A Live Demonstration of HiPerConTracer 2.0
In Proceedings of the 31st International Conference on Software, Telecommunications and Computer Networks (SoftCOM). Split/Croatia, 2023.Status: Accepted
A Live Demonstration of HiPerConTracer 2.0
HiPerConTracer is an open source tool for large-scale, long-term, high-frequency Ping and Traceroute measurements. Using such measurements, it is possible to obtain information about latency in the network, as well as about the actual routing. This proposed live demo provides an overview over the tool and its features, as well as an introduction of how to use it for performing measurements, storing the results, querying selected results, and post-processing them for visualisation.

Detecting Physical Impacts by Monitoring State of Polarisation in a Live Fibre-To-The-Home Data-Communication Air-Cable
Heavy wind may tear cables down, damaging infrastructure, triggering outage in data-communication networks. We demonstrate local observations of wind in the access-network, monitoring State of Polarisation in a live Fiber-To-The-Home air-cable.

Evolved Cold-Potato routing experiences
In The 31st International Conference on Software, Telecommunications and Computer Networks (SoftCOM 2023) . Split, Croatia: IEEE, 2023.Status: Accepted
Evolved Cold-Potato routing experiences
This paper presents a system designed to enhance Quality of Service (QoS) for a global video conferencing service. By a combination of off-the-shelf equipment and open-source software, the proposed system establishes a global service net- work with efficient cold-potato internal routing techniques.
Through 15 years of operational experience, we have developed egress selection heuristics to minimize latency and loss in real- time, end-to-end services. The use of legacy routers and switches guarantees stability and security, while the implementation of specially adapted Route Reflector software provides flexibility.
This study highlights the notable enhancements achieved in terms of accurate egress routing placement, latency reduction, and a significant decrease in customer support cases. By sharing our experiences, we aim to contribute valuable insights to the field of network optimization for real-time services.

How Large Is the Gap? Exploring MANRS and ISO27001 Security Management
In The 31st International Conference on Software, Telecommunications and Computer Networks (SoftCOM 2023) . Split, Croatia: IEEE, 2023.Status: Accepted
How Large Is the Gap? Exploring MANRS and ISO27001 Security Management
Ensuring security of network traffic between op- erators is very important. This paper aims to enhance un- derstanding of the relationship between two crucial internet security standards, namely, Mutual Agreed Norms for Rout- ing Security (MANRS) and ISO/IEC 27001 (ISO27001). By examining the correlation between MANRS participation and ISO27001 certification, this study provides insightful analysis. To validate compliance, data from diverse sources such as CAIDA, PeeringDB, and RPKI is correlated. We assess ISO27001 controls that bear relevance to MANRS compliance and illustrate how implementing either framework leads to a reduced risk of security breaches. Moreover, a cost analysis reveals that the simultaneous implementation of MANRS and ISO27001 does not significantly increase costs or complexity.

Live Streaming Technology and Online Child Sexual Exploitation and Abuse - A Scoping Review
Trauma, Violence, & Abuse (2023).Status: Accepted
Live Streaming Technology and Online Child Sexual Exploitation and Abuse - A Scoping Review
Livestreaming of child sexual abuse is an established form of online child sexual exploitation
and abuse. However, only a limited body of research has examined this issue. The Covid-19
pandemic has accelerated internet use and user knowledge of livestreaming services
emphasising the importance of understanding this crime. In this scoping review, existing
literature was brought together through an iterative search of eight databases containing peer-
reviewed journal articles, as well as grey literature. Records were eligible for inclusion if the
primary focus was on livestream technology and online child sexual exploitation and abuse,
the child being defined as eighteen years or younger. Fourteen of the 2,218 records were
selected. The data were charted and divided into four categories: victims, offenders,
legislation, and technology. Limited research, differences in terminology, study design, and
population inclusion criteria present a challenge to drawing general conclusions on the
current state of livestreaming of child sexual abuse. The records show that victims are
predominantly female. The average livestream offender was found to be older than the
average online child sexual abuse offender. Therefore, it is unclear whether the findings are
representative of the global population of livestream offenders. Furthermore, there appears to
be a gap in what the records show on platforms and payment services used and current digital
trends. The lack of a legal definition and privacy considerations pose a challenge to
investigation, detection, and prosecution. The available data allow some insights into a
potentially much larger issue.

Energy Efficient AoI Minimization in Opportunistic NOMA/OMA Broadcast Wireless Networks
IEEE Transactions on Green Communications and Networking (2021).Status: Accepted
Energy Efficient AoI Minimization in Opportunistic NOMA/OMA Broadcast Wireless Networks
The concept of Age of Information (AoI) minimization in wireless networks has garnered huge interest in recent times. While current literature focuses on scheduling for AoI minimization, there is also a need to efficiently utilize the underlying physical layer resources. In this paper, we consider the problem of energy-efficient scheduling for AoI minimization in an opportunistic NOMA/OMA downlink broadcast wireless network, where the user equipment operate with diverse QoS requirements. We first formulate a resource allocation problem to minimize the average AoI of the network, with energy-efficiency factored in by restricting the long term average transmit power to a predetermined threshold. A heuristic adaptation of the driftplus-penalty approach from the Lyapunov framework is then utilized to solve the original long-term mixed-integer nonlinear problem on a per time-slot basis. The single time-slot problem is further decomposed into multiple sub-problems, solving for power allocation and user scheduling separately. However, the attained power allocation sub-problems being non-convex, we propose an efficient piece-wise linear approximation to obtain a tractable solution. The scheduling sub-problem is solved optimally by using the integrality property of the linear program. Finally, we provide extensive numerical simulations to show that our proposed approach outperforms the state of the art.
