The original design of Internet (or Internet 1.0) had no concept of ownership or policies and the routing was based on optimizing link costs. The commercialization of Internet in 1989 (which we call Internet 2.0) brought in the need for multi-organizational ownership of the infrastructure resulting in security issues and in Inter-domain routing, such as BGP. The ownership issues result in routing based on policy issues more than the cost or speed of links.
The ownership issues are limited not only to network infrastructure (network layer and below) but also to hosts, and users. Internet 3.0 architecture is proposed to allow to more accurately representing the ownership concepts of today's Internet in which there is a three tiered hierarchy of ownership. The users belong to organizations, such as companies or educational institutions, which may use clouds of hosts provided by utility computing companies, such as Amazon and may use infrastructure provided by service providers such as AT&T, Verizon, etc. The users may be interested in data objects, for example, movies that may belong of entertainment companies, such as Disney. Internet 3.0 allows the Internet to be any combination of host-centric, data-centric, user-centric, or infrastructure-centric. This also results in a need for multi-tiered virtualization of the Internet as compared to the single-tier virtualization of the infrastructure currently being discussed in research projects such as GENI.
