NDIS Lightweight Filters

About NDIS Lightweight Filters, Windows Filtering Platform, TDI Filter Drivers

An NDIS Lightweight Filter offers reduced complexity and increased scalability and control over legacy NDIS intermediate (IM) drivers. Rather than requiring both miniport and protocol NDIS interfaces to be implemented, NDIS lightweight filters (LWF) allow developers access to packets as they are processed up and down the Windows networking stack.

Windows Filtering Platform is an alternative filtering platform which allows hooking into the stream and packet processing for the Windows networking stack.

There are no good books on windows networking drivers, or windows filtering platform drivers. However, the Windows® Internals Fifth Edition offers a solid section on the windows networking stack.
