Network transport layer Filtering (TDI, transport layer interface filtering)

TDI (transport layer interface) is a system that supports at least Windows 7. Since Vista, Microsoft has used a new technology to replace TDI, known as windows Filtering Platform ). However, the usage of WINXP in tianchao does not need to be said much. Therefore, we can directly create the interface of the retro transport layer like TDI!

In general, although on the transport layer, the device binding is the same as before. TCP/IP and other protocols also have drivers, which will also generate devices, so we can generate filter devices to bind these devices. The result is that the requests sent from the application layer are first intercepted by the filter device we are bound!

"\ Device \ Tcp", corresponding to TCP protocol

"\ Device \ UPD", corresponding to UDP protocol

"\ Device \ rawip", corresponding to the original IP package
