Immanuel Christian University (UKRIM), Yogyakarta has been established since 1982 under the auspices of the Yayasan Iman Indonesia, while in its development needs are needed for the optimization of every information technology service available at the University in accordance with the times. Based on the results of the questionnaire divided in 2018, results showed that 70% of users, both lecturers, employees and students often complained about the accessibility of streaming, especially https sites, difficulties in batch vouchers, and also the rector did not need a monthly monitoring report that was useful for university accreditation accountability in improving information technology services, especially network fields. In this study optimization was carried out by overhauling the packet data traffic and VLAN HTB based managerial bandwidth network services used by UKRIM university. The reshuffle includes replacing lanes to add new ip address blocks, as well as adding external radius servers and kerio based monitoring. The results of optimization are proven that the value after optimization is better than before optimization, this is evidenced by the throughput of both lecturers and students who change from 35% and 25% to 67% and 44%. From the results of testing the hardware consumption it was found that there was an increase in the consumption of cpu load on the distribution router from 5% to as much as 11%. As for the consumption rate, there is the most significant change from the download and upload side where before the optimization spent a total upload / download of 20,644 / 141 GiB and after optimization spent a total of 127,6/1333,9 GiB.
