1.1 Introduction

Due to the extraordinary spread of the omnipresent internet as well as IoT device dispersion, the Internet is growing at an exponential rate. From the perspective of the devices, rather than at the Internet's core infrastructure, this development is mostly taking place on its outskirts. Next-Generation Internet is an umbrella term that encompasses a range of technological advancements and innovations. NGI incorporates the use of artificial intelligence and machine learning technologies to enable more intelligent, personalized, and efficient internet services. One of the key technical components of NGI is the development of advanced networking technologies, such as software-defined networking (SDN) [1] and network function virtualization (NFV) [1]. These technologies are designed to improve network flexibility, efficiency, and scalability, making it easier to manage and optimize complex network infrastructures. Although the current Internet has been phenomenally successful, its foundational network is weakened by the limitations of the IPv4 protocol, such as address space exhaustion, lack of quality of service, and security vulnerabilities. To address these issues, a transition to the Next-Generation Internet is necessary, with the Internet Engineering Task Force (IETF) [2] proposing IPv6 as a solution since 1991. IPv6 became standard in 1995, and the IETF established a free test bed called 6Bone [3] in 1996 to evaluate IPv6 before phasing it out by 2005. IPv6 provides numerous technical benefits, such as a larger address space, enhanced efficiency, improved security, and better quality of service [4].

The conventional network framework also entails significant cost implications. The expense associated with procuring network equipment, including routers, switches, and other networking devices, is often exorbitant. This prohibitive cost poses a challenge for organizations to justify the expense of upgrading or replacing their existing infrastructure. Moreover, managing a large network's complexity can be expensive in terms of personnel and training costs. Furthermore, traditional networks typically necessitate dedicated hardware and software for specific tasks like load balancing or security, which can further escalate costs. In contrast, emerging software-defined networking (SDN) and network function virtualization (NFV) technologies provide more flexible and cost-effective alternatives to traditional network architectures. In a traditional network, the control and data planes are both embedded within a single device. One of the major problems that traditional architecture faces is that it is a closed network architecture [5]. Manufacturers of network equipment have their own hardware, operating system, application of standards, and extended range of functions. This implies that timely testing and verification of the new techniques are not possible. This is because the system is only accessible to the manufacturer. In a conventional network, switches serve as both the controller software and the forwarding element. Software instruction simply imposes rules that dictate the forwarding component. These networks are intricate and challenging to control [6]. When the data plane (forwarding devices) and the control plane (one that regulates network traffic) are combined into a single network device, it becomes more sophisticated. This architecture decreases flexibility and eliminates the opportunity for innovation, preventing the advancement of network infrastructure.

A distributed system is a collection of independent computing pieces that seem to users as a single cohesive system. Distributed systems are characterized by geographically dispersed computers, which are interconnected using wired, wireless, or hybrid networks [7]. The size of a distributed system can range from a few devices to a vast network of millions of computers. These systems are highly dynamic, with computers frequently joining and leaving, causing continuous changes to the network topology and performance [8]. Building and maintaining distributed systems can be challenging, as there are several limitations and trade-offs to consider. Users may be located in various parts of the world, and that can introduce issues with network latency and communication. It is difficult to completely prevent failures of networks and nodes, and distinguishing between slow and failing computers can be tricky. It is also hard to be certain that a server performed an operation before a crash and achieving full transparency in a system can come at the cost of performance. Keeping web caches up to date with the head can be difficult, as can immediately flushing write operations to disk for fault tolerance. Despite these challenges, it is important to consider all the factors while designing and building distributed systems to ensure that they are dependable and efficient. The current internet is made up of a patchwork of different technologies, standards, and protocols, which can make it difficult to integrate new applications and services. To achieve the next generation of the internet, there will be a need for greater interoperability between different systems and devices, as well as more open and standardized protocols for data exchange and communication. Achieving the next generation of the internet will require a collaborative effort between organizations and individuals around the world, as well as significant investment in research, development, and infrastructure. To effectively construct the next iteration of the Internet, a comprehensive outlook is required, encompassing a range of topics such as advancements in the physical and transmission layers of both conventional and wireless media, in addition to the implementation of new switching and routing paradigms at the device and sub-system layer. Additionally, it is necessary to consider alternative approaches to TCP and UDP for data transport in emerging environments, as well as novel models and theoretical frameworks for comprehending network complexity [9].
