Compute first networking (CFN) is a latest distributed framework that intelligently allocates computing resources for edge computing according to computing load and network status. It requires real-time visibility of available statuses of local or remote computing resources. To the best of our knowledge, this paper is the first to propose a centralized fault-detection protocol called CFN-Watchdog to well meet this CFN requirement and timely recycle resources occupied by faults. We then theoretically analyze the impact of various parameters (e.g., detection thresholds, task processing time, and network delay) on the Watchdog performance. Extensive simulations verify the effectiveness of our proposed protocol and the accuracy of our theoretical model. This study is very helpful to optimize parameter configurations and better design fault-detection protocols for edge computing.

一种用于边缘计算的新型 CFN-Watchdog 协议

计算优先网络(CFN)是最新的分布式框架,可以根据计算负载和网络状态为边缘计算智能分配计算资源。它需要实时查看本地或远程计算资源的可用状态。据我们所知,本文首次提出了一种称为 CFN-Watchdog 的集中式故障检测协议,以很好地满足这种 CFN 要求并及时回收故障占用的资源。然后我们从理论上分析了各种参数(例如,检测阈值、任务处理时间和网络延迟)对看门狗性能的影响。广泛的模拟验证了我们提出的协议的有效性和我们理论模型的准确性。
