    2222The mobility testbed includes many OVSBs within the network. As discussed previously, the network-level OVSBs connect to the network-level FL controller / DHCP server. These OVSBs are used in the detection of client migrations and the routing of client packets into and out of the testbed. Specifically, the OVSBs on the testbed edge detect client migration by intercepting DHCP request packets, while the OVSBs in the core direct the flow of client packets from the testbed root to the client on the testbed edge.

    2525Each network-level node with OVSBs also uses OVS patch ports (OVSPPs). To ensure proper routing of packets destined for an IP not routable by a foreign network, OVSPPs are used to connect the external and internal facing OVSBs installed on the gateways/APs. This allows independent subnets to operate within the testbed. The OVSPPs, combined with flows that utilize these OVSPPs, force client packets to bypass Linux routing on each hop, thus supporting cross-subnet compatibility upon migration from the home network.
