# ns3-sim
An ns3 simulation script to compare various TCP variants under congestion
### Install Instructions:
Requirements:
* ns3(3.26)
Steps:
* Install ns3 and put ns3.cc in the scratch directory.
* Run the script using ```./waf --run "ns3"```
* For command line options and help, ```./waf --run "ns3 --PrintHelp"```
### Topology
n0 ----------- n1
Topology consists of two nodes N0 and N1 connected by a link of bandwidth 1Mbps and link delay 10ms. We are using a drop-tail queue at the link.
### Simulation
There is a TCP agent at N0 which creates FTP traffic destined for N1. There are 5 CBR traffic agents of rate 300 Kbps each at N0 destined for N1.
The timing of the flows is as follows:
* FTP starts at 0 sec and continues till the end of simulation
* CBR1 starts at 200 ms and continues till end
* CBR2 starts at 400 ms and continues till end
* CBR3 starts at 600 ms and stops at 1200 ms
* CBR4 starts at 800 ms and stops at 1400 ms
* CBR5 starts at 1000 ms and stops at 1600 ms
* Simulation runs for 1800 ms
