Ethernet link Data rate

[fikayo afowowe]

Hello Team,

is it possible to create a custom Ethernet link data rate.

I plan on using a link less than or equal to 1Mbps between my devices, OpenFlow switches and controller.

I know its possible to vary PPP link data rate but PPP wont work for me since the Openflow framework works only with ethernet headers (only connections with ethernet link works) 

Thanks.

It is possible but you will need to modify the source code, for example, you will need to include the characteristics of the your ethernet in the descriptor

const EthernetMacBase::EtherDescr EthernetMacBase::etherDescrs[NUM_OF_ETHERDESCRS] = {

Thanks for the response Alfonso.

I was able to achieve this by editing the inet/linklayer/ethernet/common/Ethernet.h file.

I edited the speed on this line to what I wanted #define TWOANDHALFGIGABIT_ETHERNET_TXRATE

This would also serve the purpose perfectly right?

I think that it should be enough but test it, it is the fastest to check if it works.

Yes, I guess it works. I have varied over different data rates. The results improve as I increase the data rate.

Also, bigger frames improve the throughput
