The Backplane Structure Of The Router

The core of the router is the backplane, and an efficient backplane helps improve the performance of the router. Since the traditional shared bus backplane cannot meet the needs of routers, a switched backplane whose structure can be implemented with different technologies is adopted. Banyan structure, Crossbar structure and parallel shared storage structure are commonly used structures for switching backplanes. Banyan structure adopts self-routing technology and multi-level buffer structure; Crossba structure is single-level, single-channel, non-blocking structure, and adopts full Internet switching structure; parallel shared storage structure is a research hotspot.
