Layanan multimedia melalui jaringan internet seperti, teknologi Voice over IP (VoIP), video on-demand (VoD), IP television (IPTV), konferensi video beresolusi tinggi dan beberapa aplikasi real time, akhir-akhir ini trafiknya terus meningkat. Layanan multimedia memiliki persyaratan QoS yang tinggi terhadap loss, delay, jitter, dll. Ada banyak faktor yang menyebabkan penurunan kualitas layanan multimedia pada jaringan seperti penggunaan protokol routing dan termasuk juga mekanisme keamanan yang digunakan pada jaringan. Memiliki sistem komunikasi yang aman itu penting, baik untuk urusan bisnis atau pribadi, tetapi penting juga untuk menjaga kinerja dari layanan karena mekanisme keamanan memiliki efek menurunkan kualitas layanan multimedia. Penelitian ini ini membahas pengukuran dan analisa pengaruh routing protokol dan mekanisme keamanan pada kualitas layanan multimedia dengan menggunakan simulai aplikasi atau layanan VoIP sebagai ujicoba. Berdasarkan hasil simulasi didapatkan hasil pengaruh dari penerapan mekanisme keamanan pada layanan VoIP delay untuk komunikasi VoIP dengan media transmisi yang secure dan delay pada proses pensinyalan meningkat 4,22%.

Packet scheduling and buffer management are the two important functions adopted in networks design to ensure the Quality of Service (QoS) when different types of packets with different needs of quality share the same network resources. The Packet scheduling policy determines packet service priorities at the output link, it can reduce packet delay and delay jitter for high-priority traffic. The buffer management involves packet dropping and buffer allocation. The overall goal of such schemes proposed in High Speed Downlink Packet Access (HSDPA) is to take advantage of the channel variations between users and preferably schedule transmissions to a user when the channel conditions are advantageous; it does not take in consideration the characteristics of the flows composing the transmitted traffic to the user. This paper compares two queue management mechanisms with thresholds applied for packets transmitted to an end user in HSDPA network. Those mechanisms are used to manage access packets in the queue giving priority to the Real Time (RT) packets and avoiding the Non Real Time (NRT) packets loss. The authors show that the performance parameters of RT packets are similar in the two mechanisms, where as the second mechanism improves the performance parameters of the NRT packets.

User Coverage

Video streaming adalah aplikasi yang dapat melayani kebutuhan user akan data yang bersifat real time. Dengan adanya teknologi wireless LAN, user akan semakin dimudahkan dalam mengakses informasi seperti video streaming kapan saja dan di lokasi mana saja.Penelitian ini ditujukan agar dapat memperlihatkan hasil video streaming dari beberapa lokasi dalam lingkungan kantor Indosat. Dalam percobaan ini menggunakan beberapa perangkat antara lain satu buah server streaming, satu klien yang menggunakan laptop dan AP yang memang sudah ada dalam jaringan LAN Indosat serta skenario lokasi yang telah ditentukan sebagai tempat pengambilan data. Kemudian dilanjutkan pada tahap pengamatan sistem dengan melakukan peng-capture-an paket untuk mendapatkan data berupa throughput, delay, jitter, dan packet loss ratio dari tiap-tiap lokasi yang telah ditentukan.Hasil Penelitian ini, dengan adanya perbedaan lokasi mengakibatkan perbedaan dari kualitas video streaming berdasarkan parameter- parameter yang telah didapat pada percobaan.Kata Kunci : video streaming, wireless LAN, user, coverage

Real-time transferring of the haptic sense over the Internet is quite a challenging task. This paper outlines the proposed protocols for transferring haptic streams over the Internet. Moreover, it describes the Quality of Service requirements that a network has to fulfill in order to successfully use haptic interfaces with high update rates over the Internet. Extensive simulations and experiments for the performance evaluation of transport protocols for real-time transferring haptic data are carried out. Complements between simulation and real world experiments are discussed. The metrics that are measured for the performance evaluation are delay, jitter, throughput, efficiency, packet loss and one proposed by the authors, packet arrival deviation. The simulation tests reveal which protocols could be used for the transfer of real-time haptic data over the Internet.
