Abstract

PT Aplikanusa Lintasarta is a company engaged in the internet service provider. Lintasarta already has a voip network before but has problems, namely the qualityof service of VoIP services is not guaranteed and there is also no server that functions to block SIP domains by adding certain patterns to avoid Toll fraud. Current bandwidth limitations can cause network traffic to overload. IETF(Internet Engineering Task Force) has a standard to meet QoS needs, namelyDiffserv which is able to classify packets according to needs. However, diffservalone is not enough, when there is an accumulation of packets, the packets that accumulate will be dropped, therefore the addition of WRED as a solution to thedropping is by applying the threshold system. The WRED algorithm is able toprovide a good effect, the test results of VoIP services by adding WRED canreduce packet loss by about 15% and delay 10% Diffserv-WRED can alsomaximize throughput, which is 2% compared to diffserv and also reduce jitter byabout 8% compared to only applying diffserv. only and also the application of theTURN-Server with a call policy pattern is able to block calls that have thepotential to toll fraud that make calls continuously or with certain domains, this isable to maintain the condition of VoIP resources such as call managers so that their availability is maintained due to avoidance of exploitation. Key words: research, guidance, computer science, universitas mercu buana PT Aplikanusa lintasarta merupakan perusahaan yang bergerak dibidang internet service provider. Lintasarta sudah memiliki jaringan voip sebelumnya namunmemiliki permasalahan yaitu belum terjamin nya Quality of service dari layananVoIP dan juga belum adanya server yang berfungsi untuk melakukan blockingSIP domain dengan menambahkan pattern terntetu agar terhindar dari Toll fraud. Keterbatasan bandiwdth saat ini bisa menyebabkan terjadinya beban berlebih padasebuah traffic jaringan. IETF (Internet Engineering Task Force) memiliki suatustandard untuk memnuhi kebutuhan QoS yaitu Diffserv yang mampumengklasifikasi packet sesuai kebutuhan. namun diffserv saja tidak cukup, ketikaterjadi penumpukan packet maka packet yang menumpuk tersebut akan didropoleh karena itu penambahan WRED sebagai solusi dari dropping tersebut denganmenerapkan sistem treshold. algoritma WRED mampu memberikan pengaruhyang baik, hasil pengujian layanan VoIP dengan menambahkan WRED mampumengurangi packet loss sekitar 15% dan delay 10% Diffserv-WRED juga bisamemaksimalkan Throughput yaitu 2% dibanding diffserv dan juga mengurangi jitter sekitar 8% dibandingkan jika hanya menerapkan diffserv saja dan jugapenerapan TURN-Server dengan call policy pattern mampu memblock panggilanyang berpotensi toll fraud yang melakukan panggilan terus menerus maupundengan domain terntetu, hal ini mampu menjaga kondisi dari resource VoIPseperti call manager agar ketersediaanya terjaga dikarenakan terhindar dari exploitasi.
