Switched bus in information system-principal and design

Two kinds of bus architectures are compared. Because of bandwidth limitation of shared bus, it is the bottle-neck of system's performance. Switched bus is more capable and scalable. In modem server and router, high-speed serial link and cross point switch is the current trend of technology. A prototype point-to-point 1.25 Bbps backplane is described, the BER of which is less then 1E-12.
