Abstract: A method and device for forwarding an interest packet based on a probability tree in an information network. By introducing a probability tree, the process of forwarding an interest packet is finally changed into a selection process: starting from a root node of the probability tree, selecting child nodes of a current node according to the probability of each child node of the current node, and stopping selecting until the selected child node is a leaf node. Moreover, the introduced probability tree provides a good carrier for machine learning. By considering the selection process as an optimization problem, the selection process can be converged to be approximate to an optimal state using online machine learning, and moreover, the probability of each node in the probability tree can be adjusted according to changes in network conditions, so that the forwarding method and device have strong adaptability to the network changes, thereby improving self-adaptability.
