Recently, large language models (LLMs) have emerged as a promising AI technology with the potential to revolutionize network management and operations through natural language interaction. In this paper, we provide a comprehensive survey of LLM-based approaches in network management and compare those approaches with existing methods. We identify key advantages of LLM-based approaches, such as their ability to interpret intent and automate complex tasks, as well as limitations, which include hallucinations and domain adaptation challenges.

The most critical user data packet handler in the 5GC network function (NF) is the user plane function (UPF), which is responsible for moving data from the user equipment to the destination data network, and vice versa. Existing work mainly focuses on implementing UPF using the key technologies of high-speed data processing. In this paper, with a mobile core provider called free5GC for a stand-alone (SA) 5G network, we share our experience with the implementation of UPF by using a programmable hardware appliance, which can offer more Tbps compared with the implementation of software UPF that can offer only a few hundred Gbps. For that, we demonstrate how to build up a more flexible architecture of UPF by using the software-defined networking (SDN) concept due to the opacity of protocol specification. We split the UPF control signal implementation into a software application and user data packet processing into a programmable hardware appliance. We also show how to integrate a number of current UPF data plane free5GC implementations, such as Data Plane Development Kit (DPDK), Linux kernel module, and SmartNIC. Furthermore, we analyze and make use of microservices to support the specific features of the UPF data plane that cannot be implemented in a programmable hardware appliance. We tested our free5GC mobile network and the new UPF design architecture that can run on a real programmable hardware appliance from Accton CSP-7551.

Since then, the exponential increase in the price of some of these digital artworks has made them inaccessible to many small investors and private collectors. For this reason, various protocols such as Fractional.art have emerged to democratize the process, allowing users to fractionalize NFTs to make trading more fluid. The objective of this article is to analyze the NFTs fractionated into ERC-20 tokens using the Fractional.art protocol, with the aim of determining the contribution of fractionation to the liquidity of the assets, among others. The research method employed is an empirical analysis based on quantitative research to identify key characteristics and trends to support the initial hypothesis. This is combined with a qualitative approach to provide a deeper understanding. The results show that fragmentation has a positive effect on the liquidity of the NFT when the user decides to trade it. This means that fractionated NFTs can benefit from certain liquidity advantages of centralized investment markets, thereby facilitating trading. While NFTs have received increasing scholarly attention, most research on fractionalized NFTs has focused on the theoretical and technical design of fractionation protocols. Although recent studies have begun to empirically examine NFT market dynamics more broadly, there remains limited evidence on whether fractionalization effectively enhances liquidity. This article seeks to contribute to that emerging area by offering a focused, data-driven analysis of F-NFT liquidity and user behavior.</p>","PeriodicalId":14154,"journal":{"name":"International Journal of Network Management","volume":"35 6","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/nem.70027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these challenges, researchers have developed various address discovery methods aimed at maximizing the identification of active IPv6 addresses within constrained resource budgets. This paper summarizes and analyzes existing active address discovery methods and evaluates their performance in real-world environments. Our work includes classifying detection techniques and outlining the current research landscape for address discovery in regions without seed addresses. Through experiments conducted in real network environments, we evaluate and contrast different probing algorithms using four performance metrics: hit rate, hierarchical prefix coverage, aliased addresses, and address discovery rate.

Both underloading and overloading can cause system inefficiencies, including increased power consumption, prolonged execution times, and higher machine failure rates. Therefore, effective load balancing (LB) becomes a critical aspect of task scheduling in cloud systems, whether at the level of virtual machines (VMs) or independently. To address these challenges, this paper proposes the Chronological Kookaburra Optimization Algorithm (ChKOA) for efficient LB in cloud computing (CC). The proposed ChKOA is the combination of chronological concept with the Kookaburra Optimization Algorithm (KOA). Initially, tasks are assigned to VMs in a round-robin manner. Based on specific VM parameters, the VMs are classified into overloaded and underloaded categories using deep embedded clustering (DEC). Tasks in overloaded VMs are prioritized and redistributed to underloaded VMs, considering factors such as supply, demand, capacity, predicted load, and key Quality of Service (QoS) metrics, including resource availability and reliability. Load prediction is performed using a Deep Residual Network (DRN). Simulation results demonstrate that the proposed ChKOA achieves a balanced load of 0.535, capacity utilization of 0.954, resource availability of 0.954, reliability of 0.936, and a computational cost of 0.327 s.</p>\u0000 </div>","PeriodicalId":14154,"journal":{"name":"International Journal of Network Management","volume":"35 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144725705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current connection migration is passive, designed to support mobile handover and weak network environments. In this paper, we propose proactive connection migration for QUIC (PCM-QUIC), which combines connection migration and online path selection, enabling QUIC to select the best quality transmission path while maintaining the connection. First, PCM-QUIC integrates the exploration of network quality across different paths into multiple user request actions. Then, considering response completion time and jitter, PCM-QUIC identifies the optimal access path for the current Internet service through online learning. In addition, we propose an upper confidence bound-based path selection algorithm with the goal of minimizing the confidence upper limit of the path reward.

Unlike traditional methods like ECMP and WCMP, MTS-PolKA dynamically adjusts traffic division using source-routing labels embedded in packet headers—without requiring reconfiguration of network switches.

Using the Service Weaver framework and deploying the Online Boutique app on Amazon EKS, the study reveals that finer granularity improves scalability but increases communication overhead, while cloud-native resilience features mitigate failures at the cost of performance, especially in tightly coupled configurations. Our findings emphasize the need to strike a careful balance between service granularity, performance, and resilience to build robust and efficient cloud-based microservice applications.&lt;/p&gt;&lt;p&gt;In the third contribution, entitled “Beyond Size: Investigating the Impact of Scaled-Down Network Telescopes on Threat Detection,” Camargo et al. examine how reducing IPv4 address space affects the effectiveness of network telescopes used in cyber threat intelligence.
