Edge gateway message routing coordination method and system based on distributed network Technical Field The present invention relates to the field of data transmission technologies, and in particular, to a method and a system for edge gateway message routing coordination based on a distributed network. Background When the mobile terminal (such as a mobile phone terminal) accesses the storage data on the network additional storage device (such as NAS device), the conventional mode needs to register the mobile phone terminal and the NAS device to a central gateway respectively, and then uses the central gateway as a transit node to inquire the node address currently registered by the opposite party. Therefore, the central gateway needs to maintain all node registration information in the whole network and instruct how to establish connection between the mobile phone end and the NAS device. However, the "central gateway" in the current architecture has a single point of failure risk, which can lead to a full network crash once the system is down. In addition, according to the data interaction architecture based on the central gateway, other nodes in butt joint with the central gateway need to forward data through the central gateway, so that even if two devices are in the same intranet, when the two devices perform data interaction, the data forwarding is required to be performed at the central node, and direct interaction of the two devices cannot be performed directly, and message delay and extra performance cost are increased. In addition, when the central gateway accesses to the mass equipment, the read-write pressure of the central gateway can also cause performance bottleneck of the system.
