Abstract

The invention relates to a network data traffic distribution method and system in the technical field of data communication, and the method comprises the following steps: building a VPN tunnel, and configuring a virtual network card for intercepting and forwarding an event data traffic packet; registering a monitoring event in a C language application layer of the VPN tunnel, monitoring an event data traffic packet sent by the virtual network card based on the monitoring event, and analyzing the event data traffic packet to extract a protocol field; determining a protocol analysis module based on the protocol field, and extracting a target IP address in the event data traffic packet through the protocol analysis module; and determining a system network path to which the network session needs to be bound based on the target IP address, and distributing the event data traffic packet to a cellular data network or a Wi-Fi network of the IoT device based on the system network path bound with the network session, thereby solving the problem that the mobile terminal cannot realize bidirectional parallel use of the IoT device and the Internet.
