           │ > Consider a system essentially consisting of a sender S and a receiver R that communicate with each other over channels c and d. The receiver sends messages to the sender via channel d, and the │
           │ sender sends messages to the receiver via channel c. It is assumed that both channels have an unlimited buffer. Channel c is unreliable in the sense that data may get lost when being transmitted │
           │ from the sender S to channel c. Once messages are stored in the buffer of channel c, they are neither corrupted nor lost. Channel d is assumed to be perfect. The goal is to design a              │
           │ communication protocol that ensures any distinct transmitted datum by S to be delivered to R. To ensure this in the presence of possible message losses, sender S resorts to retransmissions.      │
           │ Messages are transmitted one by one, i.e., S starts sending a new message once the transmission of the previous message has been successful. This is a simple flow control principle, known as     │
           │ "send-and-wait". Each message m from S is sent with a control bit b, and when R receives this, it sends an acknowledgement consisting of the control bit it just received. On receipt of the       │
           │ acknowledgement, S sends a new message with the negation of the control bit. If S has to wait too long for the acknowledgement, it times out and retransmits the original message and control bit. │
           │ Build a model of this system, using submodules for S and R. Use the variable names c, d, S, R, m and b.                                                                                            │

           │ > Consider a system essentially consisting of a sender S and a receiver R that communicate with each other over channels c and d. The receiver sends messages to the sender via channel d, and the │
           │ sender sends messages to the receiver via channel c. It is assumed that both channels have an unlimited buffer. Channel c is unreliable in the sense that data may get lost when being transmitted │
           │ from the sender S to channel c. Once messages are stored in the buffer of channel c, they are neither corrupted nor lost. Channel d is assumed to be perfect. The goal is to design a              │
           │ communication protocol that ensures any distinct transmitted datum by S to be delivered to R. To ensure this in the presence of possible message losses, sender S resorts to retransmissions.      │
           │ Messages are transmitted one by one, i.e., S starts sending a new message once the transmission of the previous message has been successful. This is a simple flow control principle, known as     │
           │ "send-and-wait". Each message m from S is sent with a control bit b, and when R receives this, it sends an acknowledgement consisting of the control bit it just received. On receipt of the       │
           │ acknowledgement, S sends a new message with the negation of the control bit. If S has to wait too long for the acknowledgement, it times out and retransmits the original message and control bit. │
           │ Build a model of this system, using submodules for S and R. Use the variable names c, d, S, R, m and b.                                                                                            │
