中文摘要：

分析了超高吞吐率Wi-Fi在无线网络密集部署情况下的典型应用及其性能需求,提出超高吞吐率Wi-Fi基于软件定义网络的网络架构、无线网络侧虚拟化等新型机制。实验结果表明：超高吞吐率Wi-Fi能有效提升网络吞吐率,但与802.11a/n并存将导致网络性能变差,结合SDN、NFV技术可以实现延展性和抗干扰性的提高,在吞吐率性能上获得更大的提升,保障超高吞吐率Wi-Fi在未来密集部署的无线网络中发挥重要作用。

英文摘要：

The paper analyzes, in the case of intensive-deployed wireless network, the typical applications and performance requirements of Wi-Fi VHT, and proposes its network architecture based on SDN, wireless network virtualization mechanisms. The experimental results show that while VHT Wi-Fi can effectively improve the network throughput, the coexistence of VHT Wi-Fi and 802.11a/n will lead to poor network performance. Combination of SDN and NFV, however, can achieve scalability and interference immunity, improve considerably the throughput performance and ensure the role of the VHT Wi-Fi in future dense wireless network deployments.
