    • 摘要: 软件定义网络和网络功能虚拟化能够有效解决大型网络难以管控、资源调度困难等问题。随着大规模卫星网络广泛应用,用户数量激增,对服务性能要求逐渐增加,这给网络管控和资源调度带来极大的负担,将软件定义网络的架构模型以及网络功能虚拟化等技术应用在大规模卫星互联网,可以有效解决目前存在的一些问题。提出基于SDN/NFV的新型卫星互联网架构,不同的卫星域可负责不同的功能,星间和域间可利用SDN和NVF进行有效协作,高效地利用网络资源,同时对其服务功能资源分配技术进行研究,优化VNF部署;提出基于资源感知的模拟退火算法,仿真结果表明此算法可以有效地降低服务功能链(SFC)数据流在传输时的端到端时延和带宽消耗,可以为用户提供更好的服务。

    • 摘要: The scope of the 5G network is not only limited to the enhancements in the form of the quality of service(QoS),but it also includes a wide range of services with various requirements.Besides this,many approaches and platforms are under the umbrella of 5G to achieve the goals of endto-end service provisioning.However,the management of multiple services over heterogeneous platforms is a complex task.Each platform and service have various requirements to be handled by domain experts.Still,if the next-generation network management is dependent on manual updates,it will become impossible to provide seamless service provisioning in runtime.Since the traffic for a particular type of service varies significantly over time,automatic provisioning of resources and orchestration in runtime need to be integrated.Besides,with the increase in the number of devices,amount,and variety of traffic,the management of resources with optimization becomes a challenging task.To this end,this manuscript provides a solution that automates the management and service provisioning through multiple platforms while assuring various aspects,including automation,resource management and service assurance.The solution consists of an intent-based system that automaticallymanages different orchestrators,and eliminates manual control by abstracting the complex configuration requirements into simple and generic contracts.The proposed systemconsiders handling the scalability of resources in runtime by usingMachine Learning(ML)to automate and optimize service resource utilization.

    • 摘要: Digital Twin(DT)is a pivotal application under the industrial digital transformation envisaged by the fourth industrial revolution(Industry 4.0).DT defines intelligent and real-time faithful reflections of physical entities such as industrial robots,thus allowing their remote control.Relying on the latest advances in Information and Communication Technologies(ICT),namely Network Function Virtualization(NFV)and Edge-computing,DT can be deployed as an on-demand service in the factories close proximity and offered leveraging radio access technologies.However,with the purpose of achieving the well-known scalability,flexibility,availability and performance guarantees benefits foreseen by the latest ICT,it is steadily required to experimentally profile and assess DT as a Service(DTaaS)solutions.Moreover,the dependencies between the resources claimed by the service and the relative demand and work loads require to be investigated.In this work,an Edge-based Digital Twin solution for remote control of robotic arms is deployed in an experimental testbed where,in compliance with the NFV paradigm,the service has been segmented in virtual network functions.Our research has primarily the objective to evaluate the entanglement among overall service performance and VNFs resource requirements,and the number of robots consuming the service varies.Experimental profiles show the most critical DT features to be the inverse kinematics and trajectory computations.Moreover,the same analysis has been carried out as a function of the industrial processes,namely based on the commands imposed on the robots,and particularly of their ion-level,resulting in a novel trade-off between computing and time resources requirements and trajectory guarantees.The derived results provide crucial insights for the design of network service scaling and resource orchestration fra-meworks dealing with DTaaS applications.Finally,we empirically prove LTE shortage to accommodate the minimum DT latency requirements.

    • 摘要: 基于MANO架构,能够完成网元的生命周期管理,但是缺乏对资源池做容量预测分析,难以保障网元的服务质量需求。文章提出了一种基于NFV的服务质量保障方法,即在现有MANO系统中加入服务质量管理功能。通过监控模块收集网元的链路拓扑信息,构建虚拟资源与物理资源的映射关联,一旦网元内部出现故障,能够做出自愈操作。
