The fifth generation (5G) of mobile networks is seen as a key enabler to support the introduction of digital technologies in multiple sectors, empowering different verticals and enabling new business models. Thanks to native capabilities of 5G networks, especially network slicing, edge computing and multi-tenancy, highly integrated telecom infrastructures with end-to-end flexibility will be realized to lower the barriers for creating 5G-ready applications that are able to satisfy business and user necessities. In this context, the MATILDA Project has established a holistic framework that unifies the development, deployment and operation for this new kind of applications. Since Edge Computing is not natively supported by 4G, in order to anticipate the technological improvements foreseen with the advent of 5G, as well as to smoothen the transition to the new technology, this paper describes the design of the end-point between the mobile and edge environments that has been integrated in the MATILDA telecom layer platform. Such end-point, designed in a Virtual Network Function (VNF), allows intercepting and forwarding data and control traffic towards external Data Networks. Instances of this VNF can be horizontally scaled according to a decision policy, which determines the minimum number of instances required for the current load. Results show that the latency ascribable to the VNF processing is sufficiently low to satisfy the delay budget for all 5G use-cases up to 10 ms and that a QCI-based decision policy allows scaling with the traffic load, while still fulfilling the performance requirements of each application.

第五代（5G）移动网络被视为支持在多个领域引入数字技术，支持不同垂直领域并启用新业务模型的关键推动力。得益于5G网络的固有功能，尤其是网络切片，边缘计算和多租户，将实现具有端到端灵活性的高度集成的电信基础架构，从而降低创建能够满足业务和业务需求的支持5G的应用程序的障碍。用户必需品。在这种情况下，MATILDA项目已经建立了一个整体框架，统一了这种新型应用程序的开发，部署和操作。由于Edge Computing不受4G的本地支持，因此，为了预见5G的到来将带来技术上的进步，为了简化向新技术的过渡，本文描述了已集成在MATILDA电信层平台中的移动和边缘环境之间的端点设计。在虚拟网络功能（VNF）中设计的这种端点允许拦截和转发数据并控制流向外部数据网络的流量。可以根据决策策略水平缩放此VNF的实例，该决策策略确定当前负载所需的最少实例数。结果表明，归因于VNF处理的等待时间足够短，不足以满足所有5G用例长达10 ms的延迟预算，并且基于QCI的决策策略允许随流量负载扩展，同时仍满足以下性能要求每个应用程序。本文介绍了已集成在MATILDA电信层平台中的移动环境和边缘环境之间的端点设计。在虚拟网络功能（VNF）中设计的这种端点允许拦截和转发数据并控制流向外部数据网络的流量。可以根据决策策略水平缩放此VNF的实例，该决策策略确定当前负载所需的最少实例数。结果表明，归因于VNF处理的等待时间足够短，不足以满足所有5G用例长达10 ms的延迟预算，并且基于QCI的决策策略允许随流量负载扩展，同时仍满足以下性能要求每个应用程序。本文介绍了已集成在MATILDA电信层平台中的移动环境和边缘环境之间的端点设计。在虚拟网络功能（VNF）中设计的这种端点允许拦截和转发数据并控制流向外部数据网络的流量。可以根据决策策略水平缩放此VNF的实例，该决策策略确定当前负载所需的最少实例数。结果表明，归因于VNF处理的等待时间足够短，不足以满足所有5G用例长达10 ms的延迟预算，并且基于QCI的决策策略允许随流量负载扩展，同时仍满足以下性能要求每个应用程序。
