论文摘要
多访问边缘计算（MEC）将允许实施到目前为止一直不可行的低延迟服务。欧洲电信标准研究所（ETSI）和第三代合作伙伴项目（3GPP）正在努力实现5G网络中MEC的标准化，以及将用户流量路由将用户流量路由到当地网络中的应用程序的相应解决方案。然而，既没有将应用程序从核心转移到MEC主机，也没有从一个MEC主机到另一个确保服务连续性的实际实现。在本文中，我们提出了一个基于软件定义的网络（SDN）的解决方案，以创建一个新的IP锚点的实例，以动态重定向用户设备（UE）流量到新的物理位置（例如边缘基础结构）。我们还提出了一种新的方法，该方法利用SDN在IP锚点的新实例中复制连接的先前上下文，从而保证了会话和服务连续性（SSC），并将其与替代状态复制策略进行比较。该方法可用于在4G或5G网络中实现边缘服务。
Multi-Access Edge Computing (MEC) will allow implementing low-latency services that have been unfeasible so far. The European Telecommunications Standards Institute (ETSI) and the 3rd Generation Partnership Project (3GPP) are working towards the standardization of MEC in 5G networks and the corresponding solutions for routing user traffic to applications in local area networks. Nevertheless, there are neither practical implementations for dynamically relocating applications from the core to a MEC host nor from one MEC host to another ensuring service continuity. In this paper we propose a solution based on Software-Defined Networking (SDN) to create a new instance of the IP anchor point to dynamically redirect User Equipment (UE) traffic to a new physical location (e.g. an edge infrastructure). We also present a novel approach that leverages SDN to replicate the previous context of the connection in the new instance of the IP anchor point, thus guaranteeing Session and Service Continuity (SSC), and compare it with alternative state replication strategies. This approach can be used to implement edge services in 4G or 5G networks.
