AI总结:

本文提出智能路由即服务(iRaaS)架构,作为知识定义网络的应用层认知路由框架,支持路由逻辑定制并可将训练模型的启发式参数纳入度量计算,通过可靠性启发式与SPF、DUAL算法结合验证其可行性。

摘要:

第六代自组织网络(6G-SON)的范畴将其前代的能力推进到敏捷性、灵活性和适应性。按需覆盖网络技术在应对企业、服务提供商和数据中心网络日益增长的复杂性与规模方面已表现出显著的成熟度。软件定义网络范式近来提供了模型驱动的可编程性,通过自动化与编排将网络管理复杂性降至最低。然而,利用机器学习驱动的网络优化,即知识定义网络(KDN),仍然是网络软件化研究界关注的领域。在本文中,我们提出智能路由即服务(iRaaS)架构,作为面向KDN的应用层认知路由框架。iRaaS提供路由逻辑定制(即定制度量函数和路径发现算法),并提供将训练模型中的启发式参数纳入度量计算的选项。iRaaS位于KDN协议栈中知识平面之上的应用平面,从而提供与现有网络基础设施的平台无关和供应商无关的耦合。本文通过将可靠性作为标准路径发现算法(例如最短路径优先(SPF)和扩散更新算法(DUAL))的启发式参数,并结合架构规范,涵盖iRaaS的适用范围。我们通过概念验证部署验证了该方法。

英文摘要:

The scope of the Sixth-Generation Self-Organized Networks (6G-SON) advances its predecessor's capability towards agility, flexibility, and adaptability. On-demand overlay networking technologies have shown a prominent maturity while coping with the rising complexity and scale of enterprise, service provider, and data centre networks. The Software-Defined Networking paradigm has recently offered Model Driven Programmability, minimizing network management complexity through automation and orchestration. However, leveraging Machine Learning-driven network optimization, a.k.a. Knowledge-Defined Networking (KDN), has still been a domain of interest for the Network Softwarization research community. In this article, we propose Intelligent Routing as a Service (iRaaS) architecture as an application layer cognitive routing framework for KDNs. iRaaS offers routing logic customization (i.e., customizing metric function and path-finding algorithm) and provides an option to include heuristic parameters from trained models as a part of the metric calculation. iRaaS sits on the application plane above the knowledge plane in a KDN stack, thus providing platform- and vendor-agnostic coupling with existing network infrastructures. This article covers the scope of iRaaS by using reliability as a heuristic for standard path-discovery algorithms, e.g., Shortest Path First (SPF) and Diffusion Update algorithm (DUAL), along with the architectural specification. We validate our approach through a Proof-of-Concept deployment.
