Abstract

This application provides a data sending method, device, and a method and system for establishing a P2P connection, wherein the data sending method includes: S1: for n 1 The first access request packet establishes a queue containing m file descriptors; S2: Create the i-th file descriptor in the queue and send the i-th first access request packet through the i-th file descriptor, and The source port recorded by the i-th file descriptor is monitored; S3: every first preset time interval t 1 , let i increase by 1, continue to execute step S2, and set the preset listening time T for each source port, T=t 1 *m; S4: at m*j

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method for sending data. The present application also relates to a data sending device, a method and system for establishing a P2P connection, a computing device, and a computer-readable storage medium. Background technique [0002] NAT technology is a technology that converts the private IP address of the internal network to the public IP address of the external network. It enables multiple hosts within a certain range to use only one public IP address to connect to the external network. Although NAT technology solves the problem of IPv4 address shortage to a certain extent, it destroys peer-to-peer (P2P) network communication. The main reason is that NAT does not allow external network hosts to actively access internal network hosts. NAT types are divided into 4 types: full cone, restricted cone, port-restricted and symmetric, and there are 10 combinatio...
