The invention discloses an asynchronous distributed deep learning training method, device and system. The method is applied to a computing node k, the computing node performs the forward propagation through the local model parameters and the local data to obtain the loss values, then the gradient updating is obtained via the backward propagation, and only the values with larger information amount in the gradient updating vectors are sent by using the sparse function, so that the communication traffic from the computing node to the parameter server is effectively reduced. On the basic concepts of the asynchronous random gradient descent and a parameter server, the gradient of the computing node is returned via the parameter server, the communication compression is carried out, the compression rate of the communication is effectively guaranteed. The compression rate of communication is continuously increased along with the continuous training, and a better compression effect and a higher communication speed can be achieved.

This invention discloses a random connective method of movable IP terminal without collocation. When the movable terminal is linked to the acting node of other place, send the movable terminal registering information to the acting node of other place, the agent of other place receives the IP address; the agent of other place receives the movable terminal registering information and sends movable terminal adding information to all nodes, and the information includes IP address of the movable IP terminal, interface IP network address of the agent; each network node sets information form of movable users and stores the information in the information form; according to the corresponding relation between the IP address of the movable IP terminal in the information form and the interface IP address, establish the direct communication channel from the access terminal to the movable IP terminal. In this way, it avoids the flux centralization between the home agent and abroad agent and improves the utility efficiency and performance of the network.
