  1. Chabot College ELEC 99.05 Managing Network Traffic by Design

  2. Utilization • Utilization means the % of network bandwidth being used. • Ethernet performs badly when utilization exceeds 40%.

  3. 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.

  4. Bandwidth • When designing bandwidth allocations • Put bandwidth where it is needed: • High traffic servers • High traffic backbone links • Use tiered bandwidth - a hierarchical approach.

  5. Tiered Bandwidth • Bandwidth can be placed where it is needed most:
