Abstract: 
The coverage of network resources is increasingly extensive, and computing resources have likewise gradually become fundamental infrastructures, providing ubiquitous computing services. However, in wide area networks (WANs), the underlying network and computing resources are not closely investigated or co-designed, and there are still problems reflected in slow computing service scheduling, inflexible data distribution, and inefficient data transmission. This paper proposes the architectural design of a computing-aware network (CAN), with the core contribution of introducing the awareness plane to collect, manage, and synthesize computing and network information. In this way, the awareness plane, control plane, and data plane are formed as a closed-loop control system to improve the overall system’s awareness capability, decision-making capability, and data forwarding functionality. To enable the CAN architecture, three key technologies are proposed as follows: computing-aware traffic steering (CATS), elastic broadcast, and wide-area high-throughput transmission. The paper takes artificial intelligence (AI) model training, inference, and offline parameter transmission as examples to show the applicability of CAN and identifies some future research directions.

摘要:网络资源的覆盖范围日益广泛,算力资源也逐渐成为能够提供泛在计算服务的基础设施。然而,在广域网络,底层网络和计算资源缺乏密切的研究或协同设计,仍然存在计算服务调度缓慢、数据分发不灵活、数据传输效率低等问题。本文提出算力感知网络(CAN)的系统架构设计,其核心贡献在于引入感知平面来收集、管理并综合计算和网络的信息。这样,感知平面、控制平面和数据平面组成一个闭环控制系统,增强了整个系统的感知能力、决策能力和数据转发功能。为了使能CAN系统,本文提出三项关键技术:算力路由、弹性广播和广域高吞吐传输。本文以人工智能(AI)模型训练、推理和离线参数传输为例,展示CAN的适用性,并指出未来的一些研究方向。
