z/OS Networking

This module explains the basic concepts of TCP/IP and SNA networking and how they have been implemented on the System z™ hardware and the z/OS operating system and its components. The module prepares the student to engage in networking issue resolution with network administrators as an active and informed participate. The module is approximately one half networking theory/architecture and one half business problem resolution. This module is based on the text “Introduction to the New Mainframe: Networking” which is available here. The topics covered in this module include:

• Mainframes and Networks

•  Network layers and protocols

• IP Addressing, Protocol Examples

• Address Exhaustion

• Routing, Encapsulation, Physical Signalling

• Standards, Reliable Messages

• Multiplexing, Virtual LANS
