Rapid Advancements in P2P Streaming Technologies Pave Way for Secure and Reliable Communication

Strategic Insights

— 1 min read

Recent research conducted by the King Abdulaziz University in Jeddah, Saudi Arabia, has highlighted the potential of combining software-defined networking (SDN) and blockchain technologies to improve peer-to-peer (P2P) streaming. Despite the advancements in P2P streaming, challenges persist, including dynamic topology management, high latency, security vulnerabilities, and unfair resource sharing. The study proposes a distributed SDN (DSDN) architecture enhanced with blockchain support to provide secure, scalable, and reliable P2P video streaming.

Key Takeaways:

  • The research identified research gaps in the literature through critical analysis and systematically compared traditional P2P, SDN-enhanced, and hybrid architectures across six performance metrics: latency, throughput, packet loss, authentication accuracy, packet delivery ratio, and control overhead.
  • Simulations with 200 peers demonstrated that the proposed hybrid SDN-blockchain framework achieved a latency of 140 ms, a throughput of 340 Mbps, an authentication accuracy of 98%, a packet delivery ratio of 97.8%, a packet loss ratio of 2.2%, and a control overhead of 9.3%.
  • The proposed framework outperformed state-of-the-art solutions such as NodeMaps, the reinforcement learning-based routing framework (RL-RF), and content delivery networks-P2P networks (CDN-P2P).
  • The study established a scalable and attack-resilient foundation for next-generation P2P streaming.
  • The research was conducted by a team of researchers from King Abdulaziz University, including Aisha Mohmmed Alshiky, Maher Ali Khemakhem, Fathy Eassa, and Ahmed Alzahrani.

Statistics:

  • Latency: 140 ms
  • Throughput: 340 Mbps
  • Authentication accuracy: 98%
  • Packet delivery ratio: 97.8%
  • Packet loss ratio: 2.2%
  • Control overhead: 9.3%
  • Number of peers: 200
