Common Object Request Broker Architecture

چکیده
The rapid developments in the internet software technologies in the wireless networks need platform and language neutral distributed object-oriented components to manage and use different mobile devices and to provide services on top of them. In this paper, we evaluate Common Object Request Broker Architecture (CORBA) which is widely used middleware in the wireline network and present the performance results in different wireless systems.We found that message formats for communication between different Object Request Brokers (ORB) as defined in General Inter-ORB Protocol (GIOP) are optimized and further optimization will only result in reduced interoperability. We present a way of implementing and using CORBA in a wireless network and the results obtained. We present the use of the Mobile IP at the network layer which takes care of Mobility and handoff without requiring any change in the ORB. Thus we demonstrate a working implementation of Mobile CORBA. We suggest number of further improvements that should be incorporated in any implementation of CORBA to be used for wireless applications.

متن کاملThe Broker Architectural Framework
According to Andrew S. Tanenbaum distributed systems have a significant drawback: “Distributed systems need radically different software than do centralized systems”. This is the major technical reason for consortias such as the Object Management Group (OMG) or the Open Software Foundation (OSF) and companies such as Microsoft developing their own technologies for distributed computing. Platfor...

It is well known in the research community, that today’s middleware solutions like the Common Object Request Broker Architecture (CORBA) implementations or Microsoft’s Distributed Component Object Model (DCOM) are not suited for distributed multimedia systems. For example, there is no explicit representation of communication (explicit bindings) and no QoS support as required by multimedia appli...
