From Development to Research
• Sources of research topics
1.
Literature repository: minor improvement on existing or pseudo
problems
2. Development projects: feasible solutions on real problems
3. Industrial discussions: real problems but not necessarily feasible
solutions
• D(development)  R(research)
 Enabling resource: Linux
 Research is the non-trivial part within the development process.
 If I don’t know how to develop it, I would not research on it.
• Roadmap and footprints: cable TV networks (1996-1999) 
multi-hop cellular (1998-2000)  QoS (1998~2003)  deep
packet inspection (2004~2009)  traffic forensics (2008~)
 embedded benchmarking (2011~)  software defined
networking (SDN, 2013~)

Computer Networks: An Open Source Approach
considers why a protocol, designed a specific way, is
more important than how a protocol works. Key
concepts and underlying principles are conveyed
while explaining protocol behaviors. To further bridge
the long-existing gap between design and
implementation, it illustrates where and how protocol
designs are implemented in Linux-based systems. A
comprehensive set of fifty-six live open source
implementations spanning across hardware (8B/10B,
OFDM, CRC32, CSMA/CD, and crypto), driver
(Ethernet and PPP), kernel (longest prefix matching,
checksum, NAT, TCP traffic control, socket, shaper,
scheduler, firewall, and VPN), and daemon
(RIP/OSPF/BGP, DNS, FTP, SMTP/POP3/IMAP4, HTTP,
SNMP, SIP, streaming, and P2P) are interleaved with
the text.

“The exposure to real life implementation details in this book is phenomenal...
Definitely one of the better books written in the area of Computer Networks.” –
Mahasweta Sarkar, San Diego State University
“I have never seen a book giving such details on explaining the design and
implementation of such practical systems...Those open source implementations
are excellent demonstrations for practical networking systems.” – Fang Liu,
University of Texas-Pan American
“This is a solid textbook with strong emphasis on technical (implementation)
details of computer network protocols.” – Oge Marques, Florida Atlantic
University
“Written by RFC and open source contributors, this book definitely is an
authentic guide for network engineers.” – Wen Chen, Cisco Fellow
“Interleaving designs and implementations into the same book bridges the longexisting gap and makes this an ideal text to teach from.” – Mario Gerla,
University of California, Los Angeles
“The sidebars of Historical Evolution and Principle in Action make the reading
more enjoyable, while Performance Matters treat computer networking
quantitatively.” – H. T. Kung, Harvard University

The Internet of Things & M2M

Vision of Connected World
• Everything that can be connected will be connected
to the global Internet.
• These “things” form the “Internet of Things (IoT)” to
offer human smart services.
• The IoT involves “machine-to-machine (M2M)
communications” where machines (a.k.a. things)
interact with other machines or men to provide
services.
• Such a connected world greatly improves human life.
Major applications include smart home, smart grid,
connected car and eHealth etc.
2
Gaps in Achieving the Vision
• Lack of addresses and bandwidth has limited the
development of the IoT and M2M in the past.
• Most M2M is thus restricted to a limited, local area.
• With the widespread of mobile broadband and IPv6,
these gaps can now be overcome.
• It is predicted that on the planet earth there will be
50 billions of connected devices by 2020, each with
an IPv6 address.
• It is also predicted that in average, everyone of us
will be associated with at least 10 connected devices.

My work
• Nanoparticle assisted ultrasound therapy
(NAUT)
– Tumors collect more nanoparticles than regular
cells
– When exposed to ultrasound, cancerous cells
preferentially killed
– Work in collaboration with Academia Sinica
Results
BEAS-2B – normal cells; A-549-cancer cells
My work (continued)
– Dynamics and mechanism of effect is what?
• Spot heating? (Overall temperature didn’t change)
• Additional cavitation from nucleation?
– Safety of imaging with nanoparticles in body?
• Ultrasound levels were in diagnostic range
• Such range is safe without other items; but known to
create effects with microbubbles
• Nanoparticle assisted ultrasound imaging
– See nanoparticles or clusters of nanoparticles?
– With cancer-specific drugs, see tiny tumors?
Other planned projects
• Development of ways to • Behavior based
perform ultrasound CT

– Ultrasound CT produces
images with decreased
