The Backplane Structure Of The Router

The core of the router is the backplane, and a high-efficiency backplane helps improve the performance of the router. Since the traditional shared bus backplane cannot meet the needs of the router, the switch backplane is used with different technologies. The Banyan structure, Crossbar structure, and parallel shared storage structure are common structures for switched backplanes. The Banyan structure adopts self-routing technology and multi-level buffer structure. The Crossba structure is a single-stage, single-path, non-blocking structure, which adopts the all-Internet switching structure; Parallel shared storage structure is a hot spot in research.
