Abstract

This research aims to evaluate the performance of a Hyperledger Fabric-based blockchain system implemented for digital diploma management. The system is tested using the Caliper benchmark tool in various network and scalability scenarios, including normal conditions (baseline), network delay of 50ms, 100ms, 200ms, and 500ms; packet loss of 1%, 5%, 10%, and 15%; bandwidth limitation of 5 Mbps; high transaction load (scalability standard and scalability optimized); and extreme conditions in the form of Byzantine attacks with malicious nodes of 10%, 30%, and 50%. The evaluation was conducted using four key metrics: transaction success rate, failure rate, average transaction latency, and throughput (TPS). The system recorded high performance under normal network conditions with a success rate of 99.8%, latency of 0.89 seconds, and throughput of 9.7 TPS. Network disruptions such as delay, packet loss, and bandwidth limitation had only a minor impact, with the success rate remaining above 99% and latency gradually increasing. High load in the scalability scenario caused latency to increase to 27.21 seconds and failure rate to rise, but improved significantly after chaincode optimization. Meanwhile, the Byzantine scenario showed a drastic drop in performance with the success rate decreasing to 12.83% and the failure rate increasing to 87.17%. These results show that the Hyperledger Fabric-based digital diploma management system is resilient to common network disruptions and reliable at medium scale, but still requires strengthening the consensus mechanism to deal with extreme conditions and maintain reliability in environments that are not fully trusted.

Abstract

Container-based virtualization telah diterima di seluruh Platform Cloud dalam beberapa tahun terakhir, dan tren ini kemungkinan akan berlanjut di tahun-tahun mendatang. Akibatnya, sistem container orchestration menjadi semakin penting. Karena stability, maturity, dan fungsionalitasnya yang komprehensif, Kubernetes telah menjadi standar de facto. Semua penyedia Cloud utama pada saat ini menawarkan solusi Kubernetes terkelola Cloud-Native untuk membebaskan pengguna dari tekanan karena harus merancang dan memelihara infrastruktur Kubernetes yang rumit sambil tetap memanfaatkan fungsinya. Sebagai contoh pada tahun 2022, sebanyak 96% dari Sysdig’s global customer yang menggunakan layanan container memilih Kubernetes sebagai Container Orchestration-nya. Dan dalam laporan awal CNCF pada tahun 2022 sebanyak 79% responden menggunakan layanan terkelola seperti Google Kubernetes Engine (GKE). Tujuan artikel ini adalah untuk menganalisis performa container yang berjalan secara hosted seperti pada Google Cloud Platform (GCP). Analisis dilakukan dengan cara pengujian secara real-time yang dilakukan didalam cluster Kubernetes, yang terdiri dari dua node dengan instance mesin 4vcpu yang dideploy dengan nginx:1.23. Execution time dilakukan sebanyak 50.000 eksekusi, menghasilkan waktu terbaik 0,0000106 sec per loop. Total pengunaan memori adalah 18,36 MiB, dengan network received sebesar 16,015 KiB/s dan network transmitted sebesar 16,057 KiB/s. Adapun value price performance yang didapatkan Google Cloud Platform (GCP) yaitu sebesar 952,4 MIPS/$.

Abstract

5G Core (5GC) Network merupakan salah satu teknologi utama pada teknologi seluler generasi ke-5. Perubahan besar yang terjadi pada 5GC adalah perubahan dari arsitektur monolithic menjadi arsitektur yang modular dan aksesnya dibuka untuk umum. Hal ini merubah pengembangan 5GC menjadi lebih baik. Beberapa penelitian yang sudah dilakukan masih menggunakan 5GC non-standalone yang ditandai dengan hadirnya Evolved Packet Core (EPC) dalam implementasinya. Maka dari itu penelitian ini bertujuan untuk mengimplementasikan arsitektur 5GC standalone yang didefinisikan oleh 3GPP release 15 pada baremetal server. Kemudian 5GC diintegrasikan dengan User Equipment (UE) dan Radio Access Network (RAN). Percobaan ini menggunakan metode penelitian yang mencakup instalasi dan konfigurasi source code Free5GC, integrasi dengan simulator UERANSIM, serta pengujian performa menggunakan metrik bandwidth, throughput, dan round-trip time (RTT). Setelah dilakukan pengukuran performa menggunakan beberapa metrik pengukuran dari 5GC yang telah dibangun dapat disimpulkan bahwa 5GC yang dibangun berhasil diimplementasikan dan berfungsi dengan baik dalam mendukung konektivitas data. Pengujian performa mencatat bandwidth rata-rata sebesar 3,5 Gbps, throughput rata-rata 21,04 Mbps untuk unduh dan 19,125 Mbps untuk unggah, serta RTT rata-rata 21,229 ms. Penelitian ini memberikan kontribusi penting dalam pengembangan jaringan 5G yang terbuka dan dapat diandalkan, terutama pada aspek konektivitas data. 5G Core (5GC) Network is a key technology in fifth-generation cellular systems. One of the significant advancements in 5GC is the shift from a monolithic to a modular architecture with open access, enabling better development of the technology. However, many existing studies still focus on non-standalone 5GC, which includes the Evolved Packet Core (EPC) in its implementation. This study aims to implement a standalone 5GC architecture, as defined by 3GPP Release 15, on a bare metal server. The implementation integrates 5GC with User Equipment (UE) and Radio Access Network (RAN). The research methodology involves installing and configuring the Free5GC source code, integrating it with the UERANSIM simulator, and evaluating its performance using metrics such as bandwidth, throughput, and round-trip time (RTT). Results show that the implemented 5GC operates successfully and effectively supports data connectivity. The performance tests recorded an average bandwidth of 3.5 Gbps, a download throughput of 21.04 Mbps, an upload throughput of 19.125 Mbps, and an average RTT of 21.229 ms. This study contributes significantly to the advancement of open, flexible, and reliable 5G networks, particularly in enhancing data connectivity performance.

Abstract

Nowadays, world wide telecommunication researchers are developing 5G technology. One of most important key technology in 5G is Milimeter-Wave (mmWave). This study measure 60 GHz broadband wireless system performance because of it’s promising potentials. However, the use of these frequencies is quite sensitive to rain that resulting an atenuation in the channel. Therefore, this study proposes two schemes to address the problem. The first scheme is the use of QAM modulation (Quadrature Amplitude Modulation) and the second scheme is an addition of LDPC (Low Density Parity Check) code techniques. From the results of this study, by using 4-QAM modulation and LDPC coderate 1/2, the broadband wireless system’s performance on the second scheme is better compared to the first scheme with 8.33 dB Signal to Noise Ratio (SNR) value to provides BER (Bit Error Rate) 10-4
