Goal To Achieve: 
Dynamically Changing Buffer Size or Queue Size to Achieve Better Video or Gaming Quality

1. Setup a simple mininet Topology
2. Congest with TCP traffic
3. Adjust queues and buffers
4. Plot graphical results

Topology:

	Whole Topology:
	PC1 -- Internet -- Mininet -- PC2
	Mininet Topology:
	
                  ---Mininet---
                 |   h1    h2  |
		 |   |     |   |
