| In recent years, network virtualization has been proposed as a long-term solution to the gradual ossification problem faced by the current Internet and a harbinger of future network. By allowing multiple heterogeneous network architectures to cohabit on a shared physical substrate, network virtualization provides flexibility, increased manageability, promotes diversity and promises security. One major challenge on network virtualization is the resource management of substrate networks. The exiting research are mostly focus on design algorithms for mapping virtual networks to a substrate networks, but neglect maximizing the resource utilization dynamically in a constantly changing substrate network environment. In this paper, we propose a distributed autonomic resource management mechanism to optimize the substrate network resources. In this mechanism, cooperative work agent running in each substrate node can manage resource in the substrate network dynamically. The simulation shows that our mechanism brings considerable benefit in resource utilization. |
