论文摘要
考虑到需要可靠的网络体系结构以应对5G网络必不可少的需求，3GPP引入了一种以5G服务的求职技术（5G-SBA）。同时，通过将应用程序托管从集中式数据中心带到网络边缘，更接近消费者和应用程序生成的数据，多访问边缘计算（MEC）与SBA相结合为最终用户提供了更好的体验。 3GPP和ETSI提案都提供了许多好处，尤其是提供高度可定制服务的能力。然而，与容忍标准虚拟化技术（虚拟机（VM）和服务器）托管的大型数据中心相比，MEC节点的特征是较低的计算资源，因此基于轻量级微服务应用程序的首次亮相。由当前基于微服务的应用程序缺乏支持用户运动的动机，并假设所有这些问题都在服务功能链（SFC）迁移的范围内，我们旨在引入，解释和评估多样化的SFC迁移模式。获得的结果表明，没有明确的征服者，但是选择正确的SFC迁移模式取决于用户的计算，应用程序的要求和MEC节点的资源。
Given the indispensable need for a reliable network architecture to cope with 5G networks, 3GPP introduced a covet technology dubbed 5G Service Based Architecture (5G-SBA). Meanwhile, Multi-access Edge Computing (MEC) combined with SBA conveys a better experience to end-users by bringing application hosting from centralized data centers down to the network edge, closer to consumers and the data generated by applications. Both the 3GPP and the ETSI proposals offered numerous benefits, particularly the ability to deliver highly customizable services. Nevertheless, compared to large datacenters that tolerate the hosting of standard virtualization technologies (Virtual Machines (VMs) and servers), MEC nodes are characterized by lower computational resources, thus the debut of lightweight micro-service based applications. Motivated by the deficiency of current micro-services-based applications to support users'mobility and assuming that all these issues are under the umbrella of Service Function Chain (SFC) migrations, we aim to introduce, explain and evaluate diverse SFC migration patterns. The obtained results demonstrate that there is no clear vanquisher, but selecting the right SFC migration pattern depends on users'motion, applications'requirements, and MEC nodes'resources.
