标题： DMSA: A Decentralized Microservice Architecture for Edge Networks

摘要： 分散的节点位置和边缘网络的复杂拓扑结构，加上复杂的动态微服务依赖关系，使得传统的集中式微服务架构（MSA）不再适用。 在本文中，我们提出了一种去中心化微服务架构（DMSA），将调度功能从控制平面转移到边缘节点。 DMSA 重新设计并实现了微服务发现、监控和调度的三个核心模块，以分别实现对实例部署的精确感知、低监控开销和测量误差以及准确的动态调度。 特别是，DMSA 定制了一个微服务调度方案，利用多端口监听和零拷贝转发来保证高效的数据转发。 此外，提出了一种动态加权多级负载均衡算法，考虑可靠性、优先级和响应延迟来动态调整调度。 最后，我们为 DMSA 实现了一个物理验证平台。 大量实证结果表明，与最先进的和传统的调度方案相比，DMSA 能有效应对链路故障和网络波动，分别将服务响应延迟和执行成功率提高了大约$60\% \sim 75\%$和$10\%\sim15\%$。 显示英文摘要

摘要： The dispersed node locations and complex topologies of edge networks, combined with intricate dynamic microservice dependencies, render traditional centralized microservice architectures (MSAs) unsuitable. In this paper, we propose a decentralized microservice architecture (DMSA), which delegates scheduling functions from the control plane to edge nodes. DMSA redesigns and implements three core modules of microservice discovery, monitoring, and scheduling for edge networks to achieve precise awareness of instance deployments, low monitoring overhead and measurement errors, and accurate dynamic scheduling, respectively. Particularly, DMSA has customized a microservice scheduling scheme that leverages multi-port listening and zero-copy forwarding to guarantee high data forwarding efficiency. Moreover, a dynamic weighted multi-level load balancing algorithm is proposed to adjust scheduling dynamically with consideration of reliability, priority, and response delay. Finally, we have implemented a physical verification platform for DMSA. Extensive empirical results demonstrate that compared to state-of-the-art and traditional scheduling schemes, DMSA effectively counteracts link failures and network fluctuations, improving the service response delay and execution success rate by approximately $60\% \sim 75\%$ and $10\%\sim15\%$, respectively.
