – Container – ComponentCopyright © 2011 Page 11
  • 12. Improved Language Mappings Current component executor programmers find the mappings hard to use C++ is a real challenge and needs to be improved Java and C can also be improved New set of base classes specific to CCM For CCM not all IDL supported features need to be availableCopyright © 2011 Page 12
  • 13. Modeling support CCM/D&C needs adequate modeling support Multiple vendors for CCM/D&C – CoSMIC – Atego – Zeligsoft D&C specification provides XML-based meta-data exchange format for modeling toolsCopyright © 2011 Page 13
  • 14. What do we want to do? Migrate from CORBA Component Model to a Common Component Model – Decouple from CORBA specification – Make CORBA ORB an optional middleware bus Extensibility CCM & D&C through plugins QoS4CCM extensions for LifeCycle Improved language bindingsCopyright © 2011 Page 14
  • 15. What do we need? Input from users about improvements Support from the modeling tool vendors for the new features Funding to prototype, implement, and standardize the various extensionsCopyright © 2011 Page 15
  • 16. Thanks for your attention Johnny Willemsen <jwillemsen@remedy.nl> Marcel Smit <msmit@remedy.nl> http://www.theaceorb.nlCopyright © 2011 Page 16
