论文摘要
多访问边缘计算（MEC）将为移动4G/5G网络用户启用上下文感知服务。 MEC应用程序开发人员需要工具来帮助其应用程序的设计和性能评估。在部署的早期阶段，他们应该能够评估设计选择的性能影响 - 例如，由于计算，通信和服务消耗的相互作用，可以预期什么往返延迟。当存在该应用程序的原型时，需要对其进行测试，以在可控条件下实时测量关键性能指标。在本文中，我们提出了一个开源框架，该框架允许开发人员完成上述所有操作。我们的框架基于SIMU5G，基于Omnet ++的5G（Newradio）和4G（LTE）移动网络的模拟器。它包括MEC实体的模型（即MEC编排，MEC主机等），并为应用程序端点提供了一个符合标准的固定界面。此外，它可以与外部应用程序接口，也可以实时运行。因此，人们可以将其用作摇篮来实时运行MEC应用程序，并根据基础基础模拟无线电访问网络生成的信息在4G/5G数据包传输和MEC服务下。我们描述了我们的框架，并介绍了模仿MEC的5G场景的用例。
Multi-access Edge Computing (MEC) will enable context-aware services for users of mobile 4G/5G networks. MEC application developers need tools to aid the design and the performance evaluation of their apps. During the early stages of deployment, they should be able to evaluate the performance impact of design choices - e.g., what round-trip delay can be expected due to the interplay of computation, communication and service consumption. When a prototype of the app exists, it needs to be tested it live, under controllable conditions, to measure key performance indicators. In this paper, we present an open-source framework that allows developers to do all the above. Our framework is based on Simu5G, the OMNeT++-based simulator of 5G (NewRadio) and 4G (LTE) mobile networks. It includes models of MEC entities (i.e., MEC orchestrator, MEC host, etc.) and provides a standard-compliant RESTful interface towards application endpoints. Moreover, it can interface with external applications, and can also run in real time. Therefore, one can use it as a cradle to run a MEC app live, having underneath both 4G/5G data packet transport and MEC services based on information generated by the underlying emulated radio access network. We describe our framework and present a use-case of an emulated MEC-enabled 5G scenario.
