A Services Descriptions

Our discussion above has identified many of the pieces that structure the Internet. But we can also explain the Internet from completely different angle - namely, as an infrastructure that gives services to applications. These applications contain electronic mail, Web surfing,

Network Protocols
Network Protocols

A network protocol is like a human protocol, except that the entities exchanging messages and taking actions are hardware or software elements of some device (for instance, computer, PDA, cell phone, router, or other network-capable device). All activity in the Internet that

How Do Packets Make Their Way Through Packet-Switched Networks
How Do Packets Make Their Way Through Packet-Switched Networks

Earlier we said that a router takes a packet arriving on one of its connected communication links and forwards that packet on to another of its connected communication links. But how does the router decide the link onto which it should forward the packet? This is actually done in

Transmission Delay - Propagation Delay
Transmission Delay - Propagation Delay

Assuming that packets are transmitted in a first-come-first-served manner, as is common in packet-switched networks, our packet can be transmitted only after all the packets that have arrived before it have been transmitted. Indicate the length of the packet by L bits, and

Principles of Network Applications
Principles of Network Applications

Consider you have an idea for a new network application. Maybe this application will be a great service to humanity, or will please your professor, or will bring you great wealth, or will simply be fun to develop. Whatever the motivation may be, let's now study how you

Non-Persistent and Persistent Connections
Non-Persistent and Persistent Connections

In various Internet applications, the client and server communicate for an extensive period of time, with the client making a series of requests and the server responding to reach of the requests. Depending on the application and on how the application is being used, the series of

DNS -The Internets Directory Service

We human beings can be recognized in many ways. For instance, we can be recognized by the names that appear on our birth certificates. We can be recognized by our social security numbers. We can be recognized by our driver's license numbers. Though each of these identifiers

Circular DHT
Circular DHT

To deal with this problem of scale. let's now look at organizing the peers into a circle. In this circular arrangement, each peer only keeps track of its immediate successor (modulo 2n). An instance of such a circle is shown in Figure 1(a). In this instance, n is again 4 and there are

Pipelined Reliable Data Transfer Protocols
Pipelined Reliable Data Transfer Protocols

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.

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
