Ensim Corp. Co-founder, CTO, General Manager, and
Director
June 1998-July 2003
Ensim’s Operations Support System software allows Internet
service providers to scalably and profitably host applications, primarily websites,
on behalf of small to midsize enterprises. Ensim raised over $85 million in
venture funding from venture capital firms such as New Enterprise Associates
and Worldview Ventures. From a handful of employees and a tiny office in
Ithaca, NY Ensim has grown to 150 employees in the US and India. Ensim software
today hosts over 750,000 websites and both its revenue and market penetration
are growing at an exponential rate.
As co-founder I was involved with every aspect of Ensim’s
operations and at every stage in its development. Over the years my
non-technical roles included Business Unit Manager with profit and loss
responsibility, Product Line Manager, Sales Engineer, Test Automation Engineer,
Director of Quality Assurance, and Director of Information Technology. I also
served as a media spokesperson for Ensim, appearing on local, national, and
international television and print publications.
My technical role at Ensim was to provide architectural
guidance to all of Ensim’s products. In this role, I augmented my networking
background with a hands-on understanding of operating system design and
implementation, enterprise software design, and web-services based distributed
system architecture. I helped to architect a world-class product line supported
by 17 patent applications, of which I am an inventor or co-inventor on 13
applications.
GreenBorder Technologies Inc. Co-Founder October 2000-
GreenBorder’s software allows enterprises to
securely share information. I came up with the idea that led to the formation
of the company and helped raise its first round of funding of $2.4 million (the
company subsequently raised $12 million in August 2002). I also contributed to
the design of the company’s product, its market positioning, and its patent
strategy. Currently I do not have an operational role in the company.
Cornell University Associate Professor
August 1996 – June 1999
I was
instrumental in initiating a research and teaching program in computer
networking at Cornell. In 1996, I created a graduate course on networking based
on my textbook and taught the course in 1997 and 1998, each time to over 80
students. As part of the course, I led student teams in designing and
implementing large-scale research projects (described in more detail below). I
also taught a graduate course on systems, and introductory courses on computer
architecture and logic design. In
recognition of my work, I was awarded the Fiona
Ip Li '78 and Donald Li '75 Excellence in Teaching Award in 1998.
I founded
and led the C/NRG (Cornell Network Research) group, working in the areas of
Network Performance Management, Internet topology discovery, and Computer
Telephony Integration. In Spring 1999, C/NRG consisted of seven Ph.D. students,
one staff programmer, six masters students, and four undergraduates.
In addition
to teaching and research, for two years I was part of the CRUSADE group that
brought together faculty and staff from Cornell Information Technologies, Computer
Science, the Johnson School of Management, and the Ithaca City Council to
accelerate the introduction of broadband technologies to Ithaca. I also helped
to run the Computer Science departmental science fair in 1998 and 1999.
Courses taught:
1. “Engineering Computer Networks,”
Aug-Dec 1996. In the course project, three groups of 27 students each
implemented a full E-Commerce system including public key infrastructure, a
storefront, cluster-based encryption, persistent file storage and a transaction
system.
2. “Advanced Systems,” Jan-May 1997.
3. “Engineering Computer Networks,”
Aug-Dec 1997. In the course project students implemented the HTTP (web), LDAP
(directory), DNS (Internet name service), and SMTP (email) protocols from
scratch on a simulator as well as in Unix.
4. “Introduction to Digital Systems and
Computer Organization,” Jan-May 1998.
.
5. “Engineering Computer Networks,”
Aug-Dec 1998. In the course project three groups of 30 students each built a
complete Computer Telephony Integration system including Voice-over-IP,
Dialogic voice board management, integration with a Lucent Definity switch,
multi-party conferencing, fax-to-email, and email-to-fax. This software, later
rewritten and released into the public domain by my research group, was used at
Columbia, AT&T Labs and University of Kentucky as the basis of their work
on Computer Telephony Integration.
6. “Introduction to Digital Systems and
Computer Organization,” Jan-May 1999.

