Failure detection in virtual network environment

In virtual network, a substrate network and its software are prone to failure. This can lead to failure of all the virtual resources hosted by that substrate network. This will require the remap of the virtual network to different substrate network resources. This can be avoided if we can predict the failure early and take corrective actions. Thus, detecting a virtual network failure is an important issue to overcome the failure in a virtual network and to enhance the virtual network dependability. In this paper, we present a virtual network failure detection mechanism based on a conservative time-synchronization algorithm and message passing interface. We also present performance analysis to show the effectiveness of the proposed failure detection algorithm.
