Enhancing the
Performance of Your
Network
Figure 26
shows how you can set your network up to enhance its
performance.
All ports are auto-negotiating and smart auto-sensing and will therefore
pass data across the network at the optimum available speed and duplex
mode. Flow control will help avoid packet loss during periods of network
congestion. A Gigabit Ethernet backbone is set up between the Switch
4900 and each Switch in the workgroups to increase the bandwidth, and
therefore the overall network performance.
