A Survey of Building Efficient P2P Streaming Systems in SDN
Jianwei Zhang, Chunling Yang, Huiling Shi, Lu Wang · 2017
Currently, the contradiction between the rapid growth of network traffic and the limited network resource is plaguing network operators and Internet users. In this paper, we conduct a survey on how to build efficient streaming systems in edge network under SDN (software defined networking) architecture and on how to manage the large traffic in core network caused by file transferring and media streaming applications. We categorize and discuss related studies as P2P (peer-to-peer) optimization at application layer, traffic engineering and QoS routing at network layer, and the most important cross-layer studies, which consist of P2P research in transport and network layers and SDN group applications. Combining the previous research in this field, we propose three potential directions for future research. For each direction, we present a conceptual strategy and its possible implementation in OpenFlow, which can capture the essential features of the SDN architecture and the P2P streaming system.
