Background technique

AllJoyn is a point-to-point communication framework between devices based on C/S architecture, which consists of BusDaemon (bus daemon) and terminal nodes. BusDaemon is responsible for message routing between terminal nodes, service discovery and other functions. The terminal node refers to the application program running on the device, which needs to connect to the BusDaemon after startup. BusDaemon can be seen as a bus (Bus) segment running on different devices. The BusDaemons of the devices are connected to form a bus of a connected point-to-point network system. Buses provide a fast, lightweight way for distributed systems to communicate sequences of messages. Its goal is to allow two applications to communicate without having to deal with the details of the underlying mechanisms. However, since AllJoyn uses an interface for local network connection, AllJoyn devices cannot directly connect to a remote server through the AllJoyn interface to obtain firmware upgrade information. It can be seen that there is currently a lack of a localized firmware upgrade method for AllJoyn devices in the AllJoyn network.
