The Next-generation Network and Protocol System for Digital Networked Industry and Society
This article outlines the reasoning behind the New IP initiative, addressing the motivation (why) of the work, the definition and work areas of investigation (what) as well as the current progress (how). This is to clarify misunderstandings of what New IP entails as well as outline for our future partners on why and how to engage with us on this endeavor.
For this, the ITU-T Network 2030 Focus Group  established in July 2018, has been working on building consensus in the industry on the next evolution of Internet technologies, fit for purpose in 2030 and beyond. The societal and industrial digitalization will affect many vertical industries through enabling, for instance, industrial manufacturing through novel means for virtual and augmented reality or transforming education through full-view holographic multimedia. Communication means will include but not be limited to satellite networks, networked aircrafts and Internet of Vehicles, while also utilizing vast amounts of sensor network deployments with lightweight devices. The communication requirements of such digitalization is seen to accelerate the already changing focus from human-oriented communication to machine-oriented communication. Often large-data transmission is no longer the first target and the assumption that "large bandwidth is equal to high quality" is no longer universally applicable. Instead, determinism that provides network-layer certainty of information transmission becomes more important. One trillion  devices are being expected to be connected to the Internet in 2035 with heterogeneous, often resource-constrained, devices being connected via dynamic network topologies. As a result, networks need to cope with high dynamics and complex heterogeneous topologies while also supporting multi-channel concurrency (due to increasing access technology opportunities) and multi-channel collaboration (due to complex services with inter-twined dependencies for transmitted information). In all this, the need for security and privacy of information but also the infrastructure is ever increasing, together with the need to achieve sustainable efficiency of the utilized technologies.
Identifying the requirements has only been the first step, followed by outlining technology study areas for addressing them – we collectively call the set of these emerging study areas New IP and will outline them briefly in the following.
New IP can be characterized as a technology study initiative, driven by a vision on scenarios for utilizing Internet technologies in many facets of the future digital industry and society. As such research initiative, it is centered on study areas that address aspects of the Internet data plane as well as its associated architecture, technologies and protocols. These study areas address the identified requirements from associated efforts such as ITU-T Focus Group Network 2030 . New IP technology study initiative is not relevant to the governance model discussion. Instead, New IP addresses the study of technologies that fulfil the need for increased flexibility, determinism, and security & privacy, while also ensuring the continued need for ever-increasing throughput (over a plethora of multi-access technologies) as well as catering to very user-specific in-network data plane operations to achieve maximum Quality of Experience (QoE). More specifically, New IP covers the following aspects:
New IP is a suite of study areas for developing suitable evolved Internet technologies. New IP does NEITHER define governance models for the use of those technologies, NOR lead to “more centralised, top-down control of the internet” . In that, we follow established paths for developing Internet technologies in standard bodies, disconnected from the specific governance that operators and governments in the world decide upon. This is illustrated in our work on prevention of DDoS attacks, which indeed proposes the so-called “Shut-off protocol” . This concept is similar to proposals made by, for instance, Carnegie Mellon University scholars in the United States, as well as found in similar technologies that have been discussed in IETF DDoS Open Threat Signaling (DOTS) , among others. Such ‘shut-off’ is used by the attacked network to signal to the attacker’s source network the request for preventing further attack traffic . This technology is therefore well established in existing solutions.
Hundreds of high-level researchers from academia and industry in dozens of regions, including China, Europe, Japan, South Korea, North America, South America, and Africa, proposed future-oriented business visions and requirements with a focus on driving the wider societal digitalization through Internet technologies. We believe that the New IP initiative follows this tradition to the point through engaging with key international research communities to explore the space of possibilities to evolve IP technologies, while engaging with standardization organization to derive the requirements driving the evolution and ultimately agreeing on common solutions. In this, work in bodies such as the ITU Network 2030 focus group addresses the requirements, while our existing as well as future engagement with SDOs, such as IETF, ITU, ETSI, and others on a number of New IP solutions shows the integration into the consensus process the Internet community has established over time.
Contrary to the current politicized debate, New IP invites an open and free discourse through inviting researchers from all countries and industries around the world to participate in the research that would see IP evolve along the requirements found in relation to New IP and therefore drive the sustainable development of the global communication industry.
