MANAJEMEN QOS UNTUK LAYANAN VOIP PADA WLAN

QOS MANAGEMENT FOR VOIP SERVICE OVER WLAN

Author :
Hanafi, Mahmud 




ABSTRAK

Teknologi wireless local area network WLAN merupakan teknologi yang berkembang pesat saat ini. Seiring dengan hal itu layanan multimedia mulai diterapkan pada jaringan ini salah satunya adalah layanan Voice over Internet Protocol VoIP. Dalam aplikasinya layanan VoIP akan berbagi sumber daya jaringan dengan layanan data lainnya. Untuk itu dibutuhkan suatu mekanisme quality of service QoS pada jaringan WLAN sehingga layanan VoIP dapat berjalan dengan kualitas yang baik bersama layanan data lainnya. Pada tugas akhir ini dilakukan studi mengenai manajemen QoS dan kemudian dilakukan implementasi pada jaringan WLAN dengan teknik priority queuing untuk mendukung layanan VoIP. Permasalahan yang dibahas dalam tugas akhir ini adalah bagaimana melakukan manajemen QoS sehingga kualitas layanan VoIP dapat terjaga meskipun dalam jaringan tersebut juga terdapat trafik data lainnya. Berdasar hasil pengukuran dari implementasi sistem yang telah dilakukan didapatkan parameter QoS yang paling berpengaruh pada kualitas suara adalah packet loss dimana kualitas suara mulai menunjukkan penurunan yang signifikan saat dilakukan pembebanan UDP sebesar 2Mbps dan 4Mbps dimana tanpa dilakukan manajemen QoS didapatkan packet loss sebesar 163 dan 401 . Manajemen QoS pada access point berhasil menurunkan packet loss menjadi 19 dan 119 untuk pembebanan UDP sebesar 2Mbps dan 4Mbps.


ABSTRACT

Today wireless local area network WLAN is the technology which grows rapidly. Along with this multimedia services start to be implemented in this network one of them is the voip service. In the real world application the voip service will share the network resources with the other data services. In order to reach that we need a quality of service qos mechanism in the WLAN network so the voip service could run in a good quality with the other data services. In this final project a study about qos management was done and then the implementation in the WLAN network was also been done with the priority queuing technique which support voip service. The subject which is discussed in this final project is how to do the qos management in order to keep the quality of the voip service although there are other data traffic in the network. Based on the result of the measurement toward the system implementation which has been done there is a qos parameter which affect the most to the voice quality it is the packet loss where voice quality start to show a significant decrease when there was a UDP load as big as 2Mbps and 4Mbps whereas without the qos management the result of packet loss was 16.3 and 40.1. QoS management on the access point had been successfull in increasing in the packet loss into 1.9 and 11.9 for the UDP load as big as 2Mbps and 4Mbps.
