Resumen Voz sobre IP, VoIP, es uno de los servicios con mayor desarrollo bajo plataformas inalámbricas; actualmente se ha iniciado su implementación como alternativa frente a la PSTN (red pública conmutada). El interés por VoIP radica en su relación costo-beneficio, ya que las organizaciones pueden utilizar la misma plataforma de su red de datos para transmitir voz. Por lo anterior, es importante que la organización tenga claro que, para garantizar el buen funcionamiento del servicio de VoIP, es decir para ofrecer QoS, se debe realizar la medición de parámetros que afectan la calidad del servicio como lo son: el retardo, la variación del retardo, el ancho de banda y la pérdida de paquetes. Este artículo analiza y valida los parámetros de QoS necesarios para garantizar el buen funcionamiento del servicio de VoIP sobre la red inalámbrica del campus de la Universidad Icesi. Se realizan pruebas en diferentes escenarios para mostrar que no solo factores como el retardo, y su variación, influyen en la calidad de servicio, sino que también la intensidad de la señal que recibe el cliente desde los puntos de acceso.Palabras Clave: Voz sobre IP, Calidad de servicio, Pérdida de paquetes, Retardo, Variación del Retardo, Intensidad de Señal. Abstract VoIP is one of the services that has been developing over under this type of wireless platforms and today has begun to implement as an alternative to the PSTN (Public Switched Telephone Network). The interest in VoIP is its cost-benefit ratio, and that organizations can use the same platform for their data network to transmit voice. Therefore it is important that the organization is clear that to ensure the smooth operation of the VoIP service, ie provide QoS, you must perform the measurement of parameters that affect the quality of service such as: delay, jitter, bandwidth, packet loss. In this paper we analyze and validate the QoS parameters needed to ensure the smooth operation of VoIP over wireless network on the Icesi University campus. We performed a series of tests in different scenarios to show that not only factors such as delay and jitter influencing the quality of service, but also the client signal strength received from of the AP (Access Point).Keywords: Voice over IP, Quality of service, Packet Loss, Delay, Delay variation, signal intensity.

This article describes the IPTV system, as well as its implementation methods and related protocols. The concept of IPTV includes both real-time television and recording television, the so-called VoD. In real time, streaming data is sent using only the RTP protocol and in addition to it, the RTSP protocol is used for streaming VoD. In addition, methods for measuring QoS parameters are analyzed, considering practical applications for estimating IPTV traffic parameters. An important feature of providing quality IPTV services is a high level of quality of service. Also, in theory, an Internet connection model with insufficient network bandwidth is considered. The following characteristics are taken into account: bandwidth, one-way delay, inter-packet jitter, the number of lost packets, the number of duplicated packets, packets with errors, and damaged packets. A reordering issue is mentioned. In addition, two important QoS parameters for VoD are measured: START delay and PAUSE / RESUME delays. Service messaging is considered while providing IPTV service. The maximum, average, and minimum values for the network quality of service parameters are found.

<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.
