Overview of NDIS driver types
The Network Driver Interface Specification (NDIS) library abstracts the network hardware from network drivers. NDIS also specifies a standard interface between layered network drivers, thereby abstracting lower-level drivers that manage hardware from upper-level drivers, such as network transports. NDIS also maintains state information and parameters for network drivers, including pointers to functions, handles, and parameter blocks for linkage, and other system values.
NDIS supports the following primary types of network drivers:
These topics detail each type of NDIS driver individually. For more information about the NDIS driver stack and a diagram showing the relationship between all four NDIS driver types, see NDIS Driver Stack.
