The Need For Protocol Architecture

Network Architecture or Protocol Hierarchies

• Interface
• Adjacent-layer interaction on the same computer
• Same-layer interaction on different computers

OSI reference Model

• Application Layer
• Presentation Layer
• Session Layer
• Transport Layer
• Connection-oriented
• Connectionless
• Segmentation and sequencing
• Connection establishment
• Flow control (or windowing)
• Network Layer
• Data-Link Layer
• Logical Link Control (LLC) sub layer
• Media Access Control (MAC) sub layer
• Physical Layer

OSI Layering Concepts and Benefits

• Standard Interfaces
• Easier to learn
• Easier to develop
• Multivendor interoperability
• Modular engineering

TCP/IP reference model

• TCP/IP Application layer
• TCP/IP transport layer
• The TCP IP internet Layer
• The TCP IP Network access layer

Multiplexing: FDM TDM 

• Frequency division multiplexing
• TDM v/s FDM

Connection Oriented and Connectionless Services

• connection oriented service
• connectionless service
