TCP/IP Protocol Suite

• Host-to-network : Physical and data link layer– No specific protocol

• Network layer– IP(Internet Protocl), ARP(Address Resolution Protocol),

RARP(Reverse ARP), ICMP(Internet Control Message Protocol), IGMO(Internet Group Message Protocol)

• Transport layer– TCP(Transmission Control Protocol), UDP(User Datagram Protocl),

SCTP(Stream Control Transmission Protocol),

• Application Layer– Combined session, presentation, and application layers

Frequency Division Multiplexing• FDM is an analog multiplexing technique that combines analog signals• Signals modulate different carrier frequencies• Modulated signals are combined into a composite signal• Channel - Bandwidth range to accommodate a modulated signal• Channels can be separated by strips of unused bandwidth (guard

band) to prevent overlapping

IEEE Standards• In 1985, the Computer Society of the IEEE started a project, called In 1985, the Computer Society of the IEEE started a project, called

Project 802, to set standards to enable intercommunication among Project 802, to set standards to enable intercommunication among equipment from a variety of manufacturers. Project 802 is a way of equipment from a variety of manufacturers. Project 802 is a way of specifying functions of the physical layer and the data link layer of specifying functions of the physical layer and the data link layer of major LAN protocols.major LAN protocols.

Network Topology

The network topology defines the way in which computers, printers, and other devices are connected. A network topology describes the layout of the wire and devices as well as the paths used by data transmissions.

Introduction to Computer Networks

Page 19: Kuliah Komunikasi Data. Lima Komponen Komunikasi Data Message: Information(data) to be communicated Sender Receiver Transmission medium: Physical path.

The IP Addressing Scheme• Addressing is specified by the Internet Protocol ( IP )• Internet protocol address or IP address– A unique 32-bit binary number– Used for all communication with the host

• Each 32-bit IP address is divided onto two parts– A prefix and a suffix

• Network number– A unique value assigned to each physical network

• The IP address hierarchy guarantees that– Each computer is assigned a unique address– Suffixes can be assigned locally without global coordination

Page 20: Kuliah Komunikasi Data. Lima Komponen Komunikasi Data Message: Information(data) to be communicated Sender Receiver Transmission medium: Physical path.

Classes of IP Addresses• The class of an address determines the boundary between the

network prefix and host prefix• IP divides host address into their primary classes A, B and C• The first four bits of an address determines the class• To use IP multicasting, a set of hosts must agree to share a

multicast address

Page 21: Kuliah Komunikasi Data. Lima Komponen Komunikasi Data Message: Information(data) to be communicated Sender Receiver Transmission medium: Physical path.

Every machine on the Internet has a unique

identifying number, called an IP Address.

A typical IP address looks like this:

216.27.61.137

But computers communicate in binary form.
