Building a Reliable Data Transfer Protocol
Building a Reliable Data Transfer Protocol

We first examine the simplest case, in which the underlying channel is completely reliable. The protocol itself, which we'll call rdt1.0, is trivial. The finite-state machine (FSM) definitions for the rdt1.0 sender and receiver are shown in Figure 1. The FSM in Figure 1(a) defines the

Protocol rdt3.0 is a functionally correct protocol, but it is doubtful that anyone would be happy with its performance, especially in todays high-speed networks. At the heart of rdt.3.0s performance problem is the fact that it is a stop-and-wait protocol.