AT&T Bell Laboratories, Member of Technical Staff August
1991‑August 1996
I was one of the 60 Members of Technical
Staff at Center 1127. I primarily
participated in the design, implementation, testing, and performance tuning of
Xunet II, a wide‑area high‑speed ATM network testbed, and IDLInet,
a Personal‑Computer‑ based ATM LAN that provided native‑mode
ATM connection.
As part of the Xunet team, I participated in
the design, implementation, testing, performance tuning, and field support of
almost all the components in the Xunet II edge router that provided IP- over-
ATM service and FDDI-to–ATM interoperability. This included firmware that
ran on a network interface card processor, the corresponding Unix device
driver, the protocol stack, an ATM signaling daemon, and kernel software for
supporting native-mode ATM applications. In addition to hands-on software
development and maintenance of a large system of software, I helped guide more
than twenty summer students in their use of the network. I ran some of the
earliest (1993) and largest (twelve simultaneous video feeds) videoconferences
over an IP network. I added Quality of Service (QoS) support to signaling, and
helped design a scheduling architecture to allow per-virtual circuit QoS for
Constant Bit Rate, Variable Bit Rate, and Available Bit Rate virtual circuits.
As part of the IDLInet team, I rewrote the
entire data path of the protocol stack, designing and implementing new
algorithms for flow control, buffer management, scheduling, and packet
retransmission. I also guided a student in reverse-engineering a device driver
for the FORE Systems 200-series network host-adaptor, porting all the Xunet
router software to IDLInet, and performance tuning.
Over a period of five years, my colleagues
and I investigated several areas in traffic management and feedback congestion
control and helped apply these principles to the design of a traffic management
scheme for Xunet II. My student Matthias Grossglauser and I did a detailed
analysis of CBR traffic over tandems of servers, and then, with David Tse,
showed that a Renegotiated CBR service is well-suited for carrying traffic that
exhibits burstiness at multiple time scales. Prof. Huzur Saran at IIT Delhi and I formalized and investigated
optimal holding time policies when carrying IP over ATM networks.
Finally, I did some work in telepresence and
low-bitrate video encoding. With Alan Kaplan, I combined an efficient facial
animation system and a text-to-speech system for `zero-bitrate' video. Our work
serves as the basis for the ‘speech-assisted video interpolation’ component of
the MPEG 4 video compression standard. I was also part of a team that built a
toy car that could be driven over the Internet using real-time video, some of
the earliest work on telepresence over the Internet. This work was presented at
the Liberty Science Center in Newark, New Jersey, as part of a public lecture
series in 1995.
In addition to research, I wrote a
graduate-level textbook on an engineering approach to computer networking.
Published by Addison‑Wesley Longman in May 1997, it has sold over 20,000
copies and is being used as a course textbook at many leading universities
around the world.

SOFTWARE
REAL: An early packet level public-domain network simulator.
Extensive support for research in flow and congestion control. First released
as v2.0 in 1989; v 5.0 released in 1997. Installed at over 1500 sites in over
50 countries. I was solely responsible for design, implementation, packaging,
release, maintenance, and documentation. The REAL simulator later became the
basis for the very widely used ns-2 simulator.
XUNET II: The first wide area ATM network.
Responsible for design, implementation, testing, and performance tuning of host
adaptor firmware, device driver, signaling extensions (with Rosen Sharma), and
master source tree maintenance (with Pat Parseghian). The source code was
available for research use, at no charge, at all Xunet II university sites.
IDLInet: The first Personal-Computer based ATM LAN. The software was implemented
in DOS, Brazil, FreeBSD, and Linux kernels with Fore and Zeitnet hardware.
Responsible for top-level design, architecture, kernel-level debugging, and
coordination of implementation between IIT Delhi and AT&T Bell
Laboratories. This source code was licensed at no charge to academia.
ITX: A Java-based computer telephony platform. The software was
first built as part of a course on computer networking, then refined by a team
of six students in Spring 1999. This platform implements the basic building
blocks for computer telephony: voice-over-IP, signaling, dynamic directory
resolution, and CTI gateway management. The source code is freely available and
has been used by researchers at Columbia University, AT&T Labs, and U.
Kentucky.
I hold patents and have filed patent
submissions on a wide variety of systems issues, ranging from cryptography to
cluster computing, and from server virtualization to telecommunications
services. Several of these have had real-world impact.
