“…Theoretically, it was proven that the BitTorrent would show a negative impact in its performance under the influence of SDN. However, it was contradicted when the experiments were conducted on a Ring topology [13], in which the BitTorrent outperformed even under the impact of the SDN controller. In order to confirm this behavior in a more general case, these experiments were re-conducted on a Mesh topology in this paper, which supported the theory and showed a negative impact in the performance of BitTorrent when it is used together with the SDN architecture.…”

“…This section elaborates the theory that formed basis for our research work. The theory is based on an assumption that the implementation of SDN on the BitTorrent application would show a negative impact on BitTorrent's performance [13]. The reason for this assumption is illustrated with the example as shown in Fig.…”

“…These two problems suggested that a negative impact could be obtained by this interaction between SDN and BitTorrent. An experiment was conducted [13] by emulating a Ring topology to observe the BitTorrent's behavior to verify the assumption made. The results obtained were beyond expectation, as they showed an enhancement in the BitTorrent's performance.…”

“…Therefore, as a link goes down, SDN has to do reactive routing according to the variations in the logical topology of the network. Thus, the outcome of the experiment reported in [13] became the motivation for this research work.…”

International audience– 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

Investigation on software‐defined networks’ reactive routing against BitTorrent

Technologies in software-defined networks (SDNs) introduce programmatic ways to reorganise the network logical topology. A possible practical usage of SDNs is reactive routing, where the logical topology is continuously evolving based on traffic statistics and policies. Usually, the SDNs controllers are considered transparent to the higher layers. It is expected that changes in logical topology may not affect applications. The goal is to study the impact of logical topology changes on BitTorrent, a popular peer-to-peer protocol in practice. This study focuses on BitTorrent, and the experimental results show that BitTorrent may produce the opposite effect to the one expected. The authors have run 32 BitTorrent clients in an emulated SDN ring topology and changed the virtual topology periodically by removing one link at the time from the ring. The experiments produced lower propagation when logical topology changed periodically than when it was static for BitTorrent traffic. For comparison, the same experiments were recreated using HTTP. For HTTP, slower propagation is obtained when logical topology changed than when it was static. Finally, the results are discussed and it has been concluded that high layer protocols need to be carefully studied, and in some cases adapted, before being deployed in SDNs.
