| 17 | 17 | The client-level component of the testbed exists entirely on-board the client and is responsible for both switching the active physical interface and maintaining all client sockets during such a handover event. To maintain active sockets, a default virtual network interface (VNI) is installed on the client. All applications send and receive packets through this VNI, and by nature of a virtual interface, it is not impacted by physical interface states. The client is also equipped with OVSs and its own FL OF controller. This controller is responsible for routing packets from the VNI's OVS, through the client-level OVS network, and then to the physical interface of choice as determined by a handover decision. |
