APPN Advanced Peer to Peer Networking

Audience

This seminar is for all technical support and communications staff that wish to be acquainted with APPN.

Prerequisites

Ideally, the student should have a basic understanding of Classic SNA.

Duration

2 days.

Course Objectives

At the end of the course, the delegate should be able to:

• List the main limitations of SNA relative to current-day computing trends, especially Client/Server computing.
• Explain the functions of Low Entry, End and Network Node.
• Compare and contrast APPN domains and addressing versus SNA subareas.
• Itemise major services provided by the APPN Network Node.
• Describe APPN's Topology Database Maintenance function.
• Characterize APPN support.
• Plan a migration from subarea SNA to VTAM APPN.
