A component of automation system for routing operation in autonomous systems exchange point

摘要

As an automation system of routing operation in exchange point of the Autonomous System, RPSL (Routing Policy Specification Language) and IRR (Internet Routing Registry) system have been developed. Although IRR has been designed to manage routing policies described in RPSL this system is not extensively used in many routing operations. The maintainers of ASes are registering their own routing policies without checking consistency between the policies of other ASes. As a result, this prevents increasing the utilization of IRR. Inconsistency between routing policies results in unexpected routing. In this paper, we propose a system which detects these inconsistencies and notifies the maintainer to correct them. The algorithm for detecting inconsistencies are presented.
