PROFESSIONAL EXPERIENCE Center For Computation & Technology (CCT), Louisiana State University, Baton Rouge, LA, USA Jan 2010 - Current Graduate Research Assistant CRON (Cyber-infrastructure of Reconfigurable Optical Networking environment), developed 10Gbps emulation based high-speed networking testbed CRON, NSF(award #0821741). Integrated 10Gbps Cisco N5020 switch, Myri10GE NICs, Anue 10G Emulators, NetFPGA and OpenFlow into CRON control framework. Modified FreeBSD and Linux kernels on the high-end servers to operate at 10Gbps bandwidth. Developed by C/C++, Perl, TCP/IP, SNMP, XML, LAMP, FreeBSD, Linux. GENI (Global Environment for Network Innovations) Federation, created python scripts to federate CRON as a ProtoGeni site into GENI framework. Demonstrated on GEC9, resource connection between CRON and BBN GPO Lab. Demonstrated on GENI conference 11 to 14, the Internet2 10G links connection between CRON and PlanetLab Central MAX. Developed by Python. High-speed Network Research, evaluated performance of high speed TCPs, queue management schemes and buffer sizing over 10Gbps networks. Solved the inter-protocol fairness problem in 10Gbps networks by developing approximate fair queue in Linux kernel. Also solve the high latency problem over high speed networks by integrating approximate fair queue with CODEL queue in Linux kernel. Developed by C/C++, TCP/IP, FreeBSD, Linux.
Google, Mountain View, CA, USA May 2012 – August 2012 Network Engineering Intern, Google Fiber QoS for Bruno (Google Fiber storage box and TV box) (using C in Linux kernel) o Developed functions in Bruno Broadcom driver to change the kernel variables at run time, which can save Bruno kernel developer huge amount of time without re-build the whole kernel. o Investigated Bruno multi-queue QoS issue after fine tuning the kernel variables. o Fixed the QoS issue by setting up the Bruno MoCA tx queue mapping. After fixing the issue, Bruno can always protects TV streams against TCP/UDP streams. o Fixed Bruno intermittent throughput issue by enlarging the non-priority queue size Bruno Platform Automation Test (using Python) o Setup testbed of automation testing for Google Fiber Bruno platform o Wrote python scripts with wrapped classes and functions to automate the testing process of Google Fiber Bruno platform, including networking features for Ipv4, Ipv6, DHCP, DNS, NTP, TCP, UDP, ICMP, IGMP, Multicast, and etc.
Alcatel-Lucent, Beijing, China March 2008 – December 2009 Member of Technical Staff 1 Remote Maintenance Tools (RMT), worked on a large business-critical client-server application Remote Maintenance Tool (RMT), which is used to configure, diagnose, test or monitor its peer components (CDMA2000/UMTS/GSM/LTE base stations) via sockets. Well trained with wireless knowledge and hands-on experience of wireless devices. Developed several features, including Frame Error Rate Auto Test, Optical Convert Module Loopback Auto Test and RF Calibration Auto Test. Developed by C/C++, TCP/IP, shell scripting, MFC, UNIX, VxWorks, SVN.
Samsung Telecommunications Research Institute, Beijing, China November 2007 – February 2008 Software Dev Intern Samsung CDMA Mobile Software, developed the optimization of software program on Samsung mobile embedded system, and tested GUI interface for Samsung GSM /CDMA/TD-SCDMA mobile phones. Good hands-on experience of mobile phones and mobile embedded system. Developed by C in windows mobile.
National Key Laboratory of Networking and Switching Technologies, Beijing University of Posts and Telecommunications, Beijing, China March 2006 – October 2007 Graduate Research Assistant Driver for Networking Devices, implemented the hardware driver for L2/L3 switches and routers on Broadcom switch chips and PowerPC CPUs. Developed the driver modules, including VLAN management, QoS, Rate Control, Port Mirror, etc. Solved the on board performance issue of Gigabit ports on the L2 Switch. Developed by C in Embedded RTOS. Protocols for Networking Devices, designed and implemented the MAC Layer protocols on L2 switch by going through the RFCs, including IEEE 802.1D Spanning Tree Protocol (STP) and GARP VLAN Registration Protocol (GVRP), improved the multiply VLANs support on STP, and solved the QoS issue by studying IEEE 802.1P. Developed by C in Embedded RTOS.
