ANALISIS QUALITY OF SERVICE (QOS) PADA JARINGAN INTERNET DI UNIVERSITAS BINA INSAN LUBUKLINGGAU MENGGUNAKAN METODE HIERARCHICAL TOKEN BUCKET (HTB)

- One problem that is often faced by internet users is slow internet access. Specifically, when there are many users sharing internet bandwidth. This problem can occur because no bandwidth management system is used. Therefore it is necessary to apply the appropriate bandwidth management, one of which is HTB. Bandwidth management with queuing bandwidth lending techniques between classes or users. Which can allocate bandwidth according to user bandwidth requirements according to specified priorities. This study uses data collection methods, by observing and recording directly at the research site (observation), conducting question and answer directly to the source (Interview), and documentation by reading literary books. The results obtained from the measurement of QoS parameters using the HTB method on the Bina Insan University network, it can produce an average QoS index value of 3, and included in the category is good. It can be concluded that the HTB method is feasible to be applied at UNIBI in performing bandwidth management as evidenced by the 3 (three) QoS index value and has a good category.

Traffic Shaping Menggunakan Metode HTB (Hierarchical Token Bucket) pada Jaringan Nirkabel

Perkembangan zaman yang semakin pesat menuntut adanya layanan informasi yang lebih cepat, tepat, dan akurat menjadikan jaringan komputer sebagai kebutuhan utama. Traffic Shaping dengan Quality of Service (QoS) dapat digunakan dalam mengoptimalkan bandwidth suatu jaringan untuk menentukan jenis-jenis lalu lintas jaringan. Metode Hierarchical Token Bucket (HTB) dapat mengimplementasi pembagian trafik yang lebih akurat, dengan bandwidth yang tidak digunakan dapat dioptimalkan oleh pengguna lain. Hasil traffic shaping menggunakan metode HTB menghasilkan rata-rata indeks QoS yaitu 3,75 dan dapat dikategorikan Baik, dibandingkan sebelum menerapkan traffic shaping yaitu rata-rata 2,25 yang dikategorikan Kurang Baik. Berdasarkan hasil pengujian dapat disimpulkan bahwa kinerja jaringan hotspot dengan Traffic Shaping dan Quality of Service (QoS) dapat meningkatkan kualitas jaringan daripada sebelumnya.The development of an increasingly rapid era requires the existence of information services that are faster, more precise, and accurate, making computer networks a primary need. Traffic Shaping with Quality of Service (QoS) can be used in optimizing the bandwidth of a network to determine the types of network traffic. The Hierarchical Token Bucket (HTB) method can implement more accurate traffic sharing, with unused bandwidth being optimized by other users. The results of traffic shaping using the HTB method produces an average QoS index of 3.75 and can be categorized Good, compared to before applying traffic shaping which is an average of 2.25 which is categorized as Poor. Based on the test results it can be concluded that the performance of hotspot networks with Traffic Shaping and Quality of Service (QoS) can improve network quality than before.

Research on QoS Routing Security Algorithm Based on QAODV Protocol

Network control systems (NCS) have higher requirements on QoS index of the network, but MANET can hardly meet the demands of control systems because of its own characteristics. The paper improves AODV and proposes AODV routing protocol QAODV with certain QoS security in combination with NCS and MANET, and expounds routing detection, routing register and routing maintenance. Simulation results show that end-to-end delay and packet loss of QAODV reduces evidently compared with AODV, and the protocol is compatible with AODV. The nodes of 2 protocols can coexist and work normally in the same network.
