Automating Network System Configurations for Vendor-Specific Network Elements

Abstract [en]

In present day, telecommunications stakeholders have not yet fully automated hardware configurations. Network configuration and reconfiguration is a repetitive, time consuming, and error prone process. To address this problem this bachelor thesis is going to shed light on the benefits of an automated configuration and topology verification process. To this end, a proof of concept system, Enna, has been developed in a case study together with an ISP stakeholder. Enna reads the current network state, applies predetermined configurations loaded from text-files, and automatically verifies the network state. The goals of this thesis are as follows: development of Enna to illustrate the simplicity in the implementation, compare the automated network reconfiguration to a fully manual one, and finally discuss potential benefits or problems in switching to an automated network configuration. Since this thesis is carried out in collaboration with an ISP working with Cisco IOS XR devices, Enna is only tested for basic network protocols common in such environment, the conclusions drawn in this paper are therefore only applicable to such context.

Abstract [sv]

I dagens läge tillämpar inte telekommunikationsintressenter automatiserade processer som standard. Nätverkskonfigurering och omkonfigurering är en repetitiv, tidskrävande och felbenägen process. För att adressera detta problem kommer denna kandidatavhandling belysa fördelarna med en automatisk nätverkskonfiguration och verifieringsprocess. För detta ändamål har ett system, Enna, framtagits som ett bevis på konceptets ändamålsenlighet. Enna läser aktuell nätverksstatus, tillämpar förutbestämda konfigurationer som laddas in från textfiler, och verifierar nätverkstatus automatiskt. Målet för detta examensarbete lyder: utveckling av Enna för att illustreara simplisteten i framtagandet, jämföra en automatisk nätverkskonfiguration med en manuell , och slutligen diskutera fördelar och problem vid byte till en automatiserad närverskonfiguration. Eftersom att detta examensarbete genomförts i samarbete med en ISP som arbetar med Cisco IOS XR-enheter, och Enna endast testats med grundläggande närverksprotokoll vanliga för dessa miljöer, kommer slutsatserna i detta dokument endast vara tillämpbara i dylikt sammanhang.
