摘要：
下一代移动核心网需要具备可扩展性，并能高效利用可能包含边缘服务器在内的异构裸金属资源。为此，基于微服务的解决方案正日益受到关注，该方案将控制面流程解构为基本构建模块。本文提出一个优化框架，实现大规模微服务图在异构裸金属部署上的划分与映射，同时最小化服务器之间的总网络流量。文中还提供了一种高效的启发式策略来求解该优化问题。仿真结果表明，在所提框架下，基于微服务的核心网能够在异构裸金属部署中持续支撑所请求的负载，即使替代架构失效时也是如此。此外，与当前核心网架构相比，本框架确保了控制面相关网络流量的整体降低。
英文摘要：
Next-generation mobile core networks are required to be scalable and capable of efficiently utilizing heterogeneous bare metal resources that may include edge servers. To this end, microservice-based solutions where control plane procedures are deconstructed in their fundamental building blocks are gaining momentum. This letter proposes an optimization framework delivering the partitioning and mapping of large-scale microservice graphs onto heterogeneous bare metal deployments while minimizing the total network traffic among servers. An efficient heuristic strategy for solving the optimization problem is also provided. Simulation results show that, with the proposed framework, a microservice-based core can consistently support the requested load in heterogeneous bare metal deployments even when alternative architecture fails. Besides, our framework ensures an overall reduction in the control plane-related network traffic if compared to current core architectures.
