Welcome to the Implementation-of-Eifel-Retransmission-Timer-ns-3 wiki!

Task 1

• Consulted the course instructor to get started with the understanding of Eifel-Retransmission-Timer.
• Gone through getting started of ns-3.
• Successfully installed, initialised and configured git in the local machines.
• Updated the local repository with ns-3 source code.
• Synchronised the remote Github repository with the local repository.

Task 2

• Studied how to compile and run programs on ns-3
• Started reading the paper on Eifel-Retransmission-Timer.
• Discussed the possible implementation mechanisms to follow.
• Started studying various component required for Eifel-Retransmission-Timer.
• Analysed the already implemented RTO in ns-3

Task 3

• Closely examined the default implementation of RTT in ns-3.
• Generated the default RTT & RTO graphs and analysed the possible modifications.
• Started meeting the course instructor and discussed our idea of implementation.
• Started implementation by making changes in rtt-estimator.cc and tcp-socket-base.cc files

Task 4

• Added flag for enabling Eifel-Retransmission-Timer in tcp-variants-comparison.cc
• Consulted the instructor regarding the graphs generated and possible modifications are done.
• Work in progress.

Task 5

• Added Flight variable and RttSamplingRate for the gain calculation
• Drew the RTT, RTO graphs for different values of RttSamplingRate.
• Found the reason for the doubling for RTO value at time instant t = 2.6s.
• Fixed the lastRtt variable calculation which is used in RTO formula.
