Project Overview

Project Name: TCP maximum segment size (MSS) improvements
Student: Akash Mondal
Mentors: Mohit Tahiliani, Bhaskar Kataria, Vivek Jain

Project Goals: TCP MSS directly influences the size of an IP packet. And an optimal packet size can highly improve the throughput of a network. Thus, the goal of this project is to dynamically change the MSS of a TCP connection, which can be done by the following setups:
- Add Path MTU discovery support for IPv4
- Communication layer between l3 and l4 protocols to send PMTU updates
- Adapt TCP to support dynamic changes of the maximum segment size (MSS)

About Me: I’m a Master of Engineering student at Jadavpur University, Kolkata. I have an interest in application development and competitive coding. And I also love to contribute to open sources. I have developed several app development projects on the MERN stack. And I extensively use C++ and its powerful STL libraries for problem-solving related to competitive coding. I started working with ns-3 while doing my final year project of M.E. and eventually grew my interest in computer networks as well. Sometimes I draw random sketches and portraits during my free time, which I take as a hobby. I enjoy doing all my work listening to music because it boosts my brain, so I low-key consider myself a music lover too.

Milestones and Deliverables

Detailed Project Plan (will be continuously updated throughout the GSoC program duration)

Week 1

Duration: June 6 - June 12

Study about Layering, Router Specs, Storing & Purging PMTU from RFC 1191.
Understand different approaches to path MTU discovery (Packetization Layer Path MTU Discovery [RFC 4821], Classical Path MTU Discovery [RFC 1191]).

Week 2

Duration: June 13 - June 19

Understand the working of Packetization Layer Path MTU Discovery and Classical Path MTU Discovery.
List out the main differences between the two. link

Week 3

Duration: June 20 - June 26

Pros and Cons of Packetization Layer Path MTU Discovery and Classical Path MTU Discovery. link
