Software that operates at the network layer fragments, routes, and reassembles data. The transport layer works with the network layer to package and transfer data that it receives from the session layer.
The Transmission Control Protocol/Internet Protocol (TCP/IP) operates at the network and transport layers. TCP/IP is an industry standard communication protocol that defines methods for packaging data into packets for transmission over a network. For more information on TCP/IP, see Windows Sockets.
For infrared communications Windows CE supports the Infrared Data Association (IrDA) standards using the IrDA protocols at the network and transport layers. For more information on using the IrDA protocols, see Windows Sockets.
