5G systems are set out to address the business contexts of 2020 and beyond, by enabling new network and service capabilities, opening up innovation opportunities for vertical markets. Communication service providers should be able to provide tailor-cut solutions to service requests from the verticals over the same network infrastructure. Network slicing provides a solution towards this end; it is considered a key for meeting 5G’s diverse requirements, including future-proof scalability and flexibility. However, to support the multiplicity of applications and services, we need to automate and optimally orchestrate networks through dynamic network slicing. Automation should be enabled throughout all phases of the network slice lifecycle through optimized closed-loop control at different levels and time-scales. In this talk, we will discuss the envisioned service automation architecture and focus on aspects related to orchestration and data plane programmability. The aforementioned topics constitute the research agenda of the Nokia Bell Labs Access Network Control department in Antwerp, Belgium.
Chrysa Papagianni is a network research engineer for the Access Network Control department of the End-to-end Network Service Automation lab, since 2018. She received her Diploma and Ph.D. in Electrical and Computer Engineering, both from the National Technical University of Athens (NTUA), Greece, in 2003 and 2009 respectively. From 2010 to 2016, she was a Research and Teaching Associate for the School of Electrical and Computer Engineering of the National Technical University of Athens. Prior to joining Nokia Bell Labs, she was a Research Scientist for the Institute for Systems Research, at the University of Maryland in the United States. Her research interests lie primarily in the area of computer networks and distributed systems with emphasis on virtualization, network optimization, management and service provisioning, cloud computing and software defined networks.
