Abstract
Efficient and predictable demultiplexing is necessary to provide real-time support for distributed object computing applications developed with CORBA. This paper presents two contributions to the study of demultiplexing for real-time CORBA endsystems. First, we present an empirical study of four CORBA request demultiplexing strategies (linear search, perfect hashing, dynamic hashing, and active demultiplexing) for a range of target objects and operations. Second, we describe how we are using the perfect hashing and active demultiplexing strategies to develop a highperformance, real-time ORB called TAO. Keywords: Communication software, Real-time CORBA, Demultiplexing. 1 Introduction CORBA is a distributed object computing middleware standard defined by the Object Management Group (OMG)[14]. CORBA is designed to allow clients to invoke operations on remote objects without concern for where the object resides or what language the object is written in. In addition, CORBA shields applica...
