V pričujočem diplomskem delu sem predstavil srednje veliko korporativno računalniško omrežje in problematiko njegove upočasnjenosti, ki je ovirala vsakodnevno delo v podjetju. Analiza prejšnjega stanja je pokazala, da je bil vzrok za pogosto daljše zakasnitve in slabo izkoriščenost internetne povezave preobremenjen robni strežnik. Za uspešno rešitev sem moral premišljeno načrtovati, pripraviti in v omrežje implementirati ustrezen robni strežnik. Pri tem sem s predstavljenimi postopki uspešno odpravil vse težave, omrežje ustrezno optimiziral in hkrati predlagal tudi smernice za dodatne izboljšave v prihodnosti. Primerjava stanja pred posegom in po njem je pokazala, da robni strežnik sedaj omogoča vsaj 10-krat hitrejši pretok in količino podatkovnega prometa s skoraj nespremenjeno porabo sistemskih sredstev, ki je bila pred tem glavni razlog vseh težav. Tako je izkoristek razpoložljive internetne povezave, ki je bil pred optimizacijo manj kot 10-odstoten, sedaj skoraj 100-odstoten. Stabilno delovanje omrežja se kaže tudi s tem, da se je kljub veliko večji obremenitvi omrežja povprečje zakasnitev zmanjšalo za skoraj 30-krat.

| Abstract: |
|---|
In this thesis I have presented medium sized corporate network and issues with its slow performance which obstructed company everyday work. Previous state analysis showed that the reason for high latencys and poor network utilization was an overloaded edge server. Successful solution required a thoughtful design, prepararation and implementation of appropriate edge server. With featured procedures I have successfully solved all problems and properly optimized the network. At the same time I suggested further improvement guidelines in the future. State comparison before and after showed that the edge server now allows at least 10-times higher troughput speed and amount of data traffic with almost constant consumption of system resources, that previously caused all main problems. Network utilization is now almost at 100 percent, compared to less then 10 percent in previous state. Stable network performance is also reflected by a 30-times lower average latency despite of much larger network load.
