Question 1: Reliable Data Transfer Protocols (20 points) 1.1: What are the assumptions on the channel for rdt 1.0, rdt 2.0, rdt 2.1 and rdt 3.0? What are the mechanisms applied in each of these protocols to achieve reliable data transfer? (10 points) 1.2: Draw the finite-state machine (FSM) for the receiver side of protocol 3.0.
