Abstract： |
This invention can find out the concurrent routines number of immediate information software in the detected address by acquiring the data of immediate information software in the network, in order to judge whether NAT is operated in the IP address. It uses the current-unused information of application layer. Users and NAT manufacturers cannot avoid detection by modifying mainframe network protocol stack and NAT gateway. |
