Abstract

The invention discloses a network penetration method, apparatus and system, and a network connectivity checking method. The method comprises the following steps: in the case of data transmission between two terminals in different local networks, allocating a plurality of local ports to each session established for the data transmission between two terminals; obtaining a public network port mappedby each local port to a public network so as to obtain a plurality of public network ports; and performing connectivity check on the plurality of public network ports one by one, and transmitting databy using the public network ports passing the connectivity check. By adoption of the invention, the technical problem of low network penetration efficiency during the data transmission of two terminals in the local network through local addresses by using a network address converter in the prior art is solved.

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...
