Abstract

Software-Defined Networking (SDN) offers revolutionary flexibility and centralized management, yet ensuring reliable Quality of Service (QoS) for various applications remains a primary challenge. Although extensive research on QoS in SDN has been published, the proposed architectures, methods, and evaluation metrics are often disparate and complex. Consequently, A discernible gap exists in the current literature regarding a comprehensive survey of the research landscape for QoS in SDN. This literature review aims to identify and analyze the research trends, architectures, methods, and metrics related to QoS in SDN published between 2020 and 2025. Based on inclusion and exclusion criteria, 80 studies on QoS in SDN were identified. The analysis reveals four main research topics: Resource Management (45%), QoS-aware Routing (30%), Traffic Classification (20%), and QoS Security (5%). The majority of studies (70%) utilize simulation environments such as Mininet, while 30% employ physical testbeds In terms of methodology, it was found that mathematical optimization approaches such as Mixed-Integer Linear Programming (MILP) are still the most frequently implemented. However, there is a very clear trend of increasing proposals for Machine Learning (ML)-based methods, particularly Reinforcement Learning, as a solution for dynamic QoS management. This review provides a holistic view for researchers and practitioners to understand the current state and future direction of QoS research in SDN environments.

Abstract

Kasus pelecehan seksual berbasis daring pada layanan media sosial X menimbulkan tantangan dalam praktik forensik digital, terutama ketika pelaku menghapus pesan sehingga artefak komunikasi tidak lagi terlihat pada aplikasi. Permasalahan ini menyulitkan proses pembuktian dan menuntut investigasi yang sistematis serta dapat dipertanggungjawabkan secara hukum. Penelitian ini bertujuan menganalisis proses pemulihan barang bukti digital pada kasus pelecehan seksual daring menggunakan metode Association of Chief Police Officers (ACPO). Metode ACPO diterapkan melalui tahapan Plan, Capture, Analyze, dan Present dengan memanfaatkan dua tools forensik, yaitu MOBILedit Forensic Express dan Magnet AXIOM. Objek analisis berupa artefak Direct Message yang meliputi 17 pesan teks, 2 gambar, 2 video, 1 pesan suara, dan 2 informasi akun. Hasil penelitian menunjukkan bahwa MOBILedit Forensic Express berhasil memulihkan seluruh artefak gambar, video, dan informasi akun, namun hanya sebagian pesan teks dan tidak memulihkan pesan suara. Sementara itu, Magnet AXIOM berhasil memulihkan gambar, video, dan pesan suara secara lengkap, tetapi memiliki keterbatasan dalam pemulihan pesan teks dan informasi akun. Secara kumulatif, kombinasi kedua tools menghasilkan pemulihan penuh pada artefak multimedia dan akun, sedangkan pesan teks hanya mencapai 58,52%. Temuan ini menegaskan bahwa penggunaan lebih dari satu tools forensik dalam kerangka metode ACPO dapat meningkatkan efektivitas pengumpulan barang bukti digital pada investigasi pelecehan seksual di media sosial.
