Network Tasks Optimalization
Dražil, Jan ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
Nowdays, when we are running out of public IPv4 addresses, we rely on techniques that at least postpone their complete exhaustion. One of these techniques is a network address translation (NAT). Internet providers require the highest possible bandwidth from devices that perform this task. This thesis compares NAT DPDK, built on top of DPDK framework, with freely available alternatives. This work also extends NAT DPDK with Application-Level Gateway support.

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)
