    RE: What is ORB?

    Object request broker (ORB) is the entity responsible for managing requests for objects. ORB accepts method call requests from client applications, locates the target of calls and transmits the request to that target. ORB is usually implemented as a software library that is linked with CORBA applications. Many vendors provide different kinds of ORB implementation. Free and open-source implementations are also available.



    The light blue elements in figure above are defined and implemented by the user. After the IDL interface definition, a compiler is used to automatically generate the stub and skeleton, and commercial ORB implementations are readily available. The block arrows show that client code calling a method on the server only sees a local method calls; no different from the mundane method-calls in non-distributed programming. The ORB, together with the generated stub and skeleton code, hides the distribution completely.

    Nokia offers ORB implementation and OS wrapper to some RTOS. For more information about ORB, see http://www.forum.nokia.com or http://www.americas.forum.nokia.com.
