Paper Abstract:
|
There are some difficulties in developing a highly efficient content delivery system: where to deploy contents or replicas, real-time event handling, and selecting optimal network paths in terms of QoS and costs. We tackle these issues by combining a probabilistic contents/replicas deployment mechanism, a real-time event notification system and OpenFlow technology. In this paper, we especially describe the performance evaluation of our probabilistic replication technique which is a core component of ConTrail by simulations. The results show that our approach can reduce the average latency for contents acquisition more than existing approaches. Moreover, we describe how to achieve the QoS and save network costs by choosing suitable communication flow with OpenFlow. |
