摘要

AR/VR互动游戏、超高清直播、4K无线投影、超视界等新兴应用意味着对超低延迟、超高带宽无线传输的需求。遗留的内核TCP堆栈并不完全令人满意，因为它会在主机上引起CPU瓶颈。在本文中，我们提出无线RDMA (W-RDMA)，使无线网络中的RDMA能够解决无线主机上的CPU瓶颈问题。通过试验台实验验证了W-RDMA的可行性。进一步讨论了技术挑战和未来机遇。我们相信，这是实现RDMA无线传输的一个小而关键的步骤。

WIP: When RDMA Meets Wireless

The emerging applications including AR/VR inter-active gaming, ultra-high-definition live streaming, 4K wireless projection, Metaverse, etc. imply the demand for ultra-low latency and ultra-high bandwidth wireless transmission. The legacy kernel TCP stack is not fully satisfactory because it induces the CPU bottleneck on hosts. In this paper, we propose Wireless-RDMA (W-RDMA) that enables RDMA in wireless networks to tackle the CPU bottleneck issue on wireless hosts. The feasibility of W-RDMA is demonstrated through testbed experiments. Technical challenges and future opportunities are further discussed. We believe it is a small but crucial step for enabling RDMA for wireless transmission.
