Analysis of processing time between distributed geometric modeling systems

In recent years, the concept of distributed systems has been applied to industries to enable cooperative work and collect distributed information. A distributed geometrical modeling system has been developed to share the functions among the systems on the network with a peer-to-peer (P2P) structure. The systems that are linked on the network can use functions of other systems. Such a network can perform operations concurrently by using other systems, which saves time. The importance of constructing this kind of distributed CAD system is to transfer three-dimensional (3D) CAD model data and access the locations of providers. The developed system has a sharing of functions, which consist of client (requester) and server (provider) as a P2P system, and is constructed by using a CAD kernel and COM/DCOM technology. Simple operations have been performed and tested by the developed system, such as Boolean operation, obtaining properties, triangulation and tessellation. The developed system has been evaluated with stand-alone and client–server systems for simple operations based on two criteria. In the first evaluation, the processing timings have been compared for simple operations among the systems: the stand-alone system is faster than the other systems. In the second evaluation, the systems are overloaded and the processing timings have been compared: the developed system is faster than the other systems.

Research highlights
► The developed modeling system consist of client (requester) and server (provider) as a P2P system.
► Geometric modeling systems can share functions with each other on the network.
► Processing timings have been compared for simple operations among three systems.
► When the operation is overloaded, the P2P structure enables faster calculation than the others.
