ANALISIS QUALITY OF SERVICE PADA PENGGUNAAN IP TELEPHONY DI PUSAT TEKNOLOGI INFORMASI DAN PANGKALAN DATA (PTIPD) UIN SUNAN KALIJAGA

In the development of technology namely with the advent of the internet, the internet is a network that is interconnected using global system standards Transmission Control Protocol / Internet Protocol Suite (TCP / IP) as a packet exchange protocol to serve billions of users around the world. The internet has given birth to a new technology called IP Telephony, IP Telephony is a technology that is capable of passing packet traffic, video and data in the form of a packet through an IP network. As a first step in an effort to improve the quality of network services in the use of IP Telephony, measurement results are needed that represent the average value of Internet network service performance against changes in QoS parameter values in the use of IP Telephony at the Information Technology Center and Data Base UIN Sunan Kalijaga. In this study action research method is applied, this research method refers to the QoS parameters. QoS mechanisms on the network that determine that applications or services can operate in accordance with established service quality standards. QoS parameters which consist of delay, jitter, throughput and packet loss. The results of the IP Telephony analysis at the Information Technology Center and Data Base of the UIN Sunan Kalijaga received results that were not all maximal. Testing delay is 0.18 milliseconds which if categorized according to the standardization of TIPHON is very good. Jitter testing is 0.356 milliseconds which if categorized according to the standardization of TIPHON is good. Testing packet loss is 0% according to the standardization of TIPHON is very good. Throughput testing has a quality level of 1% which if categorized according to the standardization of TIPHON is classified as bad
