Dengan menggunakan subnet mask yang diasosiasikan dengannya, sebuah alamat IP pun dapat dibagi menjadi dua bagian, yakni Network Identifier NetID yang dapat mengidentifikasikan jaringan lokal dalam sebuah internetwork dan Host identifier HostID yang dapat mengidentifikasikan host dalam jaringan tersebut.

In this tutorial we will look at networking protocol models, and explain how and why they are structured into layers. Networking equipment and networking levels What is a Protocol? A protocol is a set of rules that govern how systems communicate.

IP, Internet Protocol

For networking they govern how data is transferred from one system to another. What is a Protocol Suite? A protocol suite is a collection of protocols that are designed to work together. Protocol Stacks It is possible to write a single protocol that takes data from one computer application and sends it to an application on another computer.

The approach used in networking is to create layered protocol stacks. Each level of the stack performs a particular function and communicates with the levels above and below it.

This layered arrangement is not confined to networking, and how it works is probably best understood if you compare it to real life example.

Protocol Layers and the OSI Model

Lets take an example of a parcel service between two offices. The task is simple — send parcels between people in each office. We will divide the task into two distinct processes as follows: Take a package, wrap it and address it. Send it to the destination at the receiving end Deliver it to the recipient Typically you would have an internal mail man that: Collects the parcels from the senders and takes then to a mail dispatch room.

The parcels are placed in a van by the dispatcher and then driven to the remote office. At the remote office The parcels are received by the dispatcher and placed into a tray for the mail man The mail man collects the parcels and delivers them to the recipients, Here is a simple diagram to illustrate the process: So if for example, if we decide to use a train instead of a van to transport the messages between the offices we could do so without affecting the mail man.

Although this appears very simple, and maybe trivial, it does illustrate some very important points that are crucial when it comes to understanding networking protocols and how they are organised.

It is important to understand that this model provides for a conceptual framework, and no modern protocols implement this model fully. For example you should theoretically be able to replace the IP networking protocol with the IPX networking protocol without affecting how the application e.

End to End Connections- Routers,Switches and OSI When two computers communicate across a network the data must travel through various items of networking equipment.

You will often hear the terms level 2 and level 3 equipment used. A router for example works at the networking layer and is a level 3 device.

A switch operates at the Ethernet level and is a level 2 device. To do protocol conversion you will need a Gateway. Because the switch operates at level 2 data link layer it only needs to understand the MAC addresses that are part of the Ethernet protocol.

The earliest use, and the most common use is over Ethernet networks.

Internet protocol suite

Applications will choose which transmission protocol to use based on their function. IP Internet Protocol — This is the main networking protocol.Una suite di protocolli Internet, in informatica e in telecomunicazioni, indica un insieme di protocolli di rete su cui si basa il funzionamento logico della rete Internet.A volte, per sineddoche, è chiamata suite di protocolli TCP/IP, in funzione dei due più importanti protocolli in essa definiti: il Transmission Control Protocol (TCP) e l'Internet Protocol .

Introducing the Internet Protocol Suite. This section presents an in-depth introduction to the protocols that compose TCP/IP. Although the information is conceptual, you should learn the names of the protocols and what each does.
