Protocol performance:

  • The throughput efficiency is the measure of the performance of an ARQ protocol. For any channel a certain bandwidth and bit error rate are specified.
  • For such a channel there will be an optimum operating condition that will support for the maximum "Net Data Throughput" (NDT).
  • NDT indicates …
