What is FECN {Forward Explicit Congestion Notification)
hi kapilashdhir
thanks for the question here is the i am trying to provide answer

fecn=this is a mechanism of frame really congestion control

as we know that in the frame realy mechanism we have some link of limted bandwidth
but if another link is available then we can use that link for our data forwarding.

suppose we are forwarding some data through farme realy network moere then our COMMTED RATE.NOW suddnly some link not avlable but we are not aware of that is there is congesstin in network we are continusly forwarding the data at the same rate.
what happen due to this a trafic congusstion will ocur
so for solving that problem two mechnaism come in acount
1 bemcn-bacward explict
2 fecn-forward explict

i hope it will help to understand the farme really technolgy

now how the both are working
i will explain it latter
