The systems and networking group at
UCSD engages in a wide range of experimental and theoretical
research. Our current projects span fault-tolerant networks and
systems, high-speed router design, storage system design, network
measurement and traffic analysis, peer-to-peer system design, network
security, mobile code architectures, high-performance cluster
computing, and wireless networking. Our group consists of nine core
faculty, four affiliated faculty (in a broad range of areas
including security, machine learning and programming languages) and
over 60 graduate students and research staff. Our work is
well-supported through generous funding from government and industrial
sources.

Recent Alumni
(12/18/08) The 2010 NSDI notifications
are out, and five papers with UCSD authors were accepted
(down one from last year's record of 6). Congrats to Mohammad, Siva, Barath, Nelson, Terry, Harsha, Amin, George and all their collaborators at Washington, Harvard, Wisconsin and Microsoft!

(9/2/09) Mikhail
Afanaysev defended his thesis today. Mikhail
leaves the group for Brisbane, Australia, furthering SysNet's global
expansion plans; SysNet alums now inhabit four continents. Good luck, Mikhail!

(8/31/09)
Hot on the heels of Colin arrives Delaney Grace Vahdat, mustering 8
lbs 8 ozs and measuring 20.25". Congrats Suzanne and Amin!

(8/20/09) Another SIGCOMM paper getting attention, this time by UCSD alumn Ramana Kompella, along with our own Kirill, Alex and George. In it they describe efficient router-level techniques for measuring packet loss and latency. Read more about it in Ars Technica. Congrats everyone!
|
(8/18/09) Congrats to the PortLand team — Radhika, Andreas, Nathan, Nelson, Pardis, Siva, Vikram, and Amin — for all the attention they've been getting on their SIGCOMM '09 paper on L2 support for 100,000 port switches. See coverage in Network World, again in Network World (this time setting up a false battle with Microsoft), and Slashdot among others. Only 99,900 ports to go!

(8/10/09) Stephen Checkoway, in collaboration with Hovav
Shacham, Brian Kantor and their co-authors from Michigan and
Princeton, recently demonstrated a practical attack against the AVC
Advantage voting machine — absent any access to source code and
overcoming a hardware architecture that prevents code execution from
DRAM. More info can be found in the Jacobs School press release here or in their EVT'09 paper here.

Christine and Alex are
the delighted new parents of Colin Luis Alvarado-Snoeren, a bouncing
new gadget for the home weighing in at precisely 4.00 kilos.
