Abstract

The invention belongs to the field of communication, and discloses a peer-to-peer network and a node communication method and device thereof. The method comprises the steps: a source node searches a first node according to the address information of a to-be-connected target node; the source node sends a request for searching a target node to the first node; the source node receives a second node returned by the first node; if the second node is not the target node, the source node sends a request for searching the target node to the second node, and receives a third node returned by the second node according to the request until the returned node is the target node; and the source node communicates with the target node through the returned node. By means of the proxy node, when a communication link is blocked, the source node can establish point-to-point communication connection with the target node on the basis of not destroying an original security framework, and the security of the node is improved.

Description

technical field [0001] The present application belongs to the communication field, and in particular relates to a peer-to-peer network and its node communication method and device. Background technique [0002] Peer-to-peer (P2P for short), also known as peer-to-peer network, is an Internet system that has no central server and relies on user groups (peers) to exchange information. A decentralized network without a central server can be realized through a peer-to-peer network, which has been widely used in the blockchain field. [0003] However, between nodes across network domains, that is, between nodes across local area networks, due to equipment security requirements, security devices are usually installed between nodes, and nodes across network domains usually cannot directly establish a point-to-point network. In some cases, if the staff makes special settings for security devices, such as special settings for security devices, including gatekeepers and firewalls, the...
