This RFC proposes a model for describing routing within the Internet. This memo does not specify an Internet standard.
Comments are welcome.
Distribution of this memo is unlimited. The authors would like to thank Guy Almes of Rice University for his contributions and insight. Furthermore, the Autonomous System concept has been outgrown in certain parts of the Internet, in which the complexity of regional routing has exceeded the limits of the definition of Autonomous Systems. This framework proposes a structure of Routing Domains within Administrative Domains. This paper is intended to briefly describe this framework, to outline how this model better fits the reality of the present and future Internet, and to show how the model can aid in the construction of well-engineered routing environments.
