Abstract

Tvrtke i organizacije koje danas provode digitalnu reformu postavljaju suvremenim mrežama nove i sve strože zahtjeve. Dodavanjem novih usluga i za njih potrebne mrežne infrastrukture, s ciljem zadovoljenja novih zahtjeva mreže, mrežnim se administratorima uz uobičajene svakodnevne zadatke upravljanja i optimizacije mreže znatno povećava opseg posla. Radi pojednostavljenja procesa implementacije novih mrežnih uređaja, unutar SD-Access koncepta razvija se rješenje automatizacije konfiguracije, Zero Touch Provisioning (ZTP). ZTP je moguće primijeniti i unutar tradicionalne arhitekture mreže što je i predmet ovog diplomskog rada. Inicijalni korak bila je izrada mrežnog okruženja primjenom alata Emulated Virtual Environment Next Generation. Kao eksperimentalno okruženje korištena je topologija mreže po uzoru na stvarna poslovna okruženja. U sklopu ovakve topologije definirani su potrebni poslužitelji i na različitim mrežnim lokacijama pridružena dva mrežna uređaja koji podržavaju ZTP model. Također, za provedbu procesa automatizacije bilo je potrebno izraditi skriptu u programskom jeziku Python. Pokretanjem predmetnih uređaja preuzima se skripta s postavljenog poslužitelja. Skripta se potom izvodi, a kao rezultat izvođenja primjenjuje se odgovarajuća konfiguracija na tim uređajima. Nakon provedbe ZTP modela i pregleda rezultata, potencijal koji omogućuje ovakvo rješenje u mrežama mnogo većih razmjera je evidentan. Primjena ovog modela zasigurno bi omogućila pojednostavljenje procesa instalacije novih uređaja na mrežu. Osim toga, model osigurava znatnu uštedu vremena potrebnog za instalaciju kao i financijskih sredstava, a naposljetku smanjuje i vjerojatnost pojave pogreške pri konfiguraciji. Rezultati ovog rada mogu pridonijeti boljem razumijevanju procesa implementacije ZTP modela s ciljem raširenije primjene istog.

Abstract (english)

Nowadays, companies and organizations that are implementing digital reform are placing new and increasingly stringent requirements on modern networks. By adding new services and the necessary network infrastructures in order to meet the new network requirements, network administrators, in addition to the usual daily tasks of network management and optimization, get significant increase of the scope of work. To simplify the process of implementing new network devices, a configuration automation solution Zero Touch Provisioning (ZTP) is being developed within the SD-Access concept. ZTP can also be applied within the traditional network architecture which is the main subject of this thesis. Initial step was creating a network environment using the Emulated Virtual Environment Next Generation tool. As an experimental environment, a network topology modelled on real business environments was used. Within this topology the required servers were defined and two devices which support the ZTP model were associated at different network locations. Also, to implement the automation process, it was necessary to create a script in the Python programming language. At startup, the two devices download the script from the defined server. The script is then executed, and as a result of this process the appropriate configuration is applied to these devices. After the implementation of the ZTP model and the review of the results, the potential provided by such solution in networks of much larger scales is evident. The application of this model would certainly simplify the process of installing new devices on the network. Besides, it would also provide significant savings in both installation time and financial resources, ultimately it would reduce the likelihood of configuration errors too. The results of this paper can contribute to the better understanding of the process of implementation of the ZTP model and therefore to its more widespread application in the future.
