Routing policies and real paths in the Internet
Hlaváček, Tomáš ; Peterka, Jiří (advisor) ; Kruliš, Martin (referee)
Routing policies are now represented by RPSL and by its evolutionary extension called RPSLng. These languages can be used for describing unique routing policy of each autonomous system. Experience shows that even though there are translation tools from RPSL and RPSLng to configuration formats of commonly used routers, the actual network configuration is rarely generated from RPSL sources and routing policy is then perceived as marginal paperwork, which often does not reflect the real network settings. There will be most likely a need for RPSL format change in order to remedy the discrepancies. To support this I present long-term measurements of inaccuracies in routing policies compared to real paths in the Internet. I also present a list of the most frequent problems, and I offer suggestions, how to reform RPSL to improve situation in the long term. Powered by TCPDF (www.tcpdf.org)
