Future network should flexibly deal with unexpected network changes caused by the diversification of the network services. In this paper, we propose a managed self-organizing network concept and a dynamic resource allocation mechanism, called as DRAMS. In the managed self-organizing network, multiple virtual networks are accommodated on a single physical network and controlled autonomically based on self-organization. Due to the sharing of limited physical resources, resource contention among virtual networks will be inevitably caused. To cope with this issue, we introduce a dynamic resource allocation to regulate the resource usage of ill-behaved virtual networks. Our research goal is to establish a management mechanism for controllable self-organizing networks. The proposed mechanism allows self-organizing control by virtual networks and just indirectly controls the behavior of virtual network in order to avoid resource contention and improve resource efficiency.
