Lecture Objectives
• Layered Network Architectures
• The Communication Process
• Protocol and Reference Models
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
TCP/IP Layered Architecture Model
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
Benefits of Layering
1. Assists in protocol design
2. Open standard - fosters competition
3. Changes made in one layer do not affect other layers
4. Defines common terms that describe the network functions
5. Provides a common (standard) language
6. Allows technologies and protocols to evolve
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
The Communication Process
HET104/HET706 Slide Set 1 – Network Architecture Models

Protocol Data Units (PDU) and Encapsulation
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
The process of sending and receiving messages
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
Protocol and Reference Model
A Protocol Model
• provides a model that closely matches the structure of a particular protocol suite – TCP/IP
A Reference Model
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
A Reference Model
• provides a common reference for maintaining consistency within all types of network protocols and services -OSI
ISO/OSI and TCP/IP Models
OSI – Open Systems Interconnection, ISO – International Organisation for Standardisation
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
Each Layer of the OSI Model
• Physical• Accepts frames, transmits as binary data, bits, over media between
devices
• Data Link
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
• Data Link• Accepts packets, creates frames, places packets in frames for host to
host delivery across a single link, on the LANs and WANs
• Address Label – source and destination MAC (Media Access Control) address
Each Layer of the OSI Model
• Network
• Accepts segments from layer above, create packets, places segments in packets for end-to-end delivery through intermediary devices in other networks to the destination
• Address Label – source and destination IP address
• The IP address identifies the HOST device
• Transport
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
• Transport
• At the source, accepts data from layer above, creates segments, places data in segments and numbers them,
• transfers the segments,
• At the destination, reassembles the data from the segments and passes data to layer above
• Address Label – source and destination Port number
• The Port number identifies the application
Each Layer of the OSI Model
• Session• Manages sessions between users
• Synchronizes web sessions, voice and video data in web conferences
• Presentation• Provides data format information to the application (layer)
• Data encrypted, data is .jpg picture, data compressed
HET104/HET706 Slide Set 1 – Network Architecture Models
jbut@swin.edu.au, pgranville@swin.edu.au
• Data encrypted, data is .jpg picture, data compressed
• Application• Perform services for the applications used by the end users
• DNS, HTTP, FTP, SMTP
• TCP/IP Application Layer maps onto all the above OSI
layers
In Summary the Lecture has covered:
• Layered Network Architectures
• The Communication Process
• Protocol and Reference Models
