QoS Driven for CAD-Grid Integrated System

This paper describes the distributed resource management for QoS driven for CAD-Grid integrated system. In this work, system actualization mode, architecture and function module are discussed in building a distributed QoS driven for CAD-Grid system. An emphasis has been placed on making the tools interactive, in an effort to create a user friendly environment. The goal is to provide an efficient and reliable method for model development, visualization, and CAD model quality evaluation. Numerical simulations are given to illustrate that the system is completely open mode, expansibility, compatibility with high safety which can support cooperative dynamic work and realize resource sharing.

I. Introduction

Quality of Service (QoS) refers to the capability of a network to provide better service to selected network traffic over various technologies, including Frame Relay, Asynchronous Transfer Mode (ATM). With the development of internet, mobile networks and high-performance networking technology, QoS multicast routing has become a very important research issue in the areas of networks and distributed systems[1]. Currently, many people focus their study on how to select their services according to their QoS in order to make the composite service meet users' constraints and exhibit better runtime quality.
