“…Using Riverbed modeler academic version 17.5 to evaluate voice quality in VoIP experiments, these different scenarios were studied by simulating a VoIP network and its performance was studied and analyzed under the different scenarios. This is to guide researchers and designers to design and deploy a network for VoIP services and also guide network operators to choose speech compression techniques that will provide better voice quality" [9].…”

Designing and deploying an efficient and cost effective network that will satisfy end users requires a careful consideration of the different network devices that are available and selecting network parameters that will guarantee optimum performance. In this study, Riverbed modeling software was used to simulate and study the effects of varying different network parameters and devices on the performance of a local area network (LAN). Starting off with the designated Simple Network and Busy Network, the network parameters were varied for other scenarios to investigate the effects of network background utilization, link type, as well as the number of servers. Results from the simulation show that for a local area network, the web server demonstrated the highest CPU utilization. While increasing the background utilization of the network increased the remote server access time, FTP get download time, and HTTP request page response time, replacing the three servers with a single server did not have any significant impact on the CPU utilization. Further results from the simulation show that using cables enhanced the data transmission rate, and rather than deploying multiple servers, effective selection and distribution of network services can be used to achieve optimum network performance using a single server. This is achieved by striking a balance between frequently utilized network services and non-frequently utilized network services.

El presente trabajo de investigación dedicado a la Las redes WAN y su importancia para los ORDENADORES debería ser hoy en día una inquietud importante para cualquier empresa organización donde se beneficia en el ámbito tecnológico y laboral Las redes WAN se utilizan principalmente para enviar información a grandes distancias y mantener interconectadas ciudades, países y continentes, permitiendo un flujo de información de alta velocidad.La generalidad de la computadora personal y de la red hace ha dado lugar a posibilidades para poder acceder a la información de actual, podemos cargar aplicaciones desde cualquier punto, compartir y recibir mensajes de cualquier parte del mundo, todo tan solo desde un equipo y en segundos. Los equipos modernos en la actualidad gracias a su complejidad nos permiten las redes y es tan eficaz debido a la diversidad de sus componentes. A nivel mundial se ha implantado una red de computadoras que se considera como uno de los más grandes avances de la tecnología en las últimas décadas. Su importancia más relevante, es que mantienen la información en constante movimiento y al alcance de todos, ya que sin estas redes, la información estaría ubicada solamente en las redes locales y no pudieran ser accedidas por usuarios que se encuentren a kilómetros de distancia. Sin las redes WAN, no existiría Internet ni acceso público a la información, es por esta razón, que es muy importante la presencia de redes WAN en el mundo.

Modern technology is essential for all healthy, economic, and educational sectors. Using modern technology involves high-performance networks in terms of quality of service (QoS) parameters such as delay, throughput, bandwidth, and security. A campus network involves wire and the wireless environment with and without virtual local area network (VLAN) technology has been simulated using optimized network engineering tools (OPNET). The simulation model includes four scenarios that involve heavy-loaded File transfer protocol (FTP) and web browsing applications with two logical groups of users. The simulation results show that the VLAN overcome LAN networks in terms of bandwidth and security. This has been done by reducing the throughput in both sending and receiving levels to the confidential servers. The VLAN has also reduced the broadcast domain which results in a high-power efficiency. Moreover, the VLAN network technology has been proved to have lower values of delay in transferring files and packets than LAN network technology. In addition, VLAN technology generally has been decreased values of throughput regardless of the way of connection between servers and workstations. This, in turn, allows taking advantage of wireless connection features in terms of flexibility of installation and speed of configuration.
