Network update enables Software-Defined Networks (SDNs) to optimize the data plane performance. The single focuses on processing one event at a time, i.e. , updating set of flows from their initial routes target routes, but it fails handle continuously arriving events in time incurred by high-f...

Nowadays, a massive amount of data leads to cause network traffic and inflexible mobility in future mobile networks. A new Group Mobility Model (GMM) named MoMo is introduced that addresses the issue aforementioned problems. Even though, software defined (SDN) functional with network-rooted protocols enhance efficiency. Some existing administration methods still undergo handover delay, packet l...

The hybrid software-defined networks (SDN) architectures are beneficial for a smooth transition and less costly SDN deployment. However, legacy switches coexistence brings new challenges of deployment inconsistency management security. Security is not well studied architecture. In this paper, we study the topology poisoning attacks in first time. We propose attack vectors link fabrication SDN. ...
