Chabot College ELEC 99.05 Managing Network Traffic by Design

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

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 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 Bandwidth can be placed where it is needed most:
