Abstract: Point to Point Protocol(PPP) is a popular link layer protocol with the characteristic of high efficiency and authentication. This article offers a design based on virtual drive adaptive layer that focuses on the distributed designation of high-performance router. And it focuses on the realization of the PPP virtual drive module in RAL framework. The module offers the upper software well shield and simulation of the devices. So it satisfies the software-hardware independent design, improves the extension and maintenance of the system. Experimental result shows that the scheme is highly effective and stable. And it is easy for maintenance and migration.
