A Distributed Agent Network

Abstract

The invention discloses a distributed agent network, which includes a plurality of nodes, and all clients of each node play the role of server and relay at the same time, and each node in the network is equal; when a client in a node needs When accessing the intranet service in the target node, the node needs to find nearby adjacent nodes through libP2P and the network where it is located, and then discover other nodes through the guidance of the adjacent nodes. NAT is required between the node and the target node When penetration can only be directly connected, the other nodes and / or adjacent nodes can guide the node to make a hole with the target node; when the node and the target node are in a symmetric NAT that cannot be holed , using intermediate nodes as relays to forward data streams. The invention utilizes existing public resources to establish a P2P connection, and delegates an external network client request to an internal network server through a standard proxy protocol, so that access to internal network services becomes simple.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a distributed agent network. Background technique [0002] With the rapid increase in the number of computers connected to the Internet, IP address resources are increasingly stretched. In order to solve the problem of lack of IP addresses, NAT technology was created. [0003] NAT can not only solve the problem of insufficient IP addresses, but also effectively avoid attacks from outside the network, hide and protect computers inside the network. At the same time, it also poses a problem to the application of P2P such as end-to-end connection. Hosts in different LANs cannot be directly interconnected. Although some intranet services can be exposed to the external network by setting gateway port mapping and virtual hosts, not everyone has the right to configure the gateway of his local area network, and There are also certain security risks in directly exposing th...

AI Technical Summary

Problems solved by technology

However, whether it is reverse proxy or NAT hole punching, there must be an external network server in advance

[0005] Because of this, it becomes very cumbersome to interconnect hosts in two different intranets

Especially when you do not have permission to configure the gateway, you still need to go through a third-party server to establish a connection with the intranet, which invisibly increases security risks
