Tips & Best Practices

Keep in mind protocol overhead and framing differences when interpreting converted values
Use conversion results as nominal rates rather than guaranteed throughput
Apply conversions mainly for planning rather than precise performance measurement
Combine tool results with network condition assessments for accurate capacity planning

Limitations

The OC768 rate reflects optical carrier line speed and includes SONET framing overhead not present in Ethernet rates
The conversion assumes ideal conditions and does not factor in physical layer differences or hardware constraints
Effective usable bandwidth can be lower due to network conditions and protocol inefficiencies
