Overview: The Internet Protocol (IP) suite of networking designs is used worldwide to interconnect heterogeneous systems using modern networks. Transaction Processing Facility (TPF) supports these designs to enable users to connect directly to the many networking systems using these protocols. This class presents the abilities and limitations of TPF in this environment including descriptions of TPF's support for Transmission Control Protocol (TCP), User Datagram Protocol (UDP) and the Raw IP.

Audience: Programmers with a need to define and control a TCP/IP network and/or TCP/IP networking professionals who have little working knowledge of TPF, but who need to know TPF's capabilities.

Educational Objectives: Learn to incorporate TPF into a TCP/IP networking environment and to successfully control that environment.

Topics: The following topics will be addressed in the class:

Networking Definitions
Socket and SSL Review
Hardware Support in TPF
Overview of Offload and CLAW
Channel Data Link Control (CDLC) and Local IP Routers
QDIO/STI and the Open System Adapter-Express (OSA-E)
The IP Datagram
Network Design in a TPF Environment
Traces
Network Control in a TPF Environment
The Internet Daemon
Overview of the Higher Level Protocols, including:
Trivial File Transfer Protocol (TFTP)
File Transfer Protocol (FTP)
Mapping Airline Traffic over IP (MATIP)
MQ Local Manager (MQ)

Prerequisites: An understanding of operating system and network design is needed (operating systems other than TPF and networks other than TCP/IP are acceptable). A basic understanding of the socket API is required (this may come from experience or from the TCP/IP for TPF: Introduction and the API course). S/390 Assembler knowledge is needed as a basis for learning about the support for internal stacks and being able to look at tables in their hexadecimal representations in sample dumps.

Format: Traditional Stand Up Lecture with hands on exercise
