A SEMINAR ON

IMPLEMENTATION OF
ISO
-
OSI
ARCHITECTURE

1

Idea

2



Idea for the network design based upon ISO
-
OSI
architecture has come from the implementation
strategies followed by big brand of “CISCO
INDUSTRIES PVT. LTD.” while designing data
communication networks



Standardization of Network



Data communication networking norms and privileges

Objectives

3


To study and understand ISO
-
OSI reference model and
architecture hierarchy


Relationships Between


Layers Entities in the respective layers


Protocols in the respective Layers


Interfaces


Services


Protocol Data Units


Implementation of this network architecture in the network
design for data communication in the project of “MODEL
CONTACTORS FOR DRYING PROCESS”


Categorization of interfaces into respective Layers

Flow of presentation

4


General network design issues



ISO
-
OSI Reference Model


Protocol Data Unit


Project Summary


Mapping the implemented network into ISO
-
OSI Model


Layouts of how network is built according to this
standard


Overall network summary


Conclusions

General network design issues

1] Network Hardware


Transmission Technology

a.
Broadcast Links

b.
Point to Point Links



Scale


6

2] Network Software


Protocol Hierarchy


Design issues for the


layers



7

3] Services to the above layer


Protocol Data Unit


8



The Layer 1 (Physical Layer) PDU is the a data bit


The Layer 2 (Data Link Layer) PDU is the a data
frame


The Layer 3 (Network Layer) PDU is the data packet


The Layer 4 (Transport Layer) PDU is the segment

Study of ISO
-
OSI hierarchy in depth



Implementation of standard into actual network for
data communication



Widely used model as its architecture is quite
popular
