Biographical Sketch:
Mr. Ewy is actively researching collaborative approaches to probabilistic reasoning in network management and network security problems.

Mr. Ewy is a graduate teaching assistant and has been a lecturer for the Department of Electrical Engineering and Computer Science at the University of Kansas. He teaches the Internet Engineering program consisting of EECS 663 , EECS 745, and EECS 888, at the Edwards Campus in Overland Park, KS. and the Main Campus in Lawrence, KS.

Mr. Ewy founded PNE Services Inc. in 2000 to provide professional services in the areas of systems architecture and implementation. He has been involved in the development of software for processing the output of DNA sequencers, microscopy applications, and network management systems. He has managed large projects including data center relocations and complete WAN network deployments. He has provided architecture, implementation, and maintenance for high traffic e-commerce sites. His significant experience in the network security field has been utilized to perform detailed security audits and assessments, as well as after the fact incident analysis. He is responsible for the design, implementation, and maintainance of complete firewall systems for the healthcare, telecom, manufacturing, engineering, ISP, non-profit, education, research, and software industries.

Mr. Ewy co-founded and served as Vice President, and Director of Engineering for Ambient Computing, Inc. in 2000. He was the Principal Investigator of a $100,000 National Science Foundation Grant to coordinate wireless sensors and control devices. Mr. Ewy performed significant architecture and engineering work, including the hardware design of an embedded 802.11b based sensing and control platform, and the software development of key components of a wireless access control system.

Mr. Ewy was a co-founder and COO of a consumer network software startup, NetGames USA, which was acquired by Microsoft in 2000. At NetGames USA, Mr. Ewy co-developed the system architecture for a scalable, fault tolerant system that provided real time score tracking, statistics collection and presentation, and ranking for online game players. The service grew to support over one million online game players and generated 2.5 million page views per month. Microsoft has incorporated the NetGames USA technology into the Xbox Live system and games such as HALO 2. Mr. Ewy developed components of the authentication, tournament control, and denial of service protection for the system. He was also responsible for working with partnering companies to deploy software and services integrated into their commercial products.

Mr. Ewy managed a $6 million per year software development and testing laboratory and performed ISP service architecture and technology assessment for Sprint Corporation from 1997 to 1999. He represented the Sprint Long Distance network's requirements and capabilities to customers, vendors, and standards bodies including the Internet Engineering Task Force and the Digital Subscriber Line (DSL) Forum. His efforts there included collaboration on work that resulted in United States patent #6684251.

Mr. Ewy was entrusted with maintaining the security of Black & Veatch's world wide network serving over 6000 employees at 42 regional offices and 12 international sites in 1996 and 1997. Other network security work in 1996 included the co-development and testing of the first full rate OC-3 (155Mbps) proxy firewall for Trusted Information Systems using their Gauntlet Internet Firewall product as reported in Data Communications, September 1996, and the publishing of an article Creating A Linux Firewall Using the TIS Firewall Toolkit. in the Linux Journal, May 1996.

Mr. Ewy worked as a research engineer for the KU Center for Research, Inc. from 1992 to 1996, where he focused on two research projects. On the Rapidly Deployable Radio Network project, Mr. Ewy was responsible for the development of the system architecture for a wireless beamforming network prototype as described in IEEE JSAC April 1999. He designed and implemented a PCI based host network interface to the beamforming radio, including writing the Linux device driver. On the MAGIC Project, Mr. Ewy designed multiple hardware components of an OC-12 (622Mbps) ATM interface for a Digital AN2 ATM switch. This included performing the PCB layout, as well as component, board, and system level design, testing, and integration. FORE Systems, Inc. (now Marconi) released the first OC-12 interface for an ATM switch, but the KU gateway was operational only one month later, and had exclusive features desired by networking researchers including extensive traffic measurement capabilities, and both credit and rate based flow control as described in IEEE Network May 1996. His work on the MAGIC project exposed shortcomings in ATM WAN implementations, the result of ATM switch buffer design and these buffers interaction with the TCP flow control mechanism. The characterization of this problem, and the development of solutions resulted in a Masters Thesis, a version of which was presented at High Performance Distributed Computing 4 in 1995.

Benjamin J. Ewy is a senior member of the IEEE, a member of USENIX, a member of the ACM, and received the B.S.Co.E. and M.S.E.E. degrees from the University of Kansas in 1992 and 1995, respectively.
