I
joined the Department of Computer Science at the University of Virginia
in Aug 2003. My Ph.D. research was on
bandwidth-sharing algorithms and control plane design of dynamic
connection-oriented networks, under the direction of Professor Malathi
Veeraraghavan. Before joining
the University of Virginia, I
received my Bachelor and Master degrees in Computer Science from Shanghai
Jiao Tong University, China.
I received my Ph.D. in Computer Science in 2008, and now I am with
Yahoo! Inc.

Software
packages I developed for the CHEETAH project.
- CHEETAH
Control Plane Module (CCPM) is a software package that serves as an
external GMPLS engine for Ethernet switches. It is designed to enable
non-GMPLS switches to participate in the dynamic end-to-end circuit
setup. It consists of two main components, the OSPF-TE routing module
and the RSVP-TE signaling module. It supports Ethernet switches from
major vendors such as Dell, Force10, and Foundry. This particular build
is for Force10 E600 switches deployed in Internet2 HOPI network. (download)
- CHEETAH
Client System Agent (CCSA) is a software package to enable end hosts to
initiate circuit setup requests. It is based on the CHEETAH end-host
RSVP-TE client developed for Sycamore SN16000 switches. It consists of
two daemons, RSVPD and cheetahd,
and a tool called circuit-requestor, with which end users can setup and
release circuits manually. It also provides APIs so that it can be
integrated into any software that wants to automatically setup and
release circuits. The main extension of the CCSA is the support of L2SC
switching, i.e., the support of VLANs.
With this support, an end host can simultaneously have multiple
circuits to the same or different remote end hosts. (download)
- CHEETAH
RSVP-TE client for Sycamore SN16000 is a software package developed to
enable end hosts to initiate circuit setup across the CHEETAH network,
which has Sycamore SN16000 switches as the backbone. It consists of two
daemons, RSVPD and cheetahd,
and a tool called circuit-requestor, with which end users can setup and
release circuits manually. It also provides APIs so that it can be
integrated into any software that wants to automatically setup and
release circuits. This software is compatible with SN16000 version
7.6.2. (download)
