Introduction, welcome from the chairs


Session 1:  Cedric Westphal (Futurewei) – Chair


Invited Talk: Can we use CubeSats as the Backbone Network for Next Generation Communications Systems?

As the Internet evolves to support over 30 billion connected devices by 2021, the reach and connectivity offered by the traditional wired backbone is fast becoming a bottleneck. Nanosatellites, or CubeSats, are envisioned as a promising solution for future backbone communication networks because of their low costs and short deployment cycle. A new generation of CubeSats equipped with multi-band radios for communication in radio frequencies, millimeter wave and terahertz bands has made terabit per second (Tbps) links possible. A dense network of CubeSats worldwide offering Tbps-level connectivity provides an excellent opportunity for realizing the backbone network for next generation communications. Furthermore, this next-generation CubeSat backbone has much to benefit from Software-Defined Networking and Network Function Virtualization which provide fine-grained control over the system hardware, improve network resource utilization, and simplify network management. In this talk, a complete system architecture for global CubeSat networks coupled with a ground-based control and management framework is presented, along with novel solutions for large-scale network topology design and low-overhead routing.

Invited Talk: Innovating at the Network Layer -- How to (Not) Make the Internet Better

The past 15 years have seen several attempts of redesigning the Internet to address issues in different areas. Yet, it has been incredibly difficult to transfer the corresponding results into the running system. Even the introduction of IPv6, a minor upgrade from a research perspective, is happening at an incredibly slow pace. Based on experience in Future Internet Research, Internet Engineering and Applied Industry Research, this talk will distinguish pressing problems in the current Internet from less important ones and discuss areas that absolutely need innovation, as well as viable directions and strategies to actually make the Internet better.

Invited Talk: Network protocols are dead, long live networking abstractions!

The ossification of the networking layer has long limited the evolution of networking services and applications. The emergence of programmable data planes and their inherent flexibility has enabled the broader community to revisit the network's role.  However, this flexibility is limited, and we lack sufficient primitives to harness and manage this flexibility effectively. This talk will discuss challenges that arise when the network is extended to support rich distributed systems abstractions, i.e., in-network computing, and sketch out a broad set of primitives for enabling in-network computing effectively. I will also describe ongoing work to extend our abstractions to manage traditional accelerators, e.g., GPUs and FPGAs.

Session 2: Enrico Natalizio (LORIA) – Chair


Invited Talk: Evolving IP to support Emerging Applications?

The Internet protocol suite has withstood numerous challenges that emerging applications have continually posed over the last several decades, and has admirably served the needs of our information driven society. The fundamental principles behind the design continue to serve us well even in these challenging times. Given this background, is there a reason to reconsider enhancements to the network layer in the context of even newer applications that are likely to emerge as we grow more and more dependent on networking. This will discuss a few applications that are gaining traction that can be substantially helped by a network layer more responsive to application needs in terms of latency, flexible naming and service features. Vehicular applications, rich 360-degree video distribution and augmented reality are emblematic of such emerging applications, and I will discuss the network layer features that these applications could use to improve their capabilities.

Invited Talk: Future IP: which network programmability challenges?

Network programmability has arguably been the mainstream research topic in networking for the last dozen of years, and any future Internet proposal cannot prescind from this. Actually, some among the more visionary proposals even bring back into play some original active networking ideas, such as software code embedded in the packets themselves. But which programming abstractions may sustain such a deep level of programmability? And does this trend call for innovative data-plane programming architectures capable to process packets at multi-gigabit wire-speed? These, as well as additional issues and challenges, will be discussed during the talk, with in mind the application to proposals for future Internet Protocols.

1st International Workshop on the Future Evolution of Internet Protocols
IPFuture 2020
Izmir, Turkey, 02 November 2020
Co-located with CNSM 2020

IP - as the backbone of the Internet- has enabled an amazing deployment of platforms and applications. However, the design of IP in the 1970s did not consider many of the requirements of the applications of the 2020s and beyond. No matter how prescient the design of IP was, nothing lasts forever. The search for a future network protocol has produced so far, a new version of IP, IPv6 that is now used by a third of the Internet users. IPv6 is considered incremental, as it does not challenge the key design principles of IPv4.

Researchers have started to look for successors of IP. NSF funded some Future Internet Architecture projects as well as some Clean Slate programs. Similarly, the EU Framework Program 7 and Horizon 2020 hoped to promulgate new network architectures and protocols for the Internet. Non-IP network architectures, such as NDN, have been proposed and enjoy some popularity within industrial and academic research.

Yet, before any replacement of IP is deployed, it will require deployment in operating systems, forwarding and routing elements, end-user clients, etc. This challenge to the status-quo would require the buy-in and motivation of many people: researchers, product developers, business strategists, CEOs. One key question to answer is: “what is the compelling need for a new architecture?”, and “What will really happen to the Internet (and the businesses that run over it) if we keep IP as it currently is?”

Identifying simple, intuitive examples that demonstrate the failure of the current design and the need for change, is a requirement before designing a successor to IP. Many new applications may stretch IP beyond its limits. It may be autonomous driving or the IoT; or industrial Internet and machine-to-machine communications; or new applications such as holographic communications or haptic support, etc.

To enact change will be much easier if there is a set of mutually agreed examples describing modes where IP falls short. Absent compelling examples, it is unlikely that any new protocol architecture would catch the fancy of any industry leaders, once they factor in the cost and risk of change.

The goal of the workshop is to identify compelling scenarios were IP is clearly insufficient. We hope that these scenarios could become the examples required to foster change in the industry.

The focus of the workshop is on the problems facing IP in the future, and any presentation in the workshop should focus on a problem/shortcoming before proposing any solution.

Revised and extended versions of Best Papers published in the workshop will be invited for fast-tracked publication in Computer Networks.

Topics of interest include but are not limited to:

  • Shortcomings of the IP architecture
  • Applications that will require new network services currently not supported by IP
  • Network protocols optimizations for Industrial and Tactile networks
  • Network security and privacy issues that cannot be fixed with the current network layer
  • Innovations in routing technologies and addressing in networks
  • Motivations for Future Internet Architecture, including Information-Centric Networks
  • Network requirements and challenges for VR/AR and Holographic type communications
  • Network requirements and challenges for Tactile networks
  • Network requirements and challenges for Industrial Internet and massive M2M communications
  • Business models and incentives for Beyond IP network architectures
  • Challenges in managing IP networks that can be alleviated with better network support
