IPv6 Backbone Network Topology (A Map of Ipv6 Internet)

The IPv6 Group is a part of the State Key Laboratory of Software Development Environment(SKLSDE) in BUAA, China.We took up with research on IPv6 backbone network topology discovery,modeling and analysis.

Dolphin is our IPv6 backbone network topology discovery system, based on asynchronous traceroute probe.With the help of Dolphin,we are able to obtain some topological information of the IPv6 backbone network.

Until 2009.3.12 21:00,we have found 632 ASes, 16312 routers and 116600 links.

New system is under development, so the results will not be updated until we finish the new one.

	During the last three monthes...
AS:			29	Interface:			1890	Link:			15430

Kinds of visualization tools we developed faciliates the display of topological infomation and analytical findings. Based on the data collected, we also established IPv6 internet network model to interpret the new metrics of IPv6 internet network topology.And at the same time,we presented some new algorithms in complex network analysis.

Our future work includes measurements on the links,analysis of complex network robustness.

The following pictures displays our recent IPv6 backbone topology discovery and display results.
