Experiments plot 1: CAIDA trace characteristics

[divyapathak24]

Question: What is the behavior of different normal scenarios for CAIDA traces? Why: To label the instances and use it for training the model Plot: Plot CDF of % retransmissions and identify the boundaries for normal, congestion/pkt loss and link failure

Todo:

• 10 CDFs for 10 sample pcaps (top prefix) -- the cdf should capture ret% distribution --> analyze each cdf plot and get the boundaries for normal, congestion, link failure and tag the boundary details to respective plot (update the plots in slides).

The plots for the 10 pcaps have been created and will be presenting those in the meeting, currently looking into ways to save interactive plots. Once I look into saving the plots will add them to the repository if required.

Observations Of the Plots :

• The below plots are CDF plots with Retransmission % on the X axis and its respective density on the y axis.
• The data points for the plots are the retransmission logs of the respective pcaps, with the retransmission % being logged every 80msec
• Since each pcap is roughly 60 sec their are roughly 750 data points for each pcap.

• Seems to be a close to ideal pcap, with a max retransmission % of 1.56.
• Around 98.6% <= 0.
• 100% <=1.56

• Has around 70% of data points < 5 retransmission %.
• A minority of around 20 -30 % of data points between 5-15 % retransmission.
• Around 1 % of data points > 15.

• Around 85% of data points lies < 5.
• Roughly 15 % of data points lies between 5-10.

• Slightly less than 60% of data points lies < 5.
• Around 35% of data points lies between 5-10.
• Around 1.2% data points lies > 15.

• Around 25% of data points lie < 5 .
• Around 70% lies between 5-15.
• Around 2.3 % of data points lie > 15.

• Around 80% of data points lie < 5.
• Around 18% of data points lie between 5-15.
• Around 2 % of data points lie > 15.

• Around 80% of data points lie < 5.
• Around 16% of data points lie between 5-15.
• Around 4 % of data points lie > 15.

• Around 80% of data points lie < 5.
• Remaining 20% of data points lie between 5-10.

• Around 20% of data points lie < 5.
• Around 65% of data points lie <10.
• Around 7% of data points lie between 10-15.
• Around 8% of data points lie >15.

• Around 83% of data points lies < 5.
• Roughly 17 % of data points lies between 5-10.

Cumulative Graph :

The Cumulative graph is plotted by considering the data points from all the pcaps.

• Around 70% of data points lie < 5.
• Around 23% of data points lie between 5-10.
• Around 5% of data points lie between 10-15.
• Around 2 % of data points lie >15.

Final Conclusion :

We can divide the behavior into the following categories:

• Normal : Have 0-5% retransmission percentage.
• Congestion : Have 5-15% retransmission percentage.
• Link Failure : Have >15% retransmission percentage.
