Do Nothing (Toss the Frame/Packet)

Do Nothing is a method where the receiver discards the erroneous frame or packet without notifying the transmitter.

  • Application: Used in some lower-layer protocols like Frame Relay.
  • Mechanism: If an error is detected, the frame is simply discarded.
  • Assumption: Higher-layer protocols (e.g., TCP/IP) are expected to handle retransmission by detecting the missing or erroneous frame.
