The transfer delays and buffer requirements in a cut-through switching network under two error control strategies is the error control done only at the destination node (ECDN). The other is the error control done at every node (ECEN). The numerical examples show that the ECDN strategy can perform better than the ECEN strategy if the increment of traffic intensity due to the error control functions done at every node becomes significant. A simulation is also conducted to verify the validity of the analysis.
