Principles of Reliable Data Transfer
Principles of Reliable Data Transfer

In this section, we look at the problem of reliable data transfer in a general context. This is appropriate since the problem of implementing reliable data transfer takes place not only at the transport layer, but also at the link layer and the application layer as well. The common

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

Connection-Oriented Transport - TCP
Connection-Oriented Transport - TCP

We have studied the underlying principles of reliable data transfer, let's examine TCP - the Internet's transport-layer, connection-oriented, reliable transport protocol. In this section, we'll see that in order to provide reliable data transfer, TCP relies on many of the underlying
