The basis of this paper is grounded upon the theoretical assumption, which states that the integration of BitTorrent with Software-defined Networks (SDNs) will degrade the performance of BitTorrent, instead of improving it. This was further evaluated by emulating this experiment on a Ring topology to verify the results. The experimental results, however, showed an unexpected behavior wherein BitTorrent outperformed under a SDN. This objective of this paper is to re-evaluate the behavior of BitTorrent in a Mesh topology instead. We have run 12 BitTorrent clients in an emulated SDN Mesh topology using Mininet and varied the virtual topology periodically by taking one link down at a time from the topology. The experimental results show when the logical topology changed periodically the performance is worse than when the topology is static for BitTorrent.
