Introduction
This paper describes an implementation of distributing engineering services over the 2 infrastructure. Specifically, pare the run times of a wheelchair analysis of a Stanford University building distributing the engineering analysis over works:
The internal Stanford work ().
The traditional backbone between Stanford and Illinois Institute of Technology (IIT) Main Campus.
The 2 backbone between Stanford and the University of Illinois at Urbana-Champaign (UIUC).
From parisons, we gain a better understanding about the strengths and weaknesses of various elements of our implementation choices including the distributed object environment, the distributed analysis architecture, and the wheelchair simulation. In addition, we discuss the advantages or lack thereof of the 2 backbone over the traditional .
The Distributed Architecture
This study extends the work presented in [1] and [2] that describe an architecture to distribute engineering services over the . Figure 1 illustrates the three-tiered distributed architecture:
The first tier consists of munication protocol which allows the services municate with each other.
The second tier consists of an mon product model interface.
The third tier holds the actual analysis module of the service.
The prototype uses CORBA for its munication protocol, and most of the services are implemented using the Java programming language [3]. Note that services can register with other services to aggregate and posite services.
Figure 2 shows the implemented services in the pr
