SDN-Based Batch Flow Routing in CamCube Server-Only Data Center Networks

According to the latest statistics, the number of connected people to Internet is still exponentially growing and the high quality of cloud services is significantly requested in the incoming years. In addition to that, the appearance of big data, blockchain and bitcoin motivate more and more scientists and experts in this field to fight for the first place with the most attractive products in terms of performance and utility for their customers. But, what about the resilience and the reliability of the infrastructures accommodating these services? It is undeniable that the rapid growth of this traffic inside data centers network, caught cloud experts attention's appeal. Also, proposing algorithms and solutions for traffic management becomes essential. In this context, we study the improvement of network QoS performance for intra-data center flows in CamCube server only topology. We have already addressed in previous works the routing problem for online traffic (unicast and multicast) within CamCube topology. Our experimentations show a satisfying results. However, facing this important growth, these solutions present some weaknesses like congestion and high latency for flows treatment. To improve our solutions, we propose in this paper a new Batch routing algorithm within CamCube server only topology network that overcomes these limits. Then, we compare our proposal with the existing shortest path approach. The obtained results show that our proposal outperforms its competitor in terms of packet loss and latency.
