Decorrelation of networked communication flow via load-dependent routing weights — •Jan Scholz1 and Martin Greiner2 — 1Frankfurt Institute for Advanced Studies, Johann Wolfgang Goethe Universität, Frankfurt am Main, Germany — 2Corporate Research and Technology, Information & Communications, Siemens AG, München, Germany
Clever assignments of link weights are able to change the routes in communication networks in such a way that loads are distributed almost evenly across the network. This is achieved by weight assignments based on link load. As demonstrated for scale-free as well as synthetic Internet networks they decorrelate the loads of the nodes and links from the network structure and increase the transport capacity of the network. For various Internet scans the increase of transport capacity amounts to a factor of around five when compared to shortest-path routing.
