Abstract

EIGRP (Enchanched Interior Gateway Routing Protocol) memiliki sistem pembangunan protocol routing digunakan untuk mengkalkulasikan dan membangun sebuah routing table dan untuk memastikan sebuah jalur untuk sebuah network dan menyediakan sebuah loopless routing environment agar membantu mengirimkan sebuah packet ke sebuah jaringan. Routing loopless dapat terjadi ketika update informasi tentang hilangnya suatu rute, karena hal ini tidak dapat diterima oleh semua router pada network. Hal ini, bisa terjadi karena paket update mengalami kerusakan (corrupt) atau terbuang (dropped). Sehingga router-router yang menerima update akan beranggapan saat ini terjadi masalah pada network. Akhirnya router-router tersebut memberikan informasi yang salah kepada neighbor tentang kondisi rute yang diketahuinya. Manakala router asal (pengirim) tidak menerima paket dari neighbor dalam jangka waktu tertentu, maka router asal (pengirim) akan kembali mengirim paket update. Metode IP routing menggunakan EIGRP dan EIGRP DUAL pada jaringan rekayasa sistem sesuai dengan teorinya didalam sekenario satu dan skenario dua, setiap skenario terdapat tiga tabel yang terpisah yaitu tabel tetangga, tabel topologi dan tabel routing. nilai metric digunakan sebagai acuan untuk menentukan pilihan jalur terbaik ke alamat network tujuan. Nilai metric ditentukan menggunakan dua parameter yaitu bandwith dan delay, kemudian hasil jaringan menggunakan sistem rekayasa di implementasikan langsung terhadap interface perangkat sebenarnya, baik dalam mengirim data dari yang dilakukan pada skenario satu dan dua sehingga mendapatkan kinerja EIGRP dan DUAL EIGRP dalam menentukan besaran nilai bandwith dan delay yang dihitung dalam seksama sehingga jalur yang ditentukan sesuai dengan konsep yang diinginkan. Kesimpulan dari hasil parameter tersebut jalur kedua dari skenario dua lebih baik kemampuannya dalam mengirimkan data sebesar 1,14 Mbps dengan delay (respontime) sebesar 1 s.

Abstract

Network optimization is one of the important aspects that aims to improve the performance, efficiency and reliability of network systems and security on the network, but if the optimization is not carried out effectively it will pose a security threat to the network, one of the real threats is DdoS Attack, DdoS attack is a dangerous attack because this attack can paralyze the network server,  Therefore, optimization needs to be carried out in the KP Room in order to avoid the threat of DdoS attacks, so the initial stage of this research will test the network to find out how optimal the network is in the KP room so that optimization is needed. The research method used is NSIT, which includes collection, examination, analysis, and reporting, the results after the research is carried out where, on the network in the kp room after testing at the examination stage and then by identifying the test results, it can be concluded that the network is not optimal enough against DdoS attacks and connection type attacks which, The optimization step taken is to apply a Tarpit firewall on the router. The implementation of Tarpit Firewall successfully overcomes DdoS attacks by slowing down incoming connections and stopping attacks, thereby improving network security from Port Scanning, DDoS, and Brute force attacks.

Abstract

Indonesia is one of the countries with a high level of dependence on cellular communication systems. Along with rapid technological advancement, cellular networks in Indonesia continue to develop intensively, resulting in increasingly competitive service provision. The 4G Long Term Evolution (LTE) network is currently the most widely used mobile technology due to its superior data transmission speed and capacity, with download speeds reaching up to 300 Mbps and upload speeds up to 75 Mbps under optimal conditions. This study aims to analyze and compare the Quality of Service (QoS) of 4G LTE networks provided by Telkomsel, IM3, and 3 (Three) in Prabumulih City, Indonesia. The analysis was conducted using the OpenSignal, Google Maps, and Wireshark applications. OpenSignal was employed to identify the locations of Base Transceiver Station (BTS) towers, Google Maps was used to determine the distance between users and BTS locations, and Wireshark was utilized to measure QoS parameters, namely throughput, packet loss, delay, and jitter. The research adopted an action research approach consisting of planning, implementation, and evaluation stages based on QoS analysis. The results indicate significant variations in QoS among the three providers. These differences are primarily influenced by signal attenuation due to variations in user distance from BTS towers and by network congestion caused by high user density in specific locations.
