The embodiment of the invention provides a message forwarding and buffering method and apparatus. The method comprises: a request packet is obtained; hop counts of a current request node and all adjacent nodes are obtained and a first node set is determined; a node busy degree of a first adjacent node, a node buffer amount of the first adjacent node and a path time delay from the current request node to the first adjacent node are obtained, and a node buffer value of the first adjacent node is determined according to the above-mentioned information; and on the basis of the node buffer value, a shapley value corresponding to the first node set is determined based on a shapley value formula; a forwarding proportion of each adjacent node in the first node set is allocated correspondingly based on a shapley value index in the shapley value, each adjacent node forwards a request packet and a forwarding path is recorded; and a data packet that is returned along an opposite direction of the forwarding path is received and a buffer node of a buffered data packet is determined based on the buffer probability of the node. Therefore, the message forwarding and buffering costs are saved and balanced forwarding is realized.
