Reliable Transmission

Reliable Transmission. How to fix corrupted frames. Error correcting codes too expensive Should discard frames (retransmission) Recover from Corrupt Frames should be done in the Link Level. Reliable Transmission. Recovery is accomplished with two mechanisms Acknowledgements (ACK)
