This page contains some simple JavaScript applets that automate recurrent bandwidth and frame rate conversions for Ethernet networks. Enjoy!
 

Bandwidth to frame rate converter.
How many packets of a certain size correspond to a specific bandwidth on an Ethernet Network?

 Frame Size, Including FCS*:  

 Bandwidth (Mbps):                     


 

 Frame Rate is Frames per Second

Full bandwidth to frame rate converter.
What is the maximum amount of packets with a certain size that can be transmitted on an Ethernet network?

 Frame Size, Including FCS*:    

 Network Speed:                         


 

 Max Frame Rate is Frames per Second

 

Frame rate to bandwidth converter.
What is the total bandwidth generated by a certain frame rate, including Inter frame Gap and Preamble?
 Frame Size, Including FCS*:  

 Frame Rate:                                


 

Bandwidth is Mbit per Second

Uilization calculator.
What is the effective bandwidth carried by an Ethernet Network with frames of a certain size? **

   Frame Size, Including FCS*:  

   Network Speed:                         


 

Utilization is %, or Mbit per Second


Notes:

* Frame size including FCS can be between 64 and 1518 bytes for regular Ethernet frames, and between 64 and 1522 bytes for VLAN tagged frames.
** Effective Bandwidth is calculated as: Total Bw - (Preamble Bw + Inter Frame Gap Bw + FCS Bw + Ethernet Headers Bw).
