With the increasing number of end users that are using multimedia services, demand for access network high bitrate systems with sufficient quality of services also increases. However, this might not always be ensured by the telecom operators, as they must perform network optimization concerning Quality of Service (QoS) and multimedia data transmission. In this work, we focused on Gigabit Passive Optical Network (GPON) performance testing with the help of various tools (iPerf, RFC 6349 or ITU-T Y.1564). The Grafana software tool is used to monitor data streams. Measurements were made to limit the downstream bitrate of up to 20 end users at 100 Mbit/s. Based on the repeated measurements, an aggregation curve is modelled indicating the available bitrate with respect to the network load. © 2025 SPIE.

Datasets of labeled network traces are essential for a multitude of machine learning (ML) tasks in networking, yet their availability is hindered by privacy and maintenance concerns, such as data staleness. To overcome this limitation, synthetic network traces can often augment existing datasets. Unfortunately, current synthetic trace generation methods, which typically produce only aggregated flow statistics or a few selected packet attributes, do not always suffice, especially when model training relies on having features that are only available from packet traces. This shortfall manifests in both insufficient statistical resemblance to real traces and suboptimal performance on ML tasks when employed for data augmentation. In this paper, we apply diffusion models to generate high-resolution synthetic network traffic traces. We present NetDiffusion, a tool that uses a finely-Tuned, controlled variant of a Stable Diffusion model to generate synthetic network traffic that is high fidelity and conforms to protocol specifications. Our evaluation demonstrates that packet captures generated from NetDiffusion can achieve higher statistical similarity to real data and improved ML model performance than current state-of-The-Art approaches (e.g., GAN-based approaches). Furthermore, our synthetic traces are compatible with common network analysis tools and support a myriad of network tasks, suggesting that NetDiffusion can serve a broader spectrum of network analysis and testing tasks, extending beyond ML-centric applications. © 2024 Copyright held by the owner/author(s).

This paper focuses on analyzing the connectivity of Xiaomi IoT devices to the cloud to propose solutions to identified problems in the case of DNS server failure. The connectivity analysis of the IoT devices was performed in a test environment that included different scenarios such as adding IoT devices to the application, the functionality of the IoT device, the automation of the IoT device and the voice assistant for the IoT devices. The testing scenarios were performed with a functional network and a simulation of a DNS server outage. Based on the identified problems in the communication between IoT devices and the cloud, solutions were proposed to ensure reliable communication between IoT devices and the cloud without depending on the DNS server. In this paper, solutions are proposed that can help improve the stability and reliability of the IoT when using DNS services. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Modern data centers deploy disaggregated storage systems (e.g., NVMe over Fabrics, NVMe-oF) for fine-grained resource elasticity and high resource utilization. A client-side writeback cache is used to absorb writes and buffer frequently accessed data, thereby eliminating unnecessary remote storage accesses and improving performance. Yet, a cache miss on the full cache triggers an evict-and-fetch operation which evicts the old entries before new data blocks are fetched. Existing systems perform the evict-and-fetch operation by sequentially executing write and read I/O operations, which reduces the concurrency and makes it challenging to fully utilize the fast network and storage devices. To overcome this problem, we propose Volley, a network storage protocol that guarantees the execution order of the write and read I/O operations, enabling the writeback cache to issue eviction and fetch operations simultaneously. We implement the Volley protocol by extending NVMe-oF atop commodity network and storage hardware and further the ACK free-rides and notification acceleration techniques to reduce the network overhead. We adopt Volley into two writeback caching systems (V-Cache and V-TriCache) for virtual machine storage and out-of-core computing, respectively. Evaluations show that V-Cache outperforms Linux page cache and SPDK OCF (a state-of-the-art caching system) by up to 6.84× and 3.01×. Experiments on a production workload of Facebook (Mixgraph) show that V-TriCache reduces the total running time by up to 16.7% compared with the state-of-the-art out-of-core computing system, TriCache. © 2024 Owner/Author.

Computer networking is understanding a network of connected computers that may communicate and share resources, by following a set of principles referred to as communications protocols. The internet Protocol (IP) lies in the network layer protocol that forms a part of the internet protocol suite, enabling the transmission of data packets across different network boundaries. To join a network, a device requires an IPv6 address, which must be different and unique. The DAD process is a helpful method for finding duplicate addresses in a network. When a machine enters the network, it must generate a distinct IPv6 address to connect with other nodes Before assigning an IPv6 home address to the physical interface, Duplicate address detection (DAD), an essential technique, assures that it is the only IPv6 home address on the local-area-network (LAN). This paper digs into significance of DAD, its potential vulnerabilities, and various solutions proposed by the authors. Additionally, this paper provides several literary perspectives and recommends potential areas for future research on DAD. © 2025 IEEE.

