Interested in history?
Ivan Pepelnjak, CCIE No. 1354 Emeritus, has built his first proprietary WAN network in early 1980's. He has been designing, installing, troubleshooting, and operating large service provider and enterprise WAN and LAN networks since 1990, and server as chief technology advisor at NIL Data Communications for well over a decade.
In his role as technical director of NIL Data Communications, Ivan focused exclusively on large-scale IP networks, became one of the early Cisco Certified Internetworking Experts (CCIE) and one of the first Cisco-certified instructors. His extensive knowledge helped service providers, such as British Telecom, Deutsche Telekom, France Telecom, Global One, Telia and SITA deploy large-scale state-of-the art IP or MPLS networks. Large corporations benefiting from his experience include equipment manufacturers and integrators, such as Cisco Systems, Digital, Hewlett Packard, IBM, Unisys, as well as banks (Dresdner Bank in Germany) and petroleum industry companies (Statoil in Norway). He was also able to transform the hands-on experience gained in consulting projects into an educational framework when he was one of the architects of Cisco Systems' Service Provider curriculum and the lead developer of several Service Provider-focused courses covering Border Gateway Protocol (BGP), Multi-protocol Label Switching (MPLS) and IP Quality of Service.
These days, you'll likely find Ivan solving interesting networking, SDN- or web-related challenges or you might find him hiking, mountain-biking or rock-climbing somewhere high in the European Alps.
