Practical explicit binding interface for supporting multiple transport protocols in a CORBA system

This paper proposes an extension to the standard CORBA interfaces to support explicit binding. The extended interface enables a program to select a suitable transport protocol for each method invocation, and it provides a flexible and versatile framework to control various transport protocols. The interface is compatible with the object model of CORBA, and it is carefully designed to take into account the portability of an application to other CORBA implementations. The extended interface has implemented in omniORB2, which is a CORBA 2.0 compliant system that has been developing at AT&T Laboratories, Cambridge.
