OSI & TCP/IP Models
- Application Layer: Interface between user and network
- Application protocols facilitate process-to-process communications over IP.
Network Applications
- Examples: E-mail, Internet telephone, Web browsing, Real-time video, Instant messaging, Remote login, P2P file sharing, Multi-user gaming, Streaming video.
Application Architectures
- Types: Client-server, Peer-to-peer (P2P), and Hybrid models.
Network Application Development
- Programs operate across different end systems and communicate via a network.
- Applications communicate using sockets, which serve as endpoints for message exchanges.
Process Communication
- Definitions:
- Client process: Initiates communication.
- Server process: Waits for incoming requests.
- P2P architectures enable inter-host communication through message exchanges.
Sockets
- Sockets function as doorways for message transmission between processes.
- Sending process uses TCP buffers for message delivery.
Process Addressing
- Each process requires a unique identifier, combining an IP address and port number.
- Example Port Numbers:
- HTTP: 80
- Mail: 25
Transport Layer Functions
- Provides logical communication between application processes on different hosts.
- Encompasses various transport protocols, such as TCP and UDP.
Network Layer Functions
- Responsible for segment delivery from sending to receiving hosts.
- Encapsulates segments into datagrams for network transmission.
- Routers examine header fields of IP datagrams for proper routing.
Link Layer Responsibilities
- Transfers datagrams to physically adjacent nodes across wired, wireless, or LAN connections.
- Manages layer-2 packets (frames) for effective datagram transfer between nodes.
