“…Different types of links and topologies were applied among WLAN subnets while the gateway was changed to measure quality of services (QoS) parameters for the different scenarios investigated. Findings from the study reveal that in terms of WLAN delay, WLAN load, FTP download response time, as well as HTTP object response time, the FDDI hybrid ring scenario produces better performance than the FDDI Hybrid Star Scenario" [6].…”

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.

“…OPNET modeler is a simulation program that can design, measure performance, and design a communication network model so that it is often used in the academic world, especially those related to communication networks. OPNET can simulate various network technologies such as internet protocol (IP), global system for mobile (GSM), WiMax, and Zigbee networks [10].…”

<span>A quality network infrastructure is a user demand for the increment of traffic nowadays. Due to data traffic congestion, a network’s service quality cannot fulfill the user demand, especially for streaming-type traffic. For this, an appropriate queuing method can be a convenient solution for network congestion at the time of picking traffic load. In this paper, a simulation was conducted using the OPNET application to examine the feasibility of three types of queuing methods, namely first in first out (FIFO), priority queuing (PQ), and weighted fair queuing (WFQ). During the simulation, several important parameters such as delay, throughput, and response time are considered as performance metrics and compared among four types of applications as file transfer protocol (FTP), hypertext transfer protocol (HTTP), voice over internet protocol (VoIP), and video conferencing. According to the result, it is observed that WFQ provides comparatively improved results than PQ and FIFO.</span>

“…Therefore, along with technological advances, the design of a wireless network security system connected to the internet [17,18] must be well planned and understood to effectively protect the resources on the network and minimize attacks by attackers or hackers [19]. Due to the lack of awareness of administrators or people who act as admins in running the system, while external factors can occur due to weak systems made (configuration) and the large level of cybercrime [20].…”

Advances in information and communication technology continue to grow over time. This causes significant changes in social, economic, and political conditions. One company that requires strong network security is PT PLN (Perusahaan Listrik Negara) Persero, which is a leading energy company in Indonesia. In this case, the need to evaluate network security at PT PLN is very important. This evaluation will help identify vulnerabilities and security gaps that exist in PT PLN's network infrastructure. This network security evaluation using the Penetration Testing Execution Standards (PTES) method can provide an overview of the vulnerabilities or weaknesses of the network system at PT PLN UP2D S2JB which has quite a lot of gaps to exploit. This is evidenced by the results of fifteen tests conducted, only two of which failed, namely in the type of attack The Rogue Access Point. The results of Penetration Testing are very necessary and important as feedback for system managers in fixing existing vulnerability gaps.
