1 Arsitektur Jaringan Pertemuan 09 Matakuliah: H0484/Jaringan Komputer Tahun: 2007

2 Bina Nusantara Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu : – Menjelaskan konsep jaringan model OSI – Menjelaskan model TCP/IP

3 Bina Nusantara Outline Materi Layering model Model OSI 7 layer Model TCP/IP Relasi

4 Bina Nusantara OSI - The Model Open Systems Interconnection developed by the International Organization for Standardization (ISO). A theoretical system using a layering model Each layer performs a subset of the required communication functions Each layer relies on the next lower layer to perform more primitive functions Each layer provides services to the next higher layer Changes in one layer should not require changes in other layers

5 Bina Nusantara OSI Model

6 Bina Nusantara OSI Layers

7 Bina Nusantara Physical Physical interface between devices  Mechanical  Electrical  Functional  Procedural OSI Layer -1

8 Bina Nusantara Data Link Means of activating, maintaining and deactivating a reliable link Error detection and control Higher layers may assume error free transmission OSI Layer - 2

9 Bina Nusantara OSI Layer - 3 Network Transport of information Higher layers do not need to know about underlying technology Not needed on direct links

10 Bina Nusantara OSI Layer - 4 Transport Exchange of data between end systems Error free In sequence No losses No duplicates Quality of service

11 Bina Nusantara Session Control of dialogues between applications Dialogue discipline Grouping Recovery OSI Layer - 5

12 Bina Nusantara Presentation Data formats and coding Data compression Encryption OSI Layer - 6

13 Bina Nusantara Application – Means for applications to access OSI environment OSI Layer - 7

14 Bina Nusantara Summary of Layer Functions

15 Bina Nusantara TCP/IP Protocol Architecture Developed by the US Defense Advanced Research Project Agency (DARPA) for its packet switched network (ARPANET) Used by the global Internet No official model but a working one. – Application layer – Transport layer – Internetworking layer – Network access layer – Physical layer

16 Bina Nusantara PDUs in TCP/IP

17 Bina Nusantara Internet Layer (IP) Systems may be attached to different networks Routing functions across multiple networks Implemented in end systems and routers

18 Bina Nusantara Application Layer Support for user applications – HTTP, SMPT

19 Bina Nusantara OSI v TCP/IP

20 Bina Nusantara TCP/IP Concepts

21 Bina Nusantara Addresses in TCP/IP
