Curriculum Vitae for Lorenzo Colitti
Overview
I am a networking specialist with a Ph.D in network management, topology
discovery, visualisation, and measurement.
My background combines methodological and theoretical problem analysis skills
learned in academia with thorough technical knowledge of networks and systems
from my research and my experience as a system architect and administrator.
I am looking for a position where I can apply these skills to challenging and
varied problems in a stimulating environment while delivering products and
services that will be used in the real world, thus combining the intellectual
statisfaction of academia with that of seeing my work reach the
hands of users.

Ph.D in Networking
I was awarded a fellowship for a doctoral programme at Roma Tre
University in November 2002 and obtained a Ph.D on April 6 2006.
My Ph.D thesis, Internet Topology Discovery Using Active Probing,
can be found online.
Research interests
During my Ph.D I carried out research on the following topics:
- IPv6-in-IPv4 tunnel discovery methodologies, their application to the current IPv6
Internet, and the impact of tunnels on the global network.
- BGPlay, a system for visualising routing changes in the IPv4 and IPv6 Internet.
- Active BGP probing methodologies for interdomain topology discovery by manipulating routing announcements.
- Evaluating the effects of anycast on DNS root name servers.
Involvement in the 6net project
As the University's contact person for the EU-funded project
6net, I was involved both in project
accounting and work package meetings and in technical work. Non-research
contributions include:
Teaching
Enterasys Specialist Switching
courses on routing support in the N and E series (2006).- Interdomain Routing (BGP configuration, policies, registries) course for
Telecom Italia Learning Services. (2004)
- IPv6 tutorials for the
users of the Italian research network GARR and for master students.
(2002—2003)

Master’s Degree
From 1995 to 2002 I read Electronics Engineering at Roma Tre University
in Rome, obtaining a Laurea (equivalent to M. Sc.) with a final mark of
110/110 cum laude. My thesis
[pdf]
was on the study of methodologies for the automatic
discovery of network topology in mixed IPv6-IPv4 networks. Other University projects include:
- Implementation and management of the university's IPv6 network. (2001—)
- Partial implementation under Linux of the draft IETF IP-version independent MIB (2002).
- Design and implementation of
a generic framework for distributed computing in Java and RMI and
application of the system to distributed calculation of fractals (2000).
- Design and C++ implementation of a web application for the graphical comparison of telephone call prices (2000).
- Analysis of the University WAN network: topology, protocols, and performance (1998).
Google Summer of Code Project
I participated in the 2005 Google Summer of Code project, working with the GNOME foundation on improving GNOME login time. Many in the GNOME community appreciated my work. A full report is available on the GNOME web site.
Employment experience
2006—: Network Engineer, Google
2003—2006: Network Engineer, RIPE NCC
From 2003 to 2006, in parallel with my Ph.D, I worked in the New Projects group at
RIPE NCC in Amsterdam, first as
an intern and then as a part-time and now full-time employee. Projects I have worked on include:
- Extension of the RIPE NCC Routing Information Service (RIS) to support IPv6.
- Integration of BGPlay with the RIS.
- Evaluating the effects of anycast on the K-root DNS server.
- Support of 32-bit AS numbers in the RIS.
2000–2002: System and network administrator, xmedia Srl
From 2000 to 2002, in parallel with my master’s degree, I worked as a
system and network administrator at xmedia, one of the first web
agencies in Italy (since dissolved). There, I:
- Administered the company's network and Linux/Solaris servers (~60 users, ~20 servers)
- Defined and implemented routing, security, firewalling, backup, and monitoring policies
- Administered Oracle and PostgreSQL databases
- Wrote technical documentation for business proposals of custom services
- Designed and implemented:
- The company's Linux-based web hosting platform and virtual domain email service
- A proof-of-concept pay-per-view streaming video solution based on Windows Media

Non-professional Experience
BBS Management
From 1996 to its shutdown in 1998 I was involved in the management of
the largest amateur BBS in Rome, Antanisoft Group Research
, with
hundreds of users. Together with the BBS's founder I implemented a
series of support programs, including a watchdog that guaranteed the
operation of the BBS 24 hours a day.
Involvement in open-source projects
Since 2001 I have been contributing to the
Mozilla project, which created the
Firefox and Thunderbird applications. My contributions to the project include
IMAP quota support, IPv6 improvements, improvements to the spam filter, and
miscellaneous bug fixes and QA. I am one of the developers of the
Flashblock extension for Firefox.
In 2001 I added OAM cell support to the Linux kernel driver for the
Alcatel SpeedTouch USB ADSL modem to enable interoperability with Cisco
routers with the oam-pvc manage setting. I have also contributed code
and bug fixes to various open-source applications including
quagga,
Net-SNMP,
User-Mode Linux,
wpa_supplicant, and
Software Suspend 2.
Hobbies
Photography, film,
languages, travelling,
cooking.
