Towards an incremental deployment of NDN: robust bootstrapping using in-network indirection

Abstract

Incremental deployment of new Internet architecture is a key challenge for the smooth evolution of the current Internet. In NDN, the overlay-based deployment is considered as one of the promising options to provide NDN services over the Internet. To achieve an incremental deployment, it is required to design a bootstrapping mechanism that allows consumers to consistently access to an overlay NDN network in a situation where Autonomous Systems (AS) are gradually deploying NDN routers. In this paper, we analyzed the current bootstrapping and identified its potential issue in specifying the IP address of the closest NDN router. We propose a robust bootstrapping architecture that can work without specifying the exact IP address of a single NDN router. By using in-network indirection, our scheme can provide consistent access to the NDN network independent of the deployment status of each AS.
