Routing policies in named data networking
Steven DiBenedetto, Christos C. Papadopoulos, Daniel F. Massey · 2011
Modern inter-domain routing with BGP is based on policies rather than finding shortest paths. Network operators devise and implement policies affecting route selection and export independently of others. These policies are realized by tuning a variety of parameters, or knobs, present in BGP. Similarly, NDN, a information-centric future Internet architecture, will utilize a policy-based routing protocol such as BGP. However, NDN allows a finer granularity of policies (content names rather than hosts) and more traffic engineering opportunities.
