Abstract
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.
