Holan Rahmatullah Suhut Nadenggan, Imam Riadi . Analysis of Local Area Network Performance using Quality of Service. International Journal of Computer Applications. 183, 46 ( Jan 2022), 43-51. DOI=10.5120/ijca2022921866
The development of information technology is currently very rapid, especially in computer networks which have become fundamental in all aspects. Analysis of the performance of computer networks, especially network LAN (Local Area Networks) is an effort to assess the quality of the internet network provided. Organizations or agencies that use LAN (Local Area Network) should use a good standard of service quality. Quality of Service (QoS) is one way to determine the performance quality of a network. Quality of Service uses 4 parameters to determine the quality of a network, namely throughput, packet loss, delay, and jitter with good service quality standardization, namely the TIPHON standardization (Telecommunication Internet Protocol Harmonization Over Networks). This research was conducted by assessing the Quality of Service (QoS) in the laboratory computer network before and after a Distributed Denial of Service (DDoS) attack. The process of attacking computer networks using tools LOIC (Low Orbit Ion Cannon)and simultaneously measuring network quality using 4lparameters Quality of Service (QoS). This study aims to determine the quality of a LAN(Local Area Network) network will deteriorate if there is a Distributed Denial of Service (DDoS) attack. The results of theresearch were conducted in accordance with the scenarios and objectives desired. The measurementLAN (Local Area Network)performance, before the attack resulted in a value throughput of 80%, packet loss of 0%, delay of 194.5 ms, and jitter of 0 ms. After the attack resulted in a value throughput of 45%, packet loss of 77.5%, delay of 208.25 ms, and Jitter of 0.75 ms. With a QoS parameter index of 3.75 before an attack, and a QoS parameter index of 2.50 after an attack. The Conclusion is that network attacks can affect the quality of network services and even cause disruption to the network system when the traffic is very high, it is necessary to build Local Area Network security against attacks.
