当前的物联网设备支持多宿主，以提高弹性和性能。网络交换有助于分担负载并保持通信畅通。因此，如果需要相互切换(即垂直切换)，则必须研究这些异类接口的行为。特别研究了基于软件定义网络(SDN)环境下物联网设备的切换时间问题。以树莓PIS为实验平台，发现切换时间因源/目的接口和切换方向的不同而有很大差异，特别是与仿真结果相比有较大差异。
Current IoT devices support multi-homing to improve resilience and performance. Network switching helps to distribute the load and keep communication going. Therefore, it is essential to investigate how these heterogeneous interfaces behave if it is necessary to switch from one another (i.e., vertical handover). In particular, this paper addresses the handoff time of IoT devices in Software-Defined Network (SDN) based environments. Using Raspberry Pis as a testbed, we found out that there is a significant difference in handoff time depending on the source/destination interface and the switching direction, especially compared to simulation results.
