Project Report from the year 2017 in the subject Engineering - Computer Engineering, grade: 4.5, language: English, abstract: In this project, we describe FAST TCP, a new TCP congestion control algorithm for high-speed long-latency networks, from design to implementation. We highlight the approach taken by FAST TCP to address the four difficulties, at both packet and flow levels, which the current TCP implementation has at large windows. We describe the architecture and characterize the equilibrium and stability properties of FAST TCP. We present experimental results comparing our first Linux prototype with TCP Reno, HSTCP, and STCP in terms of throughput, fairness, stability, and responsiveness.



FAST TCP aims to rapidly stabilize high-speed long-latency networks into steady, efficient and fair operating points, in dynamic sharing environments, and the preliminary results are produced as output of our project. We also explain our project with the help of an existing real-time example as to explain why we go for the TCP download rather than FTP download. The real-time example that is chosen is Torrents which we use for Bulk and safe-downloading. We finally conclude with the results of our new congestion control algorithm aided with the graphs obtained during its simulation in NS2.
