   <dc:description>We present an approach for deploying and subsequently managing a virtual network overlay, which is tailored to an end-user’s request. Our approach combines a binary integer optimisation process to decide on the number and placement of virtual routers, and an autonomic network management system&#xd;
that subsequently manages the configuration of the running virtual network. High-level optimisation policies are used to guide&#xd;
the optimisation process to identify a virtual network that favours lower hosting costs or higher network quality (we use mean&#xd;
delays as a quality metric). Low-level deployment policies are generated and used to govern the deployment and management&#xd;
of the virtual networks. Our results indicate that the binary integer optimisation process produces a virtual network that has lower cost as compared to creating a network based on combined&#xd;
shortest paths.</dc:description>
