Abstract

Kako bi se ostvarila mrežna arhitektura koja će moći odgovoriti na današnje zahtjeve korisnika, nužna je integracija SDN mreža te tehnologija virtualizacije. Dvije ključne stvari u kontekstu SDN-a i mrežne virtualizacije su osigurati otpornost na kvarove kontrolne ravnine raspodijeljene između više instanci SDN upravljačkih uređaja te efikasno ugraditi virtualnu mrežu povrh fizičke infrastrukture. Performanse kontrolne ravnine, uključujući pouzdanost, uvelike ovise o rasporedu instanci upravljačkih uređaja i hipervizora. U okviru ovog rada razrađen je, matematički opisan i riješen problem raspoređivanja upravljačkih uređaja i hipervizora za preživljavanje programski upravljanih mreža u optimizacijskom alatu IBM ILOG CPLEX. Provedeno je vrednovanje implementiranog modela na odabranim studijskim slučajevima.

Abstract (english)

The integration of SDN network with virtualization technologies is essential to form network architecture which will be able to answer user requirements nowadays. Two key issues regarding SDN and network virtualization are to ensure resilience to failures of control plane distributed among multiple instances of an SDN controller and to efficiently embed a virtual network on top of the physical infrastructure. Performances of control plan, including reliability, greatly depend on controller and hypervisor placement. In this work, a problem of controller and hypervisor placement for survivability of software-defined networks is elaborated, mathematically formulated and solved in the IBM ILOG CPLE optimization tool. Evaluation of solution is carried out on selected case studies.
