ABSTRACT
The immense proliferation of present day Internet has changed not only the initial context of networking but also the way it is used nowadays for enormous content dissemination. During its evolution, Internet has linked billions of users across the globe and revolutionized through almost all spheres of human life including commerce, newspapers, television, and transportation, besides bringing information and education. Also, it has grown into the network of innumerable inter-linked devices, user specific services, and Internet applications. However, the present TCP/IP protocol stack-based Internet design, which brought the utilization of Internet all over the places, is not well adapted to today’s Internet usages and services rendered and consequently reaching its age. New communication technologies, architectures, protocols, and mechanisms are being explored for new Internet principles and designs that would be highly appropriate for running the Internet-based applications and rendering the user-specific services in the future. There is a need to implement new architectures loaded with brand new set of protocols and mechanisms to handle the content distribution and services efficiently. Hence, all sort of the research to connect new devices, rendering improved services, and deployment of modern applications are paving ways for future Internet technologies. Among various serious attempts which were caused to propose differencing potential Internet paradigms for the future Internet, “to emphasize on delivery of the content independently rather than being dependent on host’s location holding the content,” is one of the most common efforts. This chapter in essence narrates the conspectus of various such differing future Internet designs which are based on the idea of content dissemination independent of the location of the content. The main intention of this chapter is to transpire the readers with the fundamental architectures, protocols, and mechanisms for the next-generation Internet.
