Bell Labs Career

  • 2011: MTS, Computing and Software Principles Research Department. I have invented Periodic Early Detection (PED), an active queue management scheme for buffering TCP traffic that helps maximize the utilization of network links and the energy efficiency of the rate-adaptive interfaces that will eventually drive them.
  • 2008-2011: MTS, Computer Systems Research Department. I was one of the founders and active members of the Cooler Networks team, which reached the final-six phase in the 2008 Bell Labs Grand Challenge Challenge with a proposal for developing ground-breaking energy-saving network technologies. I developed insights in the fundamental properties of Packet-Timescale Rate Adaptation (PTRA) techniques that identify key priorities and constraints for the deployment of PTRA in practical network systems.
  • 2006-2008: MTS, Security Solutions Department. I contributed in many ways to the development and commercialization of the OmniAccess 3500 Nonstop Laptop Guardian platform: architectural design, system engineering, documentation management, sales team support.
  • 2003-2006: MTS, Embedded Software Department. I designed and developed the implementation of the Remote Network Monitoring (RMON) functionality in the LightStack GSLAM product. I specified and implemented the QoS architecture of the Stinger 2100 Control Module (DSLAM application). I represented Lucent Technologies in two WiMAX Forum working groups, assuming the Lucent lead role in one (Service Provider Working Group) and supporting the Lucent lead in the other (Network Working Group); I was also a prominent contributor to the IEEE 802.21 Working Group (Media-Independent Handover).
  • 2000-2003: MTS, Data Networking and Wireless Systems Research Department. I contributed to the revolutionary architecture of a 3G-wireless Radio Network Controller based on network processors (as opposed to solutions based on general-purpose processors) and specified end-to-end QoS frameworks for the following multi-service systems: GEMS (MPLS-based Layer-2 VPN system), TMX-880 (ATM/MPLS core switch), and LightStack GSLAM (Metro Ethernet system for video distribution).
  • 1996-2000: Visiting Researcher/Member of Technical Staff (MTS), High-Speed Networks Research Department. I contributed fundamental research advances in the fields of packet scheduling, buffer management, traffic shaping, and flow control to the design and implementation of the ATLANTA ATM Port Controller, a market-leading traffic-management chip for ATM switches (also adopted in the Alcatel-Lucent CBX500 and GX550 multi-service WAN switches). I led the specification of the traffic management architecture for the ATLANTA Pi-X/Pi-C chipset, a QoS-aware switch fabric for ATM and IP switches/routers; the architectural breakthroughs I applied to the chipset constitute to date one of the dominant trends in the art of packet switching.
