Margaret Chiosi, AT&T's well-known and outspoken Distinguished Network Architect who has been one of the lead individuals in the virtualization community, has retired from the Tier 1 US operator, Light Reading believes.
Chiosi was due to speak at the Big Communications Event (BCE) this week in Austin, Texas, but retired suddenly last week: Toby Ford, AVP of cloud technology, strategy and planning at AT&T Inc. (NYSE: T), stood in to provide the BCE crowds with an update on the operator's virtualization efforts.
In a statement issued to Light Reading, AT&T noted: "Margaret retired on May 16 after 39 years of service at AT&T. She didn't indicate her future plans but we wish her the best of luck."
Chiosi has long been a prominent figure in the telecom sector, driving AT&T developments in the Ethernet and optical sectors and playing a significant role in the formation of the virtualization community in telecoms. For more on her background and involvement in the industry, see:
