ASSUMPTIONS
The physical layer, data page link layer, and network layer are independent processes.
The network layer contacts the data page link layer by generating proper events.
The data page link layer provides a reliable, connection-oriented service to the network layer.
The physical layer computes/checks checksums in outgoing/incoming frames, and contacts the data page link layer by generating proper events.
UNRESTRICTED SIMPLEX PROTOCOL
It is the simplest though unrealistic protocol with the nick name “UTOPIA“.
data is transmitted in one direction only.
Communication channel between the data page link layers never damages or loses frames.
The protocol consists of two distinct procedures, a sender and a receiver.
No sequence numbers and acknowledgments are used.
