RANGI: Evolving Internet Routing Architecture from Present to the Next Generation

We propose a clean slate design for the next generation Internet architecture that allows natural sharing of resources among multiple organizations. Our architecture consists of a 3-tier object model. The bottom tier consists of the network infrastructure owned by multiple Internet service providers. The second tier consists of hosts that may be owned by different organizations. The third tier consists of users and data objects. This results in a three tiered virtualization model as compared to the traditional single-tier infrastructure virtualization. In today’s Internet the infrastructure, the hosts, and users belong to different organizations (as in cloud computing) but are not correctly represented in the architecture resulting in several issues. We, therefore, propose an incremental architecture strategy that helps solve the problems of scalability, mobility, multihoming and traffic engineering in the current Internet, and allows evolving towards realizing the clean slate architectural goals.
