The Internet has evolved from being an academic pursuit to a huge commercial commodity. The IP thin waist, attributed to the simplicity of the present design has been a remarkable architectural choice motivated by the need to converge multi-ple link layer technologies and end-to-end trans-port mechanisms. However, the assumptions un-der which the original Internet was designed have changed. Newer contexts and speciﬁc requiremetns have subjected the original design paradigms of the Internet to a lot of abuse. Owing to the limita-tions of the underlying architecture, such overlaid hacks have limited eﬀectiveness and are often higly ineﬃcient.
