Comms – Mainframe Network Architecture 3.1
Duration
5 hours
Overview
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 discusses 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, the student will 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
