This white paper discusses the evolution from circuit-switched to packet-based core networks. It notes that most modern communications, including voice calls, video, and file transfers, are delivered via packets. However, some core networks have not fully converged on packet transport, still relying on legacy circuit-switched infrastructure that is more costly and complex. The paper examines different transport technologies and argues that a fully packet-based approach using next-generation packet switches can optimize costs while improving scalability, manageability and bandwidth utilization compared to hybrid circuit-packet networks.
T Series Core Router Architecture Review (Whitepaper)Juniper Networks
Juniper Networks® T Series Core Routers have been in production since 2002, with the introduction of the Juniper Networks T640 Core Router. Since that time, T Series routers have evolved to maintain an unequivocal industry lead in capacity (slot, chassis, and system) and operational efficiencies in power and usability. Maintaining this standard has in part been possible due to design decisions made with the very first T Series system. The T Series demonstrates how Juniper has evolved its router architecture to achieve substantial technology breakthroughs in packet forwarding performance, bandwidth density, IP service delivery, and system reliability. At the same time, the integrity of the original design has made these breakthroughs possible. Not only do T Series platforms deliver industry-leading scalability, they do so while maintaining feature and software continuity across all routing platforms. Whether deploying a single-chassis or multichassis system, service providers can be assured that the T Series satisfies all networking requirements.

Automated clock mesh analysis for faster turnaroundAnimesh Sharma
This document describes an automated clock mesh analysis (CMA) flow that uses SPICE simulation within a static timing analysis (STA) tool to model clock mesh networks. The CMA flow extracts the clock mesh network, runs SPICE simulation on it, and back-annotates delays and slews to the STA tool. This allows clock meshes to be analyzed faster and more accurately compared to traditional manual SPICE simulations or STA tools alone. Experimental results show the CMA flow matches an internal simulator to within 1.365% for cell delays and transitions, while reducing analysis time from a week to less than an hour.

It is comprised of two modules, the first covering basic routing concepts like route tables, interface types, routing protocols RIP and OSPF, and route redistribution. The second module dives deeper into OSPF, explaining concepts like adjacency, areas, LSAs, SPF calculation, and how routing updates are exchanged. The document also includes an agenda laying out the topics to be covered in the course.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
