Academic Erasure Code Friendly TCP, UCSB (October 2011{February 2012)
projects Recent advancements in network coding technologies have made retransmission of
packets unnec-
essary. However, the widely deployed TCP protocols reliability mechanism enforces
retransmis-
sions at the transport layer. In addition, a TCP retransmission initiates an aggressive
congestion
window reduction response in TCP. In this project we shall modify the Linux kernel TCP
imple-
mentation to eliminate the enforced retransmission of lost packets. This modification
will defeat
TCP's congestion control mechanism causing it to compete unfairly with other TCP flows.
To
overcome this drawback we will implement a Linux pluggable congestion control algorithm
that
is able to function without retransmissions and is robust to non-congestion related
packet loss.
The TCP implementation will interoperate with standard sender side TCPs such as those
used
by large content providers.
Receiver Driven Rate Adaptation, UCSB (June 2011{Sept 2011)
The TCP protocol was designed to work best in environments with a small Round Trip Time
(RTT) and zero non-congestion related packet loss. In this paper we use multi-streaming
HTTP
flows to achieve superior slow start characteristics and robustness to non-congestion
related packet
loss. Multi-streaming TCP competes in an unfair manner with other flows in the bottleneck
router.
To overcome this drawback we implement a novel application layer fairness (congestion
control)
mechanism. We demonstrate the performance improvements of our proposed system through
both
emulation and deployment on a wireless mesh network in South Africa.
Work
Research intern, Aerospace Corporation (June 2010{Sept 2010)
experience
Designed an emulation system using techniques described in academic literature. This
ground-space emulation system will address the requirements for ground segment emulation
at high speed and fidelity, as well as be integrated with existing space link emulators.
Research intern, Citrix Online, LLC (June 2009{Sept 2009)
Bandwidth shaping, modeling, and adaptivity modules research. I developed these prototype
modules and conducted experiments to measure the quality of customer experience with the
next G2M product.
Daniel Havey 2
Research intern, Santa Barbara Labs, LLC (May 2008{May 2009)
Satellite network studies in conjunction with Lockheed Martin. Supported production of
white paper deliverables for the Air Force's TSAT Mission Operations System (TMOS)
project.
Supported the design and implementation of a high-fidelity emulation testbed to examine
the behavior of mobile IPv6 satellite networks
Teaching Assistant, University of California in Santa Barbara (Fall 2006{Spring 2008)
Held weekly classes for 10{20 students to provide additional detail not available in
lecture.
Held weekly o ce hours to answer questions and help students prepare for tests
Designed projects and homeworks for the students
Publications Refereed Conferences and Workshops
Software Time Division Multiple Access (TDMA) Scheduler for High-Fidelity Satellite Emu-
lation Testbed (HSET), The TDMA Scheduler is a component of the HSET testbed that was
delivered to Lockheed Martin as part of the TMOS project.
Scientist's Digital Notebook, This application is designed to simplify the image
annotation
process. It allows researchers to create meta-data required by the bio-image database. It
can
also update, print and upload existing information. It was delivered to the Center for
Bio-Image
Informatics in 2005 and is currently in use by biologists around the world
Satellite Mobility Model for Qualnet, This tool was developed in 2006 and provides
accurate
tracking of satellites in the Qualnet network simulator. It was released as open source
software
and is being considered for inclusion in Qualnet
