Software
Development
- The SELFIS tool: Designed
and implemented the SELF-similarity
analysIS
software tool. SELFIS is a java-based tool
for the analysis
of the self-similar and long-range dependence properties of time-series with
focus on networking.
It has
been downloaded over 600 times and is in use by researchers spanning various
disciplines and institutions.
(URL: http://www.cs.ucr.edu/~tkarag/Selfis/Selfis.html.)
- BLINC: Designed and implemented the BLINd Classification tool, a multilevel
transport-layer methodology to classify
Internet
traffic flows according to the applications that generate them without the
knowledge of port numbers
or the use
of payload signatures. BLINC was implemented in C++.
- PTP:
Design
and implementation of the P2P
Traffic Profiling tool. The PTP
tool is a methodology for the identification
of P2P
file-sharing traffic at the transport-layer without the use of payload
signatures and is implemented in C++ and Python.
- Peer-to-peer file-sharing and
application-specific protocol dissectors:
Reverse-engineering, design and implementation
of payload
signature-based traffic identification of the nine most popular file-sharing
peer-to-peer networks
(Kazaa, Gnutella, BitTorrent, eDonkey, Ares, WinMx, OpenNap, Soulseek, MP2P).
Identification of the traffic of the majority
of Internet
applications (web, streaming, ftp, chat, mail, news, gaming, etc). Implemented
in C/C++ on top of the
CoralReef Internet
Traffic monitoring software suite.
