Measuring and evaluating the current BGP policy model

Today´s Internet is moving away from the essentially single domain and non-commercial Internet to a multi-domain, combined commercial and not-for-profit Internet. Policy is critical for each domain to protect its business interests. However, the current inter-domain routing protocol, BGP, only provides a policy mechanism where operators have to rely on mutual trust to protect themselves. This paper tries to measure and evaluate the current BGP policy model through passively logging BGP update messages. A policy-server based approach is proposed to address some of the problems discovered from the measurement.
