Embodiment Construction

[0064] In order to solve the problem in the prior art that the client must pass the STUN server to complete the detection of the type of network it is in, the technical solution of the present invention proposes a method where the client where the user is located selects two public network nodes in the public network , to replace the STUN server with the two selected public network nodes to complete the processing method of the STUN test.

[0065] The main realization principles, specific implementation methods and corresponding beneficial effects of the technical solution of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0066] Please refer to Fig. 2, this figure is the main realization principle flowchart of the method for detecting network type of the present invention, and its main realization process is as follows:

[0067] Step S01, the user logs in to the public network, and selects two public network nodes with ...

Abstract

The invention discloses network type detecting method and system. It includes the following steps: loading public network; selecting public network nodes which has two IP addresses; sending request packet to the first or second nodes by STUN protocol; replying the response packet; confirming the network type. The invention can make the user detect the network type without STUN server which can greatly reduce hardware cost, avoid single point of failure.

Description

technical field [0001] The invention relates to computer network technology, in particular to a method and system for detecting network types. Background technique [0002] NAT (Network Address Translators, Network Address Translation) is a technology that maps an IP address from one addressing domain to another. Its most typical application is to map the private IP address defined by RFC1918 to the Internet. Public IP address. NAT can enable multiple hosts to share the Internet connection. This function solves the problem of shortage of public network IP addresses. [0003] Traditional NAT mapping methods mainly include the following typical types: [0004] (1) Fully transparent NAT (Full Cone NAT) [0005] Fully transparent NAT maps all requests from internal hosts with the same internal IP address and port number to the same external IP address and port number, and any external host sends data packets to the external IP address and port number mapped by the internal ho...
