CS619 Final Project Fall 2019 - Performance Improvement in DCTCP
Project Domain / Category
Abstract / Introduction
Web applications are gradually shifting into cloud environments. These cloud
services are hosted on huge scale computation and storage infrastructures called
data centers (DC) (e.g. Google’s data center, Facebook’s data center etc.). In a largescale data center, hundreds of thousands of servers are connected through switches
in a symmetric topology. A data center network (DCN) interconnects all the data
center resources. Data Center TCP (DCTCP) is a modified version of TCP which is
proposed specifically for intra-DCN communication .
DCTCP, although, performs significantly better than TCP in data centers but still
suffers from performance issues; DCTCP incurs significant packet drops due to bursty
flow arrivals (many-to-one communication).
This project aims to:
i) identify the causes of packet drops in the event of bursty arrivals,
ii) propose solution(s) to mitigate the packet loss issue.
The problem will be studied by simulating DCN environment in network simulator
ns-2. In addition, the proposed solution will also be implemented in ns-2. Working
in ns-2 requires:
i) understanding of basic commands of Linux operating systems (for ns-2 installation
and running purposes),
ii) good programming skills in C++ (for simulating the DCN environment and making
the required changes in DCTCP),
iii) programming in TCL (for writing simulation scripts),
iv) understanding of AWK command (for trace text processing),
v) understanding GNUPLOT command (for drawing graphs).
