Margaret Chiosi, vice president of Open Ecosystems in the US with Huawei, has been at the center of the telecom transformation since day one — as one of the authors of the original ESTI NFV ISG white paper, and as a strong proponent of open source at AT&T. Today, Chiosi is responsible for putting all that together at Huawei Technologies Co. Ltd. , where she is focused on making sure standards and open source are working well together.
