6to4 Tunnel Drive Research and Realization on High-end Routers

摘要

In this paper we designed a set of driving process in order to achieve the IPv6 network connectivity between the isolated IPv6 islands which can instruct tunnel packet to forward on the chips. First, it introduces 6to4 tunnel, system structure and the process of chip forwarding. Then it introduces how the drvier respond to the platform and write the correct message on the chip after processing. Experimental results show that the driving process can instruct 6to4 tunnel packet to forward on the NP chip very well. The result is good and has strong practicability.
