摘要

Network virtualization allows multiple logical networks to coexist on the same physical infrastructure. A key problem that needs to be solved in this context is management of substrate network resources, in particular when mapping virtual network requests to the substrate. Several efficient algorithms have been proposed to provide effective solutions, but they assume that the virtual network request topology is given. In this paper, we show that the use of these topology-based requests may limit the efficiency of physical network usage. As an alternative, we propose a problem formulation and mapping algorithm that is based on traffic matrices to specify virtual network requests.
