Transition between network connections
A computing device may broadcast a first message via a wireless interface while operating according to a first network topology. After broadcasting the first message, the computing device may receive the first message via a wired interface. Based on receiving the first message via the wired interface, the computing device may broadcast a second message indicating a second network topology via the wireless interface. Based on receiving the first message via the wired interface, the computing device may operate according to the second network topology.
