Computer Networks - Congestion Control Analysis and File Sharing

TCP NewRenoPlus

Housed in newrenoplus/ is the Experimentation and Analysis of current TCP Congestion Control Protocols (CCPs) - Vegas, Reno, Westwood and Cubic.
Simulation was performed on the ns3-29 software.
The Congestion Window plots, the log files and packet captures for all the variations of experiments (varying Channel Rates, Application Rates) are stashed in the results/ subdirectory.
To run, execute run.sh, which handles all parameter selection and topology selection.
Add TcpNewRenoPlus.cc and TcpNewRenoPlus.h to ns3's TCP files to use it for Congestion Control.
tcp_protocols.pdf presents the complete analysis on the performance of these protocols.

Code housed in PSP directory.
An attempt at obtaining the best-of-both-worlds benefits from P2P and a fully Client-Server File sharing.
Objective : File sharing between nodes, node queryies caches for file, if not in cache then request forwarded to other nodes.
A Cache, housed in lrupart[12].py is used to aid the distribution as well.
We experiment with using TCP and UDP for the Data and Control Planes, as well as the optimum Caching required.
A complete Analysis of performance is done in analysis.pdf.
