<p align="center"><strong>ABSTRACT</strong></p><p><em>The internet as a data transmission backbone has security threats in sending data. To overcome the security problem of every data communication that is done through a public network (public network), then a connection is needed that requires a connection between workstations running privately, so that only workstations that have access can connect, by using a virtual private network or VPN. The advantage of a VPN is that data sent over an encrypted VPN is quite safe and the secret is maintained even through the internet network because the data sent will go through the tunnel. Tunneling itself is a method for transferring data from one network to another by using a veiled internet network. Two protocols can be chosen in a VPN, namely Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP). However, the performance of each of these protocols is unknown yet. To find out the performance of the two protocols we need a test with a simulation method. Using a Mikrotik router and Wireshark application with Quality of Service (QoS) parameters consisting of Packet Loss, Delay, and Throughput on 2 clients connected to the mikrotik router and each client uses a different protocol. All clients will stream videos simultaneously to get a data packet capture. The test results will be grouped into four categories, namely bad, moderate, good and very good. It is expected that data will be able to show the quality of service of both protocols. so that it can be used as a reference in the selection of VPN protocol to be used.</em></p><p><strong><em>Keywords: </em></strong><em>Quality of Service, PPTP, L2TP</em></p><p align="center"><strong>ABSTRAK</strong></p><p><em>Internet sebagai backbone pengiriman data memiliki ancaman keamanan dalam pengiriman data. Untuk mengatasi masalah keamanan setiap komunikasi data yang dilakukan melalui jaringan publik (public network) maka diperlukan suatu mekanisme yang memungkinkan koneksi antar workstation berjalan secara private, sehingga hanya workstation yang memiliki akses yang dapat saling terhubung, dengan cara memanfaatkan virtual private network atau VPN.</em> <em>Keuntungan VPN adalah data yang dikirimkan melalui VPN terenkripsi sehingga cukup aman dan rahasianya tetap terjaga meskipun melalui jaringan internet, karena data yang dikirim akan melalui tunnel.</em> <em>Tunneling sendiri merupakan metode untuk transfer data dari suatu jaringan ke jaringan lain dengan memanfaatkan jaringan internet secara terselubung. Terdapat dua protokol yang dapat dipilih dalam VPN yaitu Point to Point Tunneling Protocol (PPTP) dan Layer 2 Tunneling Protocol (L2TP). Akan tetapi belum diketahui performa dari masing – masing protokol tersebut. Untuk mengetahui kinerja dari kedua protokol tersebut diperlukan sebuah pengujian dengan metode simulasi. Menggunakan router mikrotik dan aplikasi Wireshark dengan parameter Quality of Service (QoS) yang terdiri dari Packet Loss, Delay, dan Throughtput pada 2 client yang terhubung ke router mikrotik dan setiap client akan menggunakan protokol yang berbeda. Semua client akan melakukan video streaming secara bersamaan untuk mendapatkan capture paket data. Hasil pengujian akan dikelompokkan menjadi empat kategori, yaitu kategori buruk, sedang, bagus dan sangat bagus. Diharapkan akan dihasilkan sebuah data yang dapat menunjukkan kualitas dari layanan kedua protokol tersebut. sehingga dapat dijadikan acuan dalam pemilihan protokol vpn yang akan digunakan.</em></p><strong><em>Kata kunci:</em></strong><em> Quality of Service, PPTP, L2TP</em>

Computer networks are one of the main parts in the telecommunications system. To support reliable network technology, a centralized network is needed so that network traffic can be managed more easily. Software-Defined Network (SDN) technology is a centralized network that provides a separation between control planes and data planes in different systems. This study discusses the optimization of network management at the University of Riau (UNRI) using SDN. Optimization is done by designing a UNRI computer network in the form of SDN then simulated using the Mininet. Quality of Service (QoS) analysis is performed from the measurement results using Wireshark. The network simulation results give a delay value of 0.506 ms, 0% packet loss, the throughput of 590,392 Mb / s and jitter of 0.093 ms. The SDN network provides better delay and jitter performance compared to conventional UNRI networks with a delay value of 13,874 ms, 0% packet loss, 635.1 Mb/s throughput and 2.6 ms jitter. UNRI's SDN network design is worth considering because it has better QoS values, delay, and jitter below ITU standards and conventional networks.

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.
