Abstract

The invention discloses a network penetration method, device, system and network connectivity checking method. Wherein, the method includes: in the case of transmitting data between two terminals located in different local networks, allocating multiple local ports for each session established for transmitting data between the two terminals; obtaining the mapping of each local port in the public The public network ports of the network are obtained to obtain multiple public network ports; the connectivity checks are performed on multiple public network ports one by one, and the public network ports that pass the connectivity check are used to transmit data. The invention solves the technical problem of low network penetration rate in the prior art when a network address translation server is used to enable two terminals located in a local network to transmit data through local addresses.

Description

technical field [0001] The present invention relates to the field of the Internet, in particular to a network penetration method, device, system and network connectivity checking method. Background technique [0002] IPv4 is the fourth version of the Internet Protocol (IP), and the first widely used protocol that forms the basis of today's Internet technology. The number of digits in an IPv4 address is 32 bits, that is to say, computers with a maximum of 2 to the power of 32 can be connected to the Internet. Due to the vigorous development of the Internet, the demand for IP addresses is increasing, making IP addresses exhausted. . However, the number of addresses in IPv6 is 128 bits, which can provide almost unlimited IP addresses. However, because the existing huge amount of network configurations only support IPv4, before fully switching from IPv4 to IPv6, in order to solve the problem of shortage of IPv4 addresses, NAT (Network Address Translation, Network Address Trans...
