Network Packet Processing Simulation (C++)

This is a small C++ console project I made while learning about enums and basic C++ programming. The program simulates how different types of network packets (like DATA, CONTROL, ERROR, etc.) are processed and validated using simple logic.

What does it do?

• Creates several example network packets with different types and protocols (like TCP, UDP, HTTP, etc.).
• Shows the details of each packet before and after validation.
• Validates each packet to check if it is valid or invalid, based on its type and protocol.
• Prints the results to the console, so you can see how the status of each packet changes.

Example Output

When you run the program, you’ll see output like this:

	=== Packet ===
Packet Type Name: DATA
Protocol Name: UDP
Status Name: PENDING
	=== Packet ===
Packet Type Name: DATA
Protocol Name: UDP
Status Name: VALID
---
	=== Packet ===
Packet Type Name: CONTROL
Protocol Name: TCP
Status Name: PENDING
	=== Packet ===
Packet Type Name: CONTROL
Protocol Name: TCP
Status Name: VALID
---
	=== Packet ===
Packet Type Name: UNKNOWN
Protocol Name: TCP
Status Name: PENDING
	=== Packet ===
Packet Type Name: UNKNOWN
Protocol Name: TCP
Status Name: INVALID
---
	=== Packet ===
Packet Type Name: ERROR
Protocol Name: HTTP
Status Name: PENDING
	=== Packet ===
Packet Type Name: ERROR
Protocol Name: HTTP
Status Name: VALID
---
	=== Packet ===
Packet Type Name: GROUP
Protocol Name: IGMP
Status Name: PENDING
	=== Packet ===
Packet Type Name: GROUP
Protocol Name: IGMP
Status Name: VALID
---
	=== Packet ===
Packet Type Name: RESOLUTION
Protocol Name: ARP
Status Name: PENDING
	=== Packet ===
Packet Type Name: RESOLUTION
Protocol Name: ARP
Status Name: INVALID

Why did I make this?

I wanted to practice using enums, classes, and simple validation logic in C++. This project helped me understand how to use enums for different categories (like packet types and protocols) and how to write basic class methods.

How to Run

1. Make sure you have a C++ compiler (like g++) installed.
2. Compile the code:

   g++ src/mainNetworkPacket.cpp src/fns_Packet.cpp -I include -o network_packet_sim
   

3. Run the program:

   ./network_packet_sim
