Chapter 3 TDI Transports and Their Clients

This describes, in general, the relationship between Windows NT TDI transport drivers and TDI kernel-mode clients, such as higher level network-interface emulators, redirectors, and servers, that communicate with any transport protocol stack using the system-defined TDI interface. That is, this provides an overview of the following:

• The Transport Driver Interface (TDI) in Section 3.1 

• How TDI uses file objects to represent network entities in Section 3.2, including the following three basic TDI entities:
  1. Transport Addresses in Section 3.2.1 

  2. Connection Endpoints in Section 3.2.2 

  3. Control Channels in Section 3.2.3 

• The set of transport driver Dispatch routines required by TDI in Section 3.3 

• The interactions between TDI clients and their underlying transports in Section 3.4 

• The distinction between TDI requests and events in Section 3.5
