Alan Sekelsky


Alan Sekelsky, CTO at LightGrid, is an internetworking engineering expert in advanced Internet Protocol (IP) network engineering, service development, network strategic planning, and network technology transition planning.

Alan Sekelsky has supported the Defense Information Systems Agency (DISA) since 2002 and currently provides support to the DISA Infrastructure Executive as technical advisor for the evolution of Defense Information System Network (DISN) services and infrastructure. He is the lead author of the DISN Overarching Technical Strategy (DOTS) and lead technical author of the DISN Technical Evolution Plan (DTEP).

Mr. Sekelsky served as the Technical Director for support to the DoD IP version 6 (IPv6) Transition Office (DITO) and the DISA IPv6 Transition Office. Through DITO, he provided DoD-wide IPv6 project management under the direction of the Assistant Secretary of Defense for Networks and Information Integration/DoD Chief Information Officer [ASD(NII)/DoD CIO]. Under Mr. Sekelsky’s direction, DITO successfully coordinated with the American Registry for Internet Numbers (ARIN) to obtain the largest contiguous IPv6 address allocation for DoD networks.  Technical oversight and guidance included IPv6 implementation planning, network engineering, network management, information assurance, testing, and standards analysis.

Alan Sekelsky served as the IP Team Lead for the DISA Global Information Grid – Bandwidth Expansion (GIG-BE) program support, which was selected as the DISA Outstanding Program of the Year. He successfully lead a multi-function engineering team in a multi-year technical specification and evaluation effort covering IP router capabilities including Multi-Protocol Label Switching (MPLS), quality of service (QoS), multicast, virtual private networking (VPN), platform performance and design, network management, and information assurance. Mr. Sekelsky also provided engineering leadership to DISA in network architecture and design, protocol selection and configuration, routing infrastructure integrity, service definition, and lab verification leading to the GIG-BE network initial operational capability (IOC).

Prior to joining LightGrid, Mr. Sekelsky held senior technical management positions at UUNet (now Verizon) and Teleglobe, two of the largest global commercial Internet Service Providers (ISP). At UUNet, Mr. Sekelsky managed the Systems Verification Team whose mission was to emulate the operation of the UUNet global network and test technology insertion and architectural modifications in a controlled laboratory environment. He was Senior Manager for Technology Planning at Teleglobe where he researched emerging technologies, developed MPLS and IP evolution strategies, and supported service development. For over ten years, Mr. Sekelsky was an Aerospace Engineer at the Naval Surface Warfare Center (NSWC) Carderock Division, where he served as the technical and operations facility manager, lead test engineer, and electronic instrumentation and computer systems manager for the NSWC Subsonic Wind Tunnel.

Mr. Sekelsky holds an M.S. in Electrical Engineering from George Mason University (GMU) and a B.S. in Aeronautical Engineering from Rensselaer Polytechnic Institute (RPI).

In the community, Mr. Sekelsky has volunteered his time coaching youth athletics and supporting Relay for Life teams, community management, and scouting activities.
