Abstract
This paper presents the design and evaluation of a network slicing implementation in a simulated 5G Standalone (SA) mobile network deployed as a nomadic edge node, where “nomadic” refers to the physical portability and ease of redeployment of a self-contained, containerized 5G testbed suitable for university teaching and experimentation. The platform integrates Open5GS, UERANSIM, Kamailio, and Prometheus/Grafana to emulate a sliced 5G core and access network supporting differentiated service requirements typical of heterogeneous traffic classes and latency-sensitive applications. Slice provisioning is fully configurable, and Docker-based resource constraints are applied to enforce Quality of Service (QoS) differentiation. Performance was assessed through bandwidth and traffic-quality measurements, demonstrating measurable improvements in packet loss and jitter for high-priority slices, with corresponding degradation for lower-priority slices. Although the laboratory environment limits replication of distributed real-world deployments, the results confirm the effectiveness of network slicing for traffic isolation and service prioritization in 5G SA systems. These findings highlight the practical boundaries of container-based slicing enforcement in a single-host nomadic 5G SA node, and inform the design of future multi-host deployments.
Network slicing is a key enabling technology for fifth-generation (5G) and beyond mobile networks, which enables operators to run multiple logical networks on top of common physical infrastructure while meeting heterogeneous quality-ofservice (QoS) requirements. In this paper, we summarize the design, implementation, and evaluation of a UDP-based virtual network slicing simulator modeling four slices in accordance with 3GPP service types: enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), Massive Machine-Type Communications (mMTC), and a dedicated Best Effort slice. The simulator uses real UDP sockets on localhost in a multi-threaded framework and implements separate admission control per slice, supporting three configurable resourceborrowing modes—none, full, and controlled—in which the primary slices (eMBB, URLLC, mMTC) may borrow unused capacity from the Best Effort slice when their own allocation runs out. QoS metrics including throughput, packet loss ratio, one-way delay, and jitter are collected in a thread-safe manner per slice. Experimental results under controlled borrowing (60 s, 16 nodes, 3 MB per slice, 40% borrow cap) demonstrate activation of the borrowing mechanism with nonzero borrowed-in and borrowedout values, and illustrate the trade-off between primary-slice throughput and Best Effort protection.

Network Slicing (NS) is a fundamental pillar of 5G and beyond networks, enabling the provisioning of isolated, logical networks tailored to specific Quality of Service (QoS) requirements. While 3GPP standards comprehensively define slicing architectures over cellular access networks, the seamless integration of Non-3GPP technologies such as Wi-Fi into a unified slice instance remains an active area of investigation, particularly regarding empirical validation. This paper presents an end-to-end prototyping study that integrates 5G Standalone (SA) and Wi-Fi networks by adapting the Trusted Non-3GPP Gateway Function (TNGF) to extend NS to WLAN networks, enabling the unified management of Wi-Fi transmission resources. We implement a functional testbed leveraging an open-source 5G Core and an explicit Non-3GPP access to validate multi-Radio Access Technology (multi-RAT) slice operation. Our empirical results showcase the dynamic viability of multi-RAT slicing under varying bandwidth allocations and traffic steering policies, providing a concrete proof of concept for unified 3GPP and Non-3GPP service delivery.

The rapid evolution of beyond-5G and emerging 6G networks is driving the need for flexible, reliable, and cost-efficient virtualized Radio Access Network (vRAN) architectures capable of supporting heterogeneous services such as enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and Massive Machine-Type Communication (mMTC). Future disaggregated RAN systems are expected to rely heavily on network slicing, functional split flexibility, and optical x-haul infrastructures to support stringent performance, scalability, and availability requirements. In this paper, we present an integrated framework for reliable, slice-aware, and functional split-aware Virtual Network Function (VNF) placement with lightpath provisioning in disaggregated vRAN environments. The proposed approach maximizes mobile network operators'profit by jointly optimizing function placement and optical resource allocation under latency, processing, bandwidth, and availability constraints. We formulate the problem as an Integer Linear Programming (ILP) model with two variants: one that employs unshared backups and another that uses a more cost-efficient shared backup scheme. To address ILP complexity, we develop a heuristic algorithm and a Genetic Algorithm (GA)-based metaheuristic that yields near-optimal solutions in real time. Extensive evaluations on topologies up to 128 nodes show that shared backup variants yield up to 18% higher profit, while maintaining up to 5-10% lower normalized CPU usage than unshared counterparts.

Bank Rakyat Indonesia’s conventional network infrastructure based on MPLS is considered to have limitations in traffic management flexibility, bandwidth capacity, and operational cost efficiency. Therefore, the implementation of SD-WAN has emerged as a solution to improve network performance and optimize service quality. This study aims to comparatively analyze the network performance of MPLS and SD-WAN using a quantitative experimental approach in the environment of BRI. The research method was conducted by applying specific treatments and testing scenarios, such as bandwidth configuration, traffic load simulation, and failover testing, followed by controlled measurements of Quality of Service parameters, including throughput, latency, jitter, packet loss, and bandwidth utilization. The research data were obtained from the Dashboard MONICA and Portal NSO. The experimental results indicate that the implementation of SD-WAN improves network performance, particularly in maintaining latency and jitter stability, reducing packet loss, and optimizing bandwidth utilization under various operational conditions. Furthermore, the cost analysis reveals potential operational cost efficiency compared to conventional MPLS-based networks. Based on the experimental results and quantitative analysis, it can be concluded that SD-WAN implementation is technically and economically effective in supporting the modernization of data communication network infrastructure at BRI.
