The present invention provides a network architecture method, and traffic distribution method and related device, comprising: in a wireless network, splitting the functions performed by a PGW, an SGW, and an MME; according to the traffic type of said functions, deploying the split functions in a centralized control network element, a data rule matching entity, a distribution entity, a network address translator, a functional node network, and a broadcast node; it can be seen that decoupling the functions in an MME, PGW, and SGW in a wireless network, splitting the functions from their original physical entities, and deploying the functions to functional nodes (FN) in a functional node network (FNN) allows for the implementation of SDN architecture of a wireless network. An SNC determines the operating states of the FNs by means of monitoring the traffic loads of the FNs in the FNN, and distributes traffic according to different operating states, such that the traffic distribution can be adjusted dynamically according to changes in FN operating state. |
