Sachidananda Kangovi, also known as Sach Kangovi, is an American technology executive, aerospace engineer, and an author, known for developing 'Service Linked Multi-State' system (SLIMS), a critical part of the Telecom provisioning and activation system. He has also involved in the development of a facility to test exhaust flow from rocket and jet engines, designated by National Aerospace Laboratory as one of the world's most exceptional and one-of-a -kind testing facilities. He is the author of three books of which Peering Carrier Ethernet Networks, published by Elsevier, has been adjudged by 'BookAuthority' as one of the best Ethernet books of all time.

Biography
Sachidananda Kangovi, born in the Indian city of Bengaluru on August 25, 1948, earned a bachelor's degree in engineering from Jabalpur Engineering College and a master's degree from Indian Institute of Science. His doctoral studies were at Rutgers- The State University of New Jersey from where he got his Ph.D. in 1977, under the guidance of D. Robert H. Page. He started his career as a senior scientist at National Aerospace Laboratory in 1971 before moving to the US in 1982, to work on computational fluid dynamics (CFD) at Boeing, and Johnson & Johnson. Later, he worked on information technology at Comcast, AT&T and erstwhile Satyam Computer Services, an India-based global IT Company as the vice president of Telecom sector.

Achievements
Kangovi designed and developed a test facility called 'Base Flow Facility' to study the effect of exhaust flows from rocket engines and jet engines on thrust as well as control surface effectiveness and this facility has been designated as one of the world's most exceptional and one-of-a -kind testing facilities by the National Aerospace Laboratory. At Comcast as Design Lead and Distinguished Engineer, Kangovi spearheaded a team of designers to develop the Service Linked Multi-State (SLIMS) System,, a critical part of Telecommunication provisioning and customer activation system. His work on Service Linked Multi-State (SLIMS) earned him several US and global patents. As a Senior Enterprise Architect at AT&T, Kangovi worked on the end-to-end solution architecture of OSS/BSS system for the MEF standard-based External Network-to-Network Interface (ENNI) project, an AT&T initiative called Velocity IP (VIP) and Fiber Broadband Services (FBS). While at AT&T, he authored a reference book titled Peering Carrier Ethernet Networks published by Elsevier in 2017. This book was adjudged by 'BookAuthority' as one of the best Ethernet books of all time while The Law of Disorder is being cited by many researchers in their theses/papers.
