This project involves designing and configuring a Wide Area Network (WAN) for a mock bank branch. The setup includes:

• Three LANs (one with two VLANs)
• Cisco routers and switches
• IP addressing, VLANs, Inter-VLAN routing, static routing, and SSH security configuration

• Software: Cisco Packet Tracer 8.2.1 or later
• Skills Required: Networking concepts, Cisco IOS configuration, subnetting, VLANs, routing

1. IP Addressing Scheme: Subnet the 172.16.10.0/16 network into seven subnets.
2. VLANs & Trunking: Create VLANs (Management, Marketing, Accounting) and configure access/trunk ports.
3. IP Address Assignment: Assign subnets and IPs to network devices.
4. Inter-VLAN Routing: Configure router sub-interfaces for VLAN communication.
5. Static Routing: Set up static routes and default routes.
6. Security Settings: Secure routers and switches with user accounts, encrypted passwords, and SSH access.
7. Testing & Troubleshooting: Verify configurations with ping, show commands, and troubleshooting steps.

• Packet Tracer File: Complete network topology with saved configurations.
• Documentation: Addressing table, configuration steps, and screenshots.

Develop a client-server application using sockets in Python, C/C++, or Java. The project consists of two implementations:

1. TCP Socket Server: Receives strings from clients and returns the reversed string.
2. UDP Socket Server: Same functionality but using UDP.

• The server should handle at least 5 simultaneous clients.
• Clients can send multiple strings, and the server should respond accordingly.
• Both client and server should display sent/received messages.
• The server must run on a separate machine from the clients.

• Source Code: Well-commented code for both TCP and UDP implementations.
• Design Document: Overview of program architecture, design decisions, and improvements.
• Testing Report: Description of test cases, execution traces, and known limitations.
• Build & Execution Guide: Instructions on compiling and running the program.

# Run the server
python tcp_server.py

# Run a client
python tcp_client.py

# Run the server
python udp_server.py

# Run a client
python udp_client.py

For multiple clients, open separate terminals and execute the client script multiple times.
