Simplex & Stop and Wait Protocols- Flow Control Protocols for Noiseless Channel- A Role Play
Flow control refers to a set of procedures used to restrict the amount of data that the sender can send before waiting for acknowledgment.
Ensuring the sending entity does not overwhelm the receiving entity
Preventing buffer overflow
Protocols for Noiseless Channel:
1. UTOPIA Simplex protocol
2. Stop-and-Wait Protocol
Simplex protocol
• Sender has continuous data
• Data transmitted in one direction only
• Transmitting and receiving layers are always ready
• Infinite buffer space at receiver
• Processing time is ignored
• Ideal communication channel - no loss, no errors
Simplex Stop-and-Wait Protocol
• Consider a slow receiver
• no buffer space at receiver
• Sender sends one frame and stops, waits for acknowledgement
• channel is still error free and traffic is simplex
