The animated TECHTip Tutorial is available here.

This is an introduction to the planning for QoS [Quality of Service]. QoS is not a single element or single approach. This approach was developed after many months of research but does not include all the issues required. This is more of a framework to begin a dialog. That is, QoS has many hundreds of elements to understanding, evaluating, and deciding.

QoS is really building a plan for QoS at all points. Think of everything in terms of QoS. Number three in the top ten areas is:

Building Zone Management

• Coming from Workspace Zone

• Going to Edge Zone
• Server-Storage Zone - Internal
• Performance Zone(s) - OSI Layers 5-7
• Server type(s)
• Clusters - “server farms”
• Load balancing
• Storage area networks
• Security Access Zone
• LAN through firewall
• LAN - virus scanning
• VO [Virtual Office] - home
• Mobile - “roadies”
• Wiring Zone - Inside Plant - OSI Layer 1
  • SONET - fiber

  • Copper - redundant/diverse
  • Wireless, infrared
• Risers-closets - “last foot”
• Protection Zone - power
  • UPS [Uninterruptible Power Supply] - mission-tolerable

  • UPS + generator - mission-critical
  • Redundant everything else

  • HVAC [Heating-Ventilation Air-Conditioning]
