In the context of Software-Defined Networking (SDN), various sophisticated policy-aware network functions such as intrusion detection, access control and load balancer, can be realized via specified middlebox devices. However, high congestions may occur in specific bottleneck links if middlebox selection and traffic routing are not well jointly planed. To this end, we study a joint optimization of...
With various cloud services emerging in data center networks, network congestion and load imbalance are seriously caused by elephant flows. To resolve this problem, a load balancing mechanism based on software defined networking (SDN) for elephant flows is proposed. The mechanism obtains the topology and status of the entire network via global view of SDN. Then it splits and sends elephant flows through...
