Novel Optimized SDN Routing Scheme in CamCube Server Only Data Center Networks

Actually the important growth of intra datacenter traffic pushes researchers to optimize the resource allocation functions, mainly routing. In this work, we consider the problem of path calculation within a server only data center topology called “Camcube”. The routing function for Camcube, is based on link state protocol implemented in a distributed control plane. We rebuild the Camcube topology within a Software Defined Networking (SDN) scheme. The control plan is logically centralized thanks to a controller such as the Open Networking Operating System (ONOS). Extensive experimentation results have been presented with the shortest path algorithm showing the latency and packet loss metrics with different traffic profiles. This work is a first step toward a complete study of the resource allocation problem for CamCube based intra-datacenters.
