TCP/IP on z/TPF

This course takes you on a journey with a remote client, Joe, as he interacts with the z/TPF system over the network. Joe wants to check his account balance from a banking application running on the z/TPF system. He begins by establishing a TCP connection with the z/TPF banking application. Joe then sends a request to obtain his account balance, which is received by the z/TPF banking application. After processing the request, the z/TPF banking application sends a response back to Joe to complete the request. Each unit builds on the previous one to paint a complete picture of the TCP/IP processing involved in Joe’s account balance request.

Syllabus

Understand the key TCP/IP control structures and processes within z/TPF.
Understand how a TCP application server is created through the z/TPF internet daemon (InetD) and how a remote client establishes a TCP connection to this server.
Understand the flow of an inbound message received by the z/TPF system—from its arrival over the network to its delivery to the application.
Understand the flow of an outbound message sent by a z/TPF application—from the time the application sends the output message to when the remote client acknowledges the receipt of the message.
