A Report On The Network

Good Essays

In this section, we will see the two networks constructed in Mininet and the flows running through the network
Flows:
1. A total of 12 simulations were run through the network. Flows were generated between hosts using the tool D-ITG.
2. Traffic generation:
D-ITG is used for generating traffic in the network. Random hosts and clients are selected for sending traffic. To get sufficient delay in the network the link is used up to 100% in case of heavy traffic, around 70% for medium traffic and 20% for low traffic. The receiver logs are registered for each flow. Flows nature is UDP as UDP does not re-attempt to send a dropped packet. The packet size is fixed to 1024 and number of packets send per second can be changed depending on the traffic requirement.
The following tables give the details of each flow which were simulated for network 1.
The network was created in Mininet. It consists of 12 hosts and 8 OpenV switches. It uses the external controller which is selected in Mininet python code.
Network 2 is constructed in Mininet. It is a partial tree structure with 11 switches and 12 hosts. External Floodlight controller is connected to the Mininet network using python code. The controller is set in a different Virtual machine.
Each KQI will be analyzed for all three algorithms on both the network.
1. Average Delay:
The best performing algorithm for high traffic flows is a latency based algorithm. It gives a minimum delay of 1.845 sec which is 28% lower than the delay observed
