This course is offered directly through Core Competence, Inc.  The instructor is David M. Piscitello (dave@corecom.com).

Objectives:

• Understand general concepts associated with Local Area Networking, the nature of shared media, and tranditional LAN segmentation using bridging and routing techniques.
• Understand the merits and advantages of microsegmentation using LAN switching.
• Understand how and when to apply switched internetworking.
• Understand the types and features of LAN switches, and how LAN switches operate.
• Understand how and when to apply virtual LAN technology in switched internetworks.

Audience:

Strategic network planners, network administrators, network operations support staff, analysts, anyone interested in understanding the evolving state of LANs and LAN interconnection.
