Abstract

The invention provides a data sending method, a data sending device, a P2P connection establishing method and a P2P connection establishing system. The data sending method comprises the following steps: S1, establishing a queue for accommodating m file descriptors for n1 first access request data packets; S2, creating an ith file descriptor in the queue, sending an ith first access request data packet through the ith file descriptor, and monitoring a source port recorded by the ith file descriptor; S3, every first preset time interval t1, making i automatically increase by 1, the step S2 continues to be executed, preset monitoring time T is set for each source port, and T = t1 * m; S4, under the condition that i is smaller than or equal to m * (j + 1) and greater than m*j, when the ith file descriptor is created in the queue, monitoring on the imth source port is ended, the corresponding file descriptor is destroyed until it is monitored that the first port receives the response data packet, monitoring on other source ports is stopped, and the first port is any source port in a monitored state.

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...
