PROFESSIONAL EXPERIENCE:

Confidential, Aberdeen, MD

Senior Radio Network Engineer (Modeling and Simulation)

Responsibilities:

• Utilized and modified packet correlation toolset to generate network loading, congestion, PPPOE stats.
• Utilized radio performance statistics and throughput to determine overall antenna test performance.
• Compared performance to system specifications, assisting transmission team on site.
• Extracted OSPF metrics from packet captures and correlated to traffic flow.
• Integrated SITL (system-in-the-loop) library from OPNET with real PPPOE frames from routers and radio surrogate VMs, wrote, tested and utilized custom translation function (basically decoders) for SITL for PPPOE/PPP protocols.
• Developed error model for Ruggedized MPM modem for NCW using OPNET’s BER table and EMA functionality. Used Matlab to do broad fits to the BER data. Modified NCW model code to take into account errors during packet transmission.
• Investigated Software Defined Networking technologies including OpenFlow Confidential a proposal stage to see whether the tactical network would benefit from an SDN implementation. Developed and submitted proposal to go forward with SDN study on MANET and satcom networks.
• Utilized and developed OPNET simulations to represent WIN-T networks, creating GRE tunnel networks running multicast protocols.
• Ran simulations to determine multicast performance. Took week long OPNET Modeler, IT/SP Guru, AppExpert* classes. Interacted with Systems Engineering and general simulation community to build ideas for upcoming simulations for Inc2/3, gateway routing, etc.
• V&V tested NetOps reporting tool used for trending the data collected via packet capture for WIN-T program. Interacted with code developers to enhance presentation, take ownership of problems found, and expedite the process of productizing tool for field tests. Worked with JHUAPL and PM WIN-T to rectify issues (timing, packet optimizations) arising from handle real live data captured from field test. Helped to develop and test windowing code to allow limited memory footprint while analyzing terabytes of data captures. Glenn D. BlanfordResume Page 2
