An Experimental Study on Dynamic Network Reconfiguration in a Virtualized Network Environment Using Autonomic Management
In a virtualized network, network virtualization is achieved by creating multiple instances of virtual routers over existing physical routers. Critical aspects of network virtualization are resource allocation and resource re-allocation, especially in the case of router failures or re-allocation of routers due for maintenance. In this paper, the authors present a dynamic network reconfiguration scheme that can provision a new virtual network and recover it from router failures using autonomic management. In order to provide a highly available virtual network, their approach considers replacing failed routers with the most suitable standby routers.
