FlexNGIA: A Flexible Internet Architecture for the Next-Generation Tactile Internet

Abstract

From virtual reality and telepresence, to augmented reality, holoportation, 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 [1]. Unfortunately, todays 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 paper, 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. Afterward, we put forward a novel network architecture adapted to the Tactile Internet called FlexNGIA, a Flexible Next-Generation Internet Architecture 1 . We then describe some use-cases where we discuss the potential mechanisms and control loops that could be offered by FlexNGIA in order to ensure the required performance and reliability guarantees for future applications. Finally, we identify the key research challenges to further develop FlexNGIA towards a full-fledged architecture for the future Tactile Internet.

A Survey on Green 6G Network: Architecture and Technologies

“…differential priorities for data and high-precision synchronization for multipath transmission) to accommodate future communication needs. In [45], a cross-layer transport layer was advocated. It merges traditional network and transport layer and carries out functions of both layers at the same time.…”

6G Ecosystem: Current Status and Future Perspective

“…As an example, while transmitting an advertisement of a particular type of food, its smell, texture, and taste shall be transmitted together with the help of advanced sensor technology and Apps to give a real feeling of the food. The 6G network will serve the need of these verticals due to its ultra-high data rate and low latency [18,75,88].…”

Evaluation of Internet Generations on Wireless Network: A Survey

“…Authors pay more focus on evaluation the geographical region of IPV4 core. Zhani et al (2020) this paper discuss about the internet architecture using the Next Generation Internet and discuss the layers of OSI model and discuss the limitation of internet like compatibility issue and emphasis on the network services provided by internet. Arshad et al (2019) is review on the cellular technology change according to the various generations and discuss about the features like QoS, online gaming etc and compare the various generations based on frequency, bandwidth and performance.…”
