Sharing CAD applications

The work presented in this paper has been partially funded by the EC under the TEN-IBC projects B1013 and B2013 "IDEA" and partially funded by Finsiel. The technology of shared window systems is presented and its application to the special requirements of design centers in the car industry, is addressed. The work focuses on the issues of market availability, network access, and bandwidth requirements providing also an evaluation of overhead introduced by the protocol stack adopted to perform the end-to-end communication. The technologies presented in this paper have later been experimented and evaluated not only over Ethernet LANs, but also over national and international PEAN links. The observed values show that the tested CAD packages can be effectively used alone over 2 Mbs links in a point-to-point configuration also considering the typical big size of CAD models used in the car industry.
