Senior Research Engineer, April 2004 - Present - Collaborate with various faculty members at the University of Michigan on research projects - Led the design and development of a software tool called Flamingo to visualize and explore Internet traffic data based on netflow. This also involved working with and guiding student interns in the development of this project as well as various presentations and demonstrations. The software developed is currently in trials by various network operators. - Responsible for the design and architecture of the data collection and storage system for the DHS funded PREDICT project - Led the design and development of a software tool called BGP-Inspect to efficiently index large BGP datasets. This included the development of both a scalable custom back-end database as well as an easy-to-use web front-end. The software is being used to operate an automated web-site that allows network operators to quickly query and extract externally visible routing information about their networks. Flarion Technologies Technical Staff, November 2003 - March 2004 - Responsible for implementing AAA using Oracle instead of a local database. - Implemented an automation framework using Expect/TCL for writing scripts to test various aspects of the RadioRouter - Wrote scripts to automate the task of gathering statistics and reconfiguring operational field-deployed RadioRouters - Software debugging Center for Satellite and Hybrid Communication Networks (University of Maryland) Research Engineer, August 2002 - November 2003 - Responsible for working with students (graduate and undergraduate), faculty, and industrial partners on various research projects in the areas of wireless networks, security, sensor networks, network modeling and simulation, and satellite networks - Led the design and development of a low-level sensor network emulation platform called ATEMU. This also involved working with and guiding student interns in the development of this project. The software developed under this project was released under the BSD license is in active use by sensor network researchers. - Responsible for developing an integrated wireless sensor network and Ad hoc network testbed to demonstrate a simple data gathering scheme using Berkeley Sensor Motes and embedded Linux CerfCube devices - Worked with another research engineer in the development of multicast routing protocol MAODV for wireless ad hoc networks; this led to a successful demonstration for industry collaborators and the software has since been made publicly available - Developed security scheme for 802.11-like wireless networks Laurel Networks Inc. Software Test Engineer, October 2000 - July 2002 - Responsible for testing L1-L3 related software and hardware - Responsible for testing oversubscribed Gigabit Ethernet PHY as well as core QoS features, including throughput - Responsible for testing Ethernet over SONET - Tested ARP, 802.1q, 802.1p, queuing/scheduling(WRR/WRED), packet classification, firewall filters, Layer-2-Transports, for both functionality and scalability as well as operation under stress conditions. Since all functionality is hardware based, this required in-depth understanding of the hardware architecture, as well as how the software was integrated with the hardware - Interoperability testing with Cisco(GSR 12000), Juniper(M10,20) - Extensive scripting experience via writing several automated tests, TCL/Expect were used for test automation - Experience in testing BGP, OSPF, SONET, MPLS, Frame Relay - Extensive experience with various test equipment including Adtech, Ixia, Smartbits, RouterTester(Agilent) Systems Engineering and Integration Lab/Center for Satellite and Hybrid Communication Networks(University of Maryland) Lab Manager/Research Assistant, April 1999 - October 2000 - MS Thesis "IPSEC and the Internet": Proposed and implemented the concept of Layered IPSEC in Linux by modifying the FreeS/WAN implementation of IPSEC for Linux - As Lab Manager: Developed cost estimates for proposal budgets, equipment acquisition for research, liaison with industry collaborators on research projects, developed and conducted research demonstration for various industry, army, and university personnel. Supervised graduate and undergraduate students on various research projects. Aggressively pursued a policy of recruiting undergraduate students for participation in research projects in the lab. Attended research review meetings, conferences and workshops - Implemented an experimental client-server based DBS video distribution with various compression techniques(MPEG1, CellB) over an ATM network using the Fore API and the SUN XIL interface - Designed and Implemented simulation scenarios/modules in OPNET for various networking projects, including TCP enhancements, TCP connection splitting/spoofing - Worked on implementing a Win95 Vxd (Virtual Device Driver) based software to forward DirecPC data from a satellite receiver interface onto a LAN for multicast applications. Developed an IGMP proxy system for forwarding multicast data Global Information Networks Inc., Rockville, MD Senior Internet Architect, March 2000 - October 2000 - Successfully took systems from design, concept stage through to live system demonstration. The project involved building a prototype network for providing Internet over Ka band satellite in Seoul, Korea. This was a very fast paced project where we went from initial concept to live system in a very short time span. This also required me to make 2 trips to Korea, to supervise the network installation. - Designed, implemented and tested a network for providing Internet over satellite - Integrated all network components, routers, caches, satellite modems, satellite gateways and all related software - Conducted multimedia demonstration of this Internet over Ka band satellite system for investors - Supervised a small group of engineers during this project, and worked closely with them - Developed innovative concepts for making the system scalable and commercially viable - Successfully conducted demonstration of the live system to VCs, which secured additional funding HRL Laboratories, Malibu, CA Summer Internship, Summer 1997, 1998 - Investigated issues related to Asymmetric Routing - Modified RIP(GateD) and DVMRP(mrouted) in Linux to work in an environment involving a Unidirectional Link. Verified their operation in various network configurations - Presented work at the 40th IETF - Setup RSVP test-bed in FreeBSD for QoS experiments - Investigated issues related to self organization in mobile ad-hoc networks Hughes Network Systems, Lakeforest, MD Summer Internship, Summer 1996 - Tested the DirecPC software for conformance to design specifications on various platforms (Win31 Win95 and WinNT3.51) - Designed setup and conducted tests to verify performance and functionality of the DirecPC Proxy Firewall server software (SOCKS4 compliant application) and the Newsfeed Transmitter and Receiver software (NNTP compliant application) - Setup test networks involving WinNT3.51 servers workstations and Win95 clients Publications: - D.
