There are a myriad of monitoring packages that can help you gauge the utilization of your various segments and to determine if there is congestion. Some of these are:
Note that some of these are not available for Fast Ethernet, e.g., we currently have only 10 Mbps Sniffers.
|Speed||Bit Time||Slot Time|
|10 Mbps||100 ns||51.2 µs|
|100 Mbps||10 ns||5.12 µs|
|1000 Mbps||1 ns||0.512 µs|
Note that both copper and fiber media have Distance-Bandwidth specifications:
|Frequency||MM Fiber||Cat 5|
|250 MHz||2 km||100m|
|500 MHz||1 km||50m|
Class I repeaters typically use the additional time for translating signals from one media to another, e.g., 100BaseTX to 100BaseFX.
