Keynotes will be held every day in the main track of NetSoft. Their detailed schedule will be provided when we have collected all relevant information.
As for now, the following keynote talks have been duly confirmed.

What we need to overcome in order to benefit fully from Network Softwarization

Roberto Kung, Orange Labs, France

Keynote Description
Many technology evolutions are being introduced by network operators. Just to name a few, we can mention 5G with its devices (smartphones, IoT) and applications such as slicing, IT technology with Cloud and SDN/NFV, Open source (ORAN, ONAP, Open Stack…), AI and Machine Learning, Big data, blockchains… All these technologies contribute to advancing network softwarization. This will allow for benefiting for softwarization advantages: more flexibility/agility while being competitive.
However, contrarily to a piece of software or a piece of equipment, networks are difficult to upgrade as a whole as they have to live with different generations of equipment. For instance, it is difficult to decommission 2G network (or PSTN) as there are still many 2G phones (PSTN users). Another reason is the sheer cost of updating technologies. A network operator like Orange cannot spend much more than 7 billion euro per year. This may not be an issue if the ‘modern’ part of the network is available everywhere. However, the coexistence may be an issue from a cultural and process point of view. Usually Operators have decommissioning programs and cultural change programs. Another part which may be difficult to upgrade is the BSS/OSS. It may not be necessary to change everything, but it is necessary to allow for automated provisioning. Relevant plugs using TMF API are one possible solution. This will become key with the introduction of 5G Slicing and from the NSaaS (Network Slice) standpoint.
Obviously, there are also other issues related to the softwarization technologies:

  • How to handle the diversity of suppliers, leading to various ways of working and difficulties to integrate.
  • How to implement advanced agile mode while maintaining security with 3rd parties.
  • How to avoid vendor locking while the IT infrastructure stack is integrated with network applications
  • How to introduction an adequate underlying platform (‘Telco Cloud’), able to execute software where it makes most sense (centrally, or closer to the customer for better latency – milli-second).
  • Last but not least, how to go to a true noOps world with automation, allowing operation to focus on Quality Service improvement.

Roberto KungRoberto Kung is Senior Vice-President, Technology and Operations at Orange Labs, France. He is responsible for the Orange Expert program bringing together the top 600 orange experts on domains such as Network technologies and operations, Security, Data and AI, Software or Environment. The program also covers services aspects such as content, communication or transaction services.
He is responsible for Orange strategy on Network Operations, with a specific focus on smooth deployment of innovations (use of Orange Integration network, organization, processes, OSS/tools and operational support).
Prior to that, he has been Head of Orange Core Networks R&D, Head of Lannion site, Head of strategy in France Telecom’s Network division, Head of Strategy & Planning in France Telecom’s long-distance subsidiary. In the past, he has also been active in R&D, with the overall responsibility of all R&D activities within the Intelligent Network Program. He has been a member of TINA-C and responsible of the Working Group on Intelligent Networks at ITU-T.
Roberto Kung graduated from École Polytechnique in France and obtained a telecom engineering degree from Telecom ParisTech.

Software-Based Networks: Leveraging high-performance NFV platforms to meet future communication challenges

K. K. Ramakrishnan, University of California, Riverside, USA

Keynote Description
Communication networks are changing. They are becoming more and more “software-based.” The use of Network Function Virtualization (NFV) to run network services in software, along with the concept of Software Defined Networks (SDN), will lead to a largely software-based network environment. To truly achieve the vision of a high-performance software-based network that is flexible, lower-cost, and agile, a high-performance, carefully designed NFV platform along with a comprehensive SDN control plane is needed. Our open-source NFV platform, OpenNetVM, enables high bandwidth network functions to operate at near line speed, while taking advantage of the flexibility and customization of low-cost commodity servers. We envision a dynamic and flexible network that can support a smarter data plane than just simple switches that forward packets. I will describe the OpenNetVM architecture and scheduling frameworks that enable per-flow customization and rate-and-cost proportional fair scheduling of flows.

K. K. RamakrishnanK. K. Ramakrishnan is Professor of Computer Science and Engineering at the University of California, Riverside. Previously, he was a Distinguished Member of Technical Staff at AT&T Labs-Research. He joined AT&T Bell Labs in 1994 and was with AT&T Labs-Research since its inception in 1996. Prior to 1994, he was a Technical Director and Consulting Engineer in Networking at Digital Equipment Corporation. Between 2000 and 2002, he was at TeraOptic Networks, Inc., as Founder and Vice-President.
Dr. Ramakrishnan is an ACM Fellow, IEEE Fellow and an AT&T Fellow, recognized for his fundamental contributions on communication networks, congestion control, traffic management, VPN services, and a lasting impact on AT&T and the industry. His work on the “DECbit” congestion avoidance protocol received the ACM Sigcomm Test of Time Paper Award in 2006. He has published over 250 papers and has 172 patents issued in his name. K.K. has been on the editorial board of several journals and has served as the TPC Chair and General Chair for several networking conferences.  K. K. received his MTech from the Indian Institute of Science (1978), MS (1981) and Ph.D. (1983) in Computer Science from the University of Maryland, College Park, USA.
