Emerging network-attached resource disaggregation architecture requires ultra-low latency rack-scale communication. However, current hardware offloading (e.g., RDMA) and user-space (e.g., mTCP) communication schemes still rely on heavily layered protocol stacks which requires the translation between PCIe bus and network protocol, or complex connection/memory resource management within RNICs, inevitably bringing latency overhead.
