Layers of the TCP / IP Protocol As with software, TCP / IP is built into

Like software, TCP / IP is formed in multiple layers. Made in layered, will facilitate the development and implementation. The inter layer can communicate up and down with the interface interface. Each layer has different functions and uses and supports each layer on it. In the TCP / IP protocol is divided into 4 layers, shown in Figure

Protokol TCP/IP

Application Layer (Applications)

Application layer used in the program to communicate using TCP / IP. Examples of applications include Telnet and File Transfer Protocol (FTP). Interfaces that are used to communicate with each other are port numbers and sockets.

The Transport Layer

Transport Layer provides an end-to-end data delivery function to the remote side. Various applications can communicate simultaneously (simultaneously). The most commonly used transport layer protocol is the Transmission Control Protocol (TCP), which provides data-sharing capabilities, data duplication prevention, congestion control and flow control. Another protocol is the User Datagram Protocol (UDP), which provides a connectionless delivery function, an unreliable path. UDP is widely used in applications that require high speed and can be metoleransi against data damage.

Layer Internetwork

Layer Internetwork commonly called the internet layer or network layer, which provides a "virtual network" on the internet. Internet Protocol (IP) is the most important protocol. IP sends routing functions on the network in data transmission. Other protocols include: IP, ICMP, IGMP, ARP, RARP

Layer Network Interface

The network interface layer is also called the link layer or datalink layer, which is the hardware on the network. Examples: IEEE802.2, X.25, ATM, FDDI, and SNA.

In detail can be added in Figure Bel below:

TCP / IP Application

The level in the TCP / IP layer is the application. Where this layer communicates so that it can interact with the user.

Characteristics of application protocols include:

 An application program created by the user or application that is a standard of TCP / IP products. Examples of applications that are products of TCP / IP include

o TELNET, an interactive terminal for accessing a remote on the internet.

o FTP (File Transfer Protocol), high-speed file transfer between disks.

o SMTP (Simple Mail Transfer Protocol), the system is written in the network

o etc.

➮ Use the TCP or UDP mechanism.

➮Using client/server interaction model.
