Abstract：
 The invention relates to a purely distributed data exchanging method based on push-pull combination, belonging to the technical field of data exchange in network, for a signal central server and each client-end node in the network, periodically and circularly carrying out data exchange, and completing the services of transmitting, receiving, and requesting a group of data packets and including the steps: the node establishes and updates its local list of data packets for data exchange; transmits its local list of data packets to the known neighbor node; establishes and updates a list of candidate neighbor nodes for which each data packet can provide the service; as the communication in a ¡°pull¡± mode is smooth, converts the mode of communication from the neighbor node to it from the original ¡°pull¡± mode to a ¡°push¡± mode; if the communication in the ¡°push¡± mode from it to the neighbor node is blocked, converts the mode of communication from the said ¡°push¡± mode to the ¡°pull¡± mode. The invention has the properties of good extendibility, error recovery, data interactivity, etc.
