(Formerly Unisphere & Argon Networks)                                                4+ years

Principal Senior Software Engineer

Vital technical resource supporting the company’s only product, Gigapacket Switch, throughout acquisitions from Argon Networks to Unisphere to Juniper Networks.

Argon Network’s mission was to create an integrated routing & switching platform for core and high-speed access layers of Public Networks. The Gigapacket Switch was engineered for 99.999% service uptime, and tightly integrated with existing access and transport networks.

Unisphere Networks was created from 3 startup companies purchased by Siemens Corporation (Argon Networks, Castle Networks, Redstone Communications). The network core router developed by Argon Networks was integrated with Redstone Communication’s ERX product line and become the MRX (released and shipped in the second quarter of 2001).

Key Accomplishments:

·         Within 6 months of hire, completed the proposal, design and review phases of the Frame Relay stack (part of the Gigapacket Switch product feature set) that had been in development for over one year.

·         Expedited development, averted future issues and produced beneficial changes by attending design reviews and contributing to the evaluations of other subsystems to ensure compatibility with the Frame Relay design.

·         Reviewed and evaluated the design for the interface between the Frame Relay hardware driver and ASIC Interface, providing all Link Management (LMI) traffic.

-         Identified a flaw in the initial design of the ASIC logic that would have caused LMI traffic to be discarded.  Partnered with an ASIC Hardware Engineer to correct and verify the logic, avoiding post-tape out errors in hardware design.

·         Major contributor in the full integration (pre-ALPHA) testing of the MRX product, focusing on the creation & destruction of circuits involving IP, PPP and/or Gigabit Ethernet protocol stacks.

-         Uncovered minor configuration and operational problems that were fixed and retested within hours of their discovery.

·         Effectively completed PPP and Gigabit Ethernet alpha & beta testing as well as subsystem integration/testing with remaining MRX subsystems.

-         Bugs reported were an aggregate count of less than 10, with an average turnaround time of less than 1 day per bug.

·         Produced a comprehensive User's Guide for both the Point-to-Point and Gigabit Ethernet Stacks, providing information and insight on the relevant external interfaces, configuration, protocol stack options, managed SNMP objects and troubleshooting problems.

·         Implemented and integrated the MRX Point-to-Point Protocol (PPP) Stack 2 weeks ahead of schedule, with zero changes required.

·         Designed and implemented a 'non IPV4' packet handler that interfaced with the MRX ASIC Driver, handled all non-IPV4 packets received by the ASIC, determined the protocol the packet contained (BGP, PPP, OSPF, IS-IS, IS-ES, CLNP, RIP, MPLS, IGMP & others), and forwarded packets to the appropriate software subsystem.

·         Two months after initial design and implementation, deployed the MRX Gigabit Ethernet stack (IEEE 802.3) with VPN support on time with zero lost transition time.

·         Transferred to the ERX Software Development Group until company layoff, resolving challenging problems reported against the PPP subsystem in the ERX Router (predecessor to the larger MRX Router).

-         Performed extensive research to solve highly customer-dependent bugs, increasing the reliability of the product.

Environment:      Gigapacket Switch, Frame Relay, ASIC, MRX, IP, PPP, Ethernet, VPN, ERX

Principal Consulting Engineer                                                                 6 years

Major contributor in the initial design and implementation of a portable Frame Relay Protocol Stack, the first product offered by this privately held and rapidly growing company started by former Motorola/Codex employees.

Key Accomplishments:

·         Implemented and tested new features within the Frame Relay product as standards were ratified (RFC1490, FRF.16, FRF.1.1, FRF.3.1, FRF.12), enabling company to continually maintain its competitive edge.

·         Designed and prototyped the Layered Environment for Accelerated Portability (LEAP) architecture, reducing communications software integration up to 50%.  Decreased time for porting products to customer equipment from 3 months to 2 weeks.

·         Established standards and procedures for internal software development and Frame Really stack acceptance testing.

·         Successfully completed on-site contracts with CoastCom (2 years) and ACT Networks (1 year) for the inclusion of Frame Relay in T1 product lines and the design/implementation of SDLC with LLC Spoofing over Frame Relay.

·         Conducted seminars on Frame Relay and ATM product lines in US & Europe. 

Environment:      Frame Relay Protocol Stack, T1, ATM

Principal Engineer (1989 - 1992)

Senior Software Engineer (1986 - 1989)

Key Accomplishments:

·         Led design team in the initial development of a Windows-based 9300 NMS Network Management System.

·         Built a LEX/YACC-based parser for interpreting Multiplexer Console output, enabling Multiplexers to be placed under Network Management control.

·         Developed and implemented the software build process for nightly builds.

·         Produced white papers and proposals for future directions of the Network Management product.

·         Drafted feasibility studies and conducted due diligence investigations from marketing proposals.
