Overview

Description

This course introduces you to core concepts around mainframe networks and communication. Initially the course introduces the different OSI model layers and how they are applied in a mainframe network environment as well as the protocols and technologies used in mainframe network communication. The course introduces SNA and TCP/IP protocols and how they are used in z/OS today. Further to this, the course introduces VTAM and how it works in z/OS as well as discussing how TCP/IP and its features are used in modern mainframe network environments.

Audience

Systems programmers, network technical staff, and z/OS operators who manage z/OS and mainframe networks.

Prerequisites

Successful completion of the Interskill Comms – Network and Communications Concepts 3.1 course or equivalent knowledge.

Objectives

After completing this course, students should be able to:

  • Identify the Seven OSI Layers and what They Do
  • Describe the Different Network Protocols and Technologies Available on IBM Z Mainframe and z/OS.
  • Discuss what Are Subarea Networks, and SNA
  • Identify VTAM and TCP/IP Features on z/OS
  • Describe How TCP/IP Routing Works in a z/OS Environment
