#9: Insufficient bandwidth
Sometimes, a network just doesn't have the throughput it requires. As with # 6--excessive network-based applications--some environments demand more bandwidth than others.
When a network does bog down, several options typically exist for increasing capacity. Besides boosting up- and downstream speeds, some offices may require additional dedicated connections. From multiple T1s to DS3s to even optical carrier-grade connectivity, many potential solutions exist.
Further, some organizations may need to upgrade existing 10/100 Mbps networks to gigabit speeds. By upgrading NICs, cabling, and devices to 10/100/1000 Mbps equipment--and replacing any remaining hubs with switches--many firms can realize significant capacity gains. In other cases, it may be necessary to subnet networks to localize particularly intense traffic to specific network segments.
