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:
