Topic:  Improving the Flexibility and Performance of Virtual Network Functions

Abstract:  Network Functions Virtualization (NFV) was recently proposed to improve the efficiency of network service provisioning, by leveraging virtualization technologies and commercial off-the-shelf hardware. It transforms how network operators architect their infrastructure by decoupling the software implementation of network functions from the underlying hardware. However, the current commercial implementations of Virtual Network Functions (VNF) are not cloud-friendly. There is still a gap between their performance and that of the physical network functions. This talk will start with a brief overview of NFV, introducing its design principles and research challenges. It will then present two recent projects at AT&T, EdgePlex and ParaBox, on improving the flexibility and performance of VNFs. EdgePlex decomposes and virtualizes the functions of a traditional edge router and enhances its flexibility. ParaBox is a novel hybrid packet processing architecture that reduces the latency of VNFs when they are provisioned in service chains.


Biography:  Bo Han is a Principal Inventive Scientist at AT&T Labs - Research. His current research interests are in the areas of network functions virtualization, software defined networking, mobile computing, and wireless networking, with a focus on developing simple but efficient and elegant solutions for real-world networking and systems problems. He obtained his Bachelor’s degree from Tsinghua University, his M.Phil. from City University of Hong Kong, and his Ph.D. from the University of Maryland, all in Computer Science. He has published 50+ papers in top-tier journals and conferences. He received the best paper award from ACM CoNEXT 2016.
