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.
