This work is aimed at visualizing the dynamic behaviour of very large communication networks. The visualization of large graphs and networks is a crucial part of many applications, for which typical approaches are too demanding of computational resources. Since one of the most important issues is a visualization of the dynamic behaviour of graphs, special aspects of the visualization of huge graphs with dynamic behaviour are discussed. The paper describes an algorithm that speeds up the visualization of very large graphs and provides fast access to underlying data structures. It provides an adaptive data structure for general dynamic graphs and discusses the adaptation of this structure to very large communication networks. Our method supports several special tools for efficient analysis and evaluation of the graphs representing communication networks.

Future Internet is...

With over a billion users, today's Internet is arguably the most successful human artifact ever created. The Internet's physical infrastructure, software, and content now play an integral part of the lives of everyone on the planet, whether they interact with it directly or not. Now nearing its fifth decade, the Internet has shown remarkable resilience and flexibility in the face of ever increasing numbers of users, data volume, and changing usage patterns, but faces growing challenges in meetings the needs of our knowledge society. Globally, many major initiatives are underway to address the need for more scientific research, physical infrastructure investment, better education, and better utilisation of the Internet. Within Japan, USA and Europe major new initiatives have begun in the area.

To succeed the Future Internet will need to address a number of cross-cutting challenges including:

Scalability in the face of peer-to-peer traffic, decentralisation, and increased openness

Trust when government, medical, financial, personal data are increasingly trusted to the cloud, and middleware will increasingly use dynamic service selection
