NetReview: Detecting When Interdomain Routing Goes Wrong
Source: Princeton University
Despite many attempts to fix it, the Internet's interdomain routing system remains vulnerable to configuration errors, buggy software, flaky equipment, protocol oscillation, and intentional attacks. Unlike most existing solutions that prevent specific routing problems, the approach is to detect problems automatically and to identify the offending party. Fault detection is effective for a larger class of faults than fault prevention and is easier to deploy incrementally. To show that fault detection is useful and practical, this paper presents NetReview, a fault detection system for the Border Gateway Protocol (BGP).
