Research of the topology auto-discovery approach in the IPv6 access network

For processing effective IPv6 network´s management, it is crucial to carry out network topology discovery based on the characteristics of IPv6 network. Most research at present mainly focused on the approaches of IPv6 backbone network´s topology discovery, but there´s hardly any exploration to the approach of IPv6 access network´s topology discovery. A strategy of topology discovery in the IPv6 access network is to be proposed in this paper. The correctness and the effectiveness of our approach are also to be analyzed through some tests in the end.
