Fundamentals of Networking
Objectives
- Understand networking fundamentals.
- Practical experience with popular network protocols.
- Design and manage networks for application development.
Module 1: Introduction to Networking
Session 1: Networking Basics
- Definition of networking
- Importance of networking in application development
- Common terms and definitions (e.g., IP address, subnet, DNS)
Exercise Part 1:
- Create a basic network diagram for a simple web application.
Session 2: Network Models & Architectures
- OSI and TCP/IP models
- Client-server architecture
- Peer-to-peer architecture
Exercise Part 2:
- Map out the OSI model layers and their functions.
Module 2: Network Protocols
Session 3: Common Network Protocols
- HTTP/HTTPS
- FTP/SFTP
- SMTP/IMAP/POP3
Exercise Part 3:
- Set up a simple HTTP server and test basic GET and POST requests.
Session 4: Advanced Network Protocols
- TCP/UDP
- IPsec
- TLS/SSL
Exercise Part 4:
- Implement a basic TCP client-server application.
Module 3: Network Configuration & Management
Session 5: Network Configuration
- IP addressing and subnetting
- Configuring routers and switches
- Network Address Translation (NAT)
Exercise Part 5:
- Configure a local network with multiple devices and set up NAT.
Session 6: Network Security
- Firewall basics
- VPNs
- Network security best practice
Exercise Part 6:
- Set up a firewall and configure basic rules for securing a network.
Module 4: Practical Applications & Troubleshooting
Session 7: Network Monitoring & Tools
- Monitoring tools (e.g., Wireshark, NetFlow)
- Performance analysis
- Common network issues and troubleshooting
Exercise Part 7:
- Use Wireshark to capture and analyze network traffic.
Session 8: Application Performance & Optimization
- Network latency and bandwidth considerations
- Optimizing network performance for applications
- Load balancing and failover strategies
Exercise Part 8:
- Implement a load balancing solution for a web application.
Practice Project: Building a Network for an E-commerce Application

Session 1-2:
- Designing the network architecture
- Mapping the OSI model to application components
Session 3-4:
- Setting up HTTP servers and configuring basic network services
- Implementing secure communication protocols
Session 5-6:
- Configuring network devices and setting up a secure network environment
- Implementing NAT and firewall rules
Session 7-8:
- Monitoring and analyzing network performance
- Optimizing network performance and implementing load balancing
