Rethinking the Network Architecture and Protocols for the Tactile Internet 
Prof. Mohamed Faten Zhani (ÉTS Montreal, Canada) 

Abstract: From virtual reality and teleportation, to telepresence, augmented reality, holograms, and remotely controlled robotics, these future network applications promise an unprecedented development for society, economics and culture by revolutionizing the way we live, learn, work and play. In order to deploy such futuristic applications and to cater to their performance requirements, recent trends stressed the need for the "Tactile Internet", an Internet that, according to The International Telecommunication Union (ITU), combines ultra low latency with extremely high availability, reliability and security. Unfortunately, today's Internet falls short when it comes to providing such stringent requirements due to several fundamental limitations in the design of the current network architecture and communication protocols. This brings the need to rethink the network architecture and protocols, and efficiently harness recent technological advances in terms of virtualization and network softwarization to design the Tactile Internet of the future.

In this talk, we start by analyzing the characteristics and requirements of future networking applications. We then highlight the limitations of the traditional network architecture and protocols and their inability to cater to these requirements. We finally draw a rough sketch of a novel network architecture for the Tactile Internet and we discuss the potential mechanisms and control loops needed to ensure the service level guarantees required by future applications.

Abstract: New networking applications put ever-increasing demands on the Internet. For example, Industrial Internet applications involve controllers with ultrafast control loops subject to rigid timing requirements. Mission-critical Tactile Internet applications such as tele-surgery require ultra-low latencies without any loss in connectivity. Advances in network softwarization technology demand highly robust and fast control channels to allow to react to dynamic network conditions at line speed.

What all those application have in common is the need for "high precision" networking services that are able to guarantee the ambitious service levels and precise timing constraints demanded by those applications. These demands stretch existing "Best Effort" internetworking technology to its limits, and perhaps beyond, raising the question whether new networking architectures and protocols are needed. However, Internet technology has proven more adaptive to new requirements than thought possible on earlier occasions, as evidenced with applications such as VoIP or interactive video that were once thought not possible to support over the Internet. The question is whether that breaking point is finally about to arrive.

The panel will discuss whether the Internet is ready for High-Precision Networking. Can the need of new applications be addressed by mere advances in application and overlay technology, and if so, what are the technological gaps that need filling or is it just a matter of "more speeds and feeds"? Or are more fundamental changes at the networking layer needed, and what will be the characteristics and "first principles" of new solutions? What role do control technologies play, both centralized and decentralized? To what degree can edge computing provide the answer? What are the implications of high-precision networking for management, for measurements, for service assurance and fulfillment? And, what are the research questions that follow from those answers?

Alexander Clemm (Panel Moderator) is a Distinguished Engineer at Huawei’s Future Networks and Innovation Group in Santa Clara, California. He has been involved in networking software and management technology throughout his career, providing technical leadership for many products from conception to customer delivery, most recently in the areas of high-precision networks and future networking services as well as network analytics, intent, and telemetry. He has served on the Organizing and Technical Program Committees of many management and network softwarization conferences, including as General Co-Chair of CNSM (then: MANWEEK) 2007 and IM 2013 as well as TPC Co-Chair of IM 2005, Netsoft 2017, and IM 2019. He has around 50 publications, 50 issued patents, and several books (including “Network Management Fundamentals”) and RFCs. On the side, he has also been moonlighting on the Adjunct Faculty of Santa Clara University’s Computer Engineering department for a decade. Alex holds an MS degree in Computer Science from Stanford University and a Ph.D. from the University of Munich, Germany.
