Executive Summary

Recently network virtualization has been proposed as a promising approach to thwart the current ossification of the Internet by allowing multiple heterogeneous Virtual Networks (VN) to coexist on a shared infrastructure which itself is controlled by self-interested infrastructure providers. A major challenge in this respect is the VN embedding problem that deals with efficient mapping of virtual nodes and virtual links onto the substrate network resources. Most previous research on this problem has focused on designing heuristic and approximation algorithms for the VN embedding problem. However a common aspect of these previous results is that they assume that the different stake-holders in the network virtualization environment do not act in strategic ways.
