This guide provides essential strategies for managing network traffic by optimizing bandwidth utilization. It emphasizes that utilization indicates the percentage of network bandwidth being used and that Ethernet networks perform poorly when utilization exceeds 40%. Key methods include increasing bandwidth and creating smaller collision and broadcast domains through segmentation and VLANs. The importance of tiered bandwidth allocation is discussed, emphasizing the need to place bandwidth where it's most required, such as on high traffic servers and backbone links.

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:
