M-CRP: Novel Multicast SDN Based Routing Scheme in CamCube Server-Only Datacenter

Multicast routing provides an efficient way to support Data Center (DC) applications (e.g., replication process of MapReduce jobs, Market data and stock notification apps, and IPTV servers) as it conserves network bandwidth and reduces server load. However, a good use of multicast within the traditional DC networks requires higher performance and capacity from the network devices such as the tables capacity of access and aggregation switches. In this paper, we propose and evaluate a novel multicast routing scheme, named M-CRP, in a promising CamCube Server-Only DC architecture while considering the Software Defined Network (SDN) paradigm. To do that, first we formulate the problem as a lexicographic multi objective optimization problem. Then, we propose new optimized SDN application, M-CRP, based on Branch and Cut and monitors the CamCube DC infrastructure with OpenFlow southbound protocol. We evaluate the performance of our proposal using experimental platform built with ONOS controller and Mininet. The obtained results show that M-CRP is better in terms of packet loss, latency and jitter compared with traditional shortest path multicast routing protocol.
