Processors Communications in the Context of Virtual Switch Framework Using the CAN-IOP Protocol

A CORBA-compliant object request broker (ORB) can facilitate data communication between dissimilar hardware, dissimilar operating systems, and modules written in different languages. Thus, in our proposal all control and management communication occurs within the context of the ORB. Our idea is based on a conception of a free architecture as a CORBA-based middleware for distributed embedded systems built on the CAN bus that realize a virtual switching architecture. This platform has to connect different physical network types. Thus we propose a solution to make it to behave as a router or a switcher. In our proposed framework we will use an ORB that may be conform to the forthcoming Real-time CORBA standards to be embedded in a network switch. Our target switch control environment includes support for virtual switching interface (VSI) which is a protocol that allows multiple independent signalling processors to interact with a switch control processor. The scope of this paper is to conceive an application that controls a such switch using the VSI messaging protocol within the context of embedded ORB over a free distributed and real-time embedded (DRE) architecture built on the CAN bus.
