Managing Network Traffic by Design


Utilization
Utilization

  • Utilization means the % of network bandwidth being used.

  • Ethernet performs badly when utilization exceeds 40%.


Traffic management
Traffic Management

  • When LAN utilization is high

    • Increase bandwidth.

    • Create smaller collision domains - segment with switches

    • Create smaller broadcast domains - partition LANs into smaller VLANs; cross-connect with routers.


Bandwidth
Bandwidth

  • When designing bandwidth allocations

    • Put bandwidth where it is needed:

      • High traffic servers

      • High traffic backbone links

    • Use tiered bandwidth - a hierarchical approach.


Tiered bandwidth
Tiered Bandwidth

  • Bandwidth can be placed where it is needed most:
