Ho-Yu LAM

Hi! I am Ivan. I am a software engineer in the San Francisco Bay area. I got my Ph.D. in Electrical Engineering at The Polytechnic Institute of NYU in August 2013. I was a research fellow at the High Speed Networking Laboratory (HSNL). My research covered software defined networking, datacenter networks and network security. I worked as an Intern at Huawei Technologies, Santa Clara, from July to December 2010. I obtained my BEng degree in computer engineering and MPhil degree in computer science at the Hong Kong University of Science and Technology (HKUST).

Prof. H. Jonathan Chao is my PhD supervisor and I finished my MPhil thesis and undergraduate final year project under the guidance of Prof. Dit-Yan Yeung.

I am interested in network security and policy management research. I am currently designing a network security policy enforcement architecture (HSA) for data center networks. The project aims at facilitating very flexible and dynamic middle box placement and traversal. As part of the project, I am designing an algorithm and data structure for traffic-aware packet classification policy optimization. Before exploring along this direction, I have investigated various research topics such as the problem of email Spam, Spam over Internet Telephony (SPIT), Peer-to-Peer (P2P) network security and potential applications exploiting P2P networks.

Back in HKUST, I have worked on three major research projects since my final year of undergraduate study. I built and maintained a network testbed composed of GNU/Linux based servers, routers and PCs for a projects on Distributed Denial of Service involving three major universities in Hong Kong. During the second year of my MPhil study, I served as a teaching assistant for an undergraduate course on Algorithms and Data Structures. I delivered weekly tutorials and involved in the design and grading of all the assignments and exams.

Research interests

Network Security and policy management, security architecture for data center networks and cloud computing.

Hybrid Security Architecture is currently my main research project.

Here is a list of upcoming relevant research conferences.

I maintain a blog for technical notes on Linux administrations and configurations.