Comparing Sensitivities of Geodetic Processing Methods for Rapid Earthquake Magnitude Estimation

Rapid earthquake magnitude estimation from real-time space-based geodetic observation streams provides an opportunity to mitigate the impact of large and potentially damaging earthquakes by issuing low-latency warnings prior to any significant and destructive shaking. Geodetic contributions to earthquake characterization and rapid magnitude estimation have evolved in the last 20 yr, from post-processed seismic waveforms to, more recently, improved capacity of regional geodetic networks enabled real-time Global Navigation Satellite System seismology using precise point positioning (PPP) displacement estimates. In addition, empirical scaling laws relating earthquake magnitude to peak ground displacement (PGD) at a given hypocentral distance have proven effective in rapid earthquake magnitude estimation, with an emphasis on performance in earthquakes larger than similar to M-w 6.5 in which near-field seismometers generally saturate. Although the primary geodetic contributions to date in earthquake early warning have focused on the use of 3D position estimates and displacements, concurrent efforts in time-differenced carrier phase (TDCP)-derived velocity estimates also have demonstrated that this methodology has utility, including similarly derived empirical scaling relationships. This study builds upon previous efforts in quantifying the ambient noise of three-component ground-displacement and ground-velocity estimates. We relate these noise thresholds to expected signals based on published scaling laws. Finally, we compare the performance of PPP-derived PGD to TDCP-derived peak ground velocity (PGV), given several rich event datasets. Our results indicate that TDCP-PGV is more likely than PPP-PGD to detect intermediate magnitude (similar to M-w 5.0-6.0) earthquakes, albeit with greater magnitude estimate uncertainty and across smaller epicentral distances. We conclude that the computationally lightweight TDCP-derived PGV magnitude estimation is complementary to PPP-de

The new cloud-network operation system is based on cloud, distributed technology and service-oriented architecture, aiming to improve the operation efficiency of cloud-network through all-digital transformation. Unified service modelling is a prerequisite for the construction of the new cloud-network operation system. This paper proposes a PSR (Product, Service, Resource) layered decoupling model and encapsulates standardized network capabilities across the network based on the PSR model in order to realize the intelligent opening and operation of the cloud-network. By introducing China Telecom's PSR model and proposing the basic principles and design methods of IP network capabilities encapsulation design under the PSR model architecture, as well as sharing the practical cases and exploratory experiences of IP network capabilities design and capabilities opening, this paper lays a solid technical foundation for the enterprise's digital transformation and the construction of intelligent, automated, and visualized operation and service system. © 2025 SPIE.

With the continuous advancement of in-vehicle network technology, Controller Area Network (CAN) technology has become a key component of automotive control systems. As a standardized automotive diagnostic communication protocol, the Unified Diagnostic Services (UDS) protocol plays a crucial role in fault detection and vehicle maintenance. As the complexity of in-vehicle network systems increases, communication faults between Electronic Control Units occur frequently. In response to this issue, a diagnostic strategy based on the UDS protocol has been developed. This strategy can effectively differentiate communication interruptions caused by external interference from those caused by internal faults, enabling precise diagnosis of internal faults in in-vehicle network systems and significantly improving the accuracy of fault detection. © 2025 SPIE.

With the advancement of Software-Defined Networking (SDN) technology, network programmability and flexibility have been significantly enhanced. However, effectively integrating traditional network systems with emerging programmable platforms remains a critical research challenge. This paper proposes a fusion architecture based on the P4Runtime protocol to achieve deep integration of SONiC white box switches and the P4 platform. By introducing SDN programmability, we design and implement a hybrid model that enables traditional network architectures to achieve advanced functionalities with the assistance of external SDN controllers. This paper provides a detailed discussion of the architecture design and implementation process, including P4 code development, compilation, target configuration file generation, and interaction mechanisms between the control plane and the data plane. Furthermore, we validate the applicability and performance of the architecture in various scenarios, offering robust support for future research and applications in programmable networks. © 2025 IEEE.
