Abstract
The immense growth of client requirements imposed on data centre and cloud providers results in a conflict with traditional networking concepts lacking the required agility. In order to promote flexibility, which data centre providers promise to their clients, this discrepancy needs to be resolved, for instance by employing the novel concept of Software-Defined Networking (SDN). This paper utilises this concept in order to minimise service downtime while performing live virtual machine migration. The work is aimed at small/medium-sized data centres and hence the findings are based on real communication patterns found in such environments. Results show that packet loss is slightly diminished while available throughput is increased thanks to the proactive approach taken during network topology changes when compared to the traditional approach based on L2 forwarding.

Traditional networking principles fail to comply with the requirements mentioned above, notably flexibility when it comes to creating new virtual networks and applying security policies
The findings show that available throughput during the critical phase of live virtual machines (VMs) migration is approximately doubled when compared to the traditional, non-Software-Defined Networking (SDN)-based approach
Summary
In the last couple of years, the business has largely focused on improving its efficiency. The set of requirements held by clients affects how cloud providers organize their internal data centre networking topology. The requirement of flexibility and scalability, expressed by building numerous virtual machines (VMs) and virtual networks practically instantaneously, must be considered when employing a particular network design. Traditional networking principles fail to comply with the requirements mentioned above, notably flexibility when it comes to creating new virtual networks and applying security policies. Networking has long been known for the burden of configuring every device separately. Each device, be it a switch or router, represents an independent instance with its own logic. The distributed concept of control plane hinders flexibility as required by customers
