Revisiting the interior Border Gateway Protocol

The interior Border Gateway Protocol, commonly called iBGP, is a protocol that aims to exchange interdomain information within an autonomous system. Although it was developed more than 20 years ago, it remains currently the most used solution. However, the Internet has significantly grown over the years, requiring BGP to scale to the increasing number of routers. Although multiple solutions like route reflection and confederations have been deployed on top of iBGP, serious drawbacks persist. This work presents an alternative protocol, called the Core Routing Protocol, as an attempt to replace iBGP and to solve some of its issues. Along these chapters, CRP is defined in details and evaluated through different scenarios.
