DISTRIBUTED SYSTEM NAT TRAVERSAL METHOD, APPARATUS, AND DEVICE, AND STORAGE MEDIUM

摘要

Embodiments of the present application relate to the field of blockchains, and relates to a distributed system NAT traversal method, apparatus, and device, and a storage medium. The method comprises: when a first node accesses a P2P network, establish a communication connection with a public network node in the P2P network, obtain the node information of a node list of the public network node, and update a local node list; when the first node requests a storage resource, obtain, by means of an overlay network transmission protocol of the P2P network, the information of a nearest second node that may provide the storage resource for the first node; according to the obtained information of the second node, the first node establishes a communication connection with the second node. In the present application, a central STUN/TURN server does not need to be carried, and when peer nodes cannot perform direct communication, a node close to a target node is requested to assist hole punching to realize traversal.
