A'b s t rac tThis paper discusses the goals, components, and concepts of the CAMPUS project, which aims at providing an intelligent Broadband ISDN server, using previously developed building blocks, like a switching fabric, ATM interfaces, and host interfaces.Intelligent networks will need a lot of distributed processing power. That is why CAMPUS uses a multiprocessor architecture as well for the computing as for the communications, which makes it very regular and scalable. In addition, it includes fault-tolerance at all levels.
