Why both Data link layer and Transport layer do Error Checking?
I have a very simple question. Basically information converted in to stream of bits (1's and 0's) and transmit, in the receiving end Both Link layer and Transmission Layer runs error checking. Any one please elaborate why is these two checks?
It might, but that would negate both the independence of each layer being independent for error checking.
BTW, why the concern of the multiple checks? If you're worried about efficiency, years ago I encoded a CRC-32 check in assembler that was based on a table lookup - i.e. it didn't have to do the polynomial match.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
