摘要
6G系统将实现面向千行百业的多样化和定制化的按需网络服务。端到端网络切片可为用户提供按需灵活的服务保障。然而,现有的基于网络切片的网络服务编排与控制技术存在人工参与度高、配置复杂度高及运维成本高等问题。因此,需要一种解决方案应对这些挑战。意图驱动网络具有灵活可重构和自适应策略优化等特性,可提升用户端到端的服务体验。提出了意图驱动端到端网络切片编排与控制系统架构,该系统由业务应用层、意图使能层和基础设施层构成;在此基础上,设计了意图解析模块、编排与控制模块;并从用户满意度和系统智能性等角度构建效用评估模型,通过仿真评估系统效用。
The 6G system will realize diversified and customized on-demand network services for thousands of in-dustries.End-to-end network slicing can provide users with on-demand and flexible service guarantees.However,the existing network service orchestration and control based on network slicing has problems such as high manual par-ticipation,high configuration complexity,and high operation and maintenance cost.Therefore,a solution is urgently needed to meet these challenges.Intent-driven network has the characteristics of flexible reconfiguration and adaptive policy optimization,which can improve the user’s end-to-end service experience.An intent-driven end-to-end network slicing orchestration and control system architecture was proposed,which consisted of business application layer,intent-enabled layer and infrastructure layer.On this basis,the intent parsing module,orchestration and control module were designed.Furthermore,a utility evaluation model was constructed from the perspectives of user satisfaction and system intelligence,and system utility was evaluated through simulation.
