Summary:
|
Remote Direct Memory Access (RDMA), with zero-copy and low latency, can enhance the transmission efficiency, which already serve as a core supporting technology stack for high-performance computing and data centres. RDMA imposes a critical requirement for lossless network transmission due to its fundamental design and operational characteristics. Even minimal packet loss severely degrades its performance, undermining its core advantages of ultra-low latency and high throughput. It is usually running in dedicated links, e.g. fibre optic connections. However, in some situations, such as wide-area computing power interconnection, and efficient disaster recovery system for remote databases, high-quality connection cannot be guaranteed, and the network packet loss is difficult to avoid. Therefore, enabling RDMA over wide-area networks remains a current research challenge and open question.
As an emerging technology, Information-centric networking (ICN) introduces new features, such as name-based routing, in-network caching, mobility management, which can support the performance targets of networks beyond IMT-2020 [ITU-T Y.3033]. And its native capabilities about in-network caching, instant packet re-addressing, dynamical path selection and preference-driven transmission can alleviate the packet loss, avoid the network congestion and aggregate links, which may support RDMA running over a ICN network with high transmitting speed.
Consequently, this draft Recommendation specifies the framework and capabilities enhancement of ICN for supporting RDMA, which can meet the requirement of low-delay, lossless transporting, and high-throughput transmission.
