Amir S. Ranjbar

, CCIE No. 8669, is an internetworking trainer and consultant. Born in Tehran,

Iran, he moved to Canada in 1983. He received his bachelors degree in computer science (1989)

and master of science degree in knowledge-based systems (1991) from the University of Guelph

in Guelph, Ontario, Canada. After graduation, Amir worked as a programmer/analyst for Statistics

Canada until 1995 when he was hired by Digital Equipment Corporation as a certified Microsoft

trainer. After performing training on Microsoft Backoffice products such as Windows NT,

Exchange Server, and Systems Management Server for three years, he shifted his focus to Cisco

Systems. In 1998, he joined GEOTRAIN Corporation, which was later acquired by Global

Knowledge Network, and worked for them as a full-time Certified Cisco Systems Instructor until

2005. In October 2005, Amir started his own business (AMIRACAN Inc.) in the field of

internetwork consulting, but his major activity is still conducting training for Global Knowledge

Network on a contractual basis. His areas of specialty are MPLS, BGP, QoS, VoIP, and advanced

routing and switching.
