Networks are moving toward simplification, increased operational efficiency, and programmability using technologies such as software-defined networking. Cisco continues to demonstrate innovation by introducing the concept of segment routing in the data center, making the network more intelligent and adaptive to the applications running on top of it. Segment routing delivers application-optimized network transport. Encoding the path information directly at the source (that is, either at the virtual switch or at the top of rack) and using per-app policies, segment routing puts control in the hands of the network operators by empowering them to create secure, adaptive, and optimal paths based on the requirements of the application itself.
Please join us in the session to learn how Cisco is helping organizations increase network efficiency by allocating resources on demand and optimizing the network to better support business-critical applications, all while preserving security.
Agenda
Topics to discuss include:
- Introducing segment routing
- Why the need for application-optimized transport
- Features and benefits of segment routing
- Differences between segment routing and MPLS transport
- Relevance of segment routing in the data center
- Use cases and applicability of segment routing
- Summary and conclusion

c-quilibrium R forecasting integration
This document discusses the integration of an improved forecasting algorithm developed using R into c-Quilibrium's cash supply chain optimization solution. A proof-of-concept using R was successful and outperformed the previous Visual Basic algorithm. The operationalization required considerations for scalability, maintaining a single codebase for analysis and production, code protection, logging, exception handling, and providing an analysis GUI. Solutions like using foreach for parallelization in R, embedding and obfuscating R code in .NET, and connecting multiple RServe processes were proposed to meet integration and non-functional requirements.
Link_NwkingforDevOps
The document discusses how application architects traditionally focused on solving IO bottlenecks in servers by offloading processing to intelligent network interface cards. With modern distributed applications spanning thousands of servers, application architects now must consider network topology, segmentation, and control plane protocols to optimize latency and bandwidth. The rise of virtualization and cloud computing has changed traffic patterns in datacenters from north-south traffic to dominant east-west traffic between servers. This requires new datacenter fabric designs beyond the traditional three-tiered topology.
RINA research results - NGP forum - SDN World Congress 2017
RINA is a radically simple network architecture that takes an inter-process communication (IPC) approach. The key aspects of RINA are:
1) It uses a single type of layer called a Distributed IPC Facility (DIF) that can repeat as many times as needed. Each layer provides the same service of communication flows between application instances.
2) Layers isolate different scopes and allocate resources (e.g. bandwidth) to competing flows in a programmable way.
3) Experimental results show RINA can solve problems like congestion control and seamless renumbering more easily than IP networks. It also simplifies network management.

Network Support for Cloud Applications - Felix Cuadrado
The document discusses network support for cloud applications. It notes that cloud applications span multiple datacenters and content delivery networks, and have requirements around user latency and reliability. It proposes using software-defined networking (SDN) to give applications more programmatic control over the network and help optimize placement and migration decisions. SDN could provide network monitoring data and help orchestrate both computing and network resources to meet applications' quality of service needs in a dynamic cloud environment.
Rina converged network operator - etsi workshop
1. The document discusses a converged network vision that supports any access media and application using a common network infrastructure with a single architecture, management system, and user database.
2. It questions whether all-IP networks are fit for this purpose, as the IP protocol suite was not designed for generality and scalability.
3. The document introduces RINA as a better approach, describing its unified model of networking as inter-process communication, consistent layered architecture, and support for naming, addressing, mobility, security, and management.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Embedded machine learning-based road conditions and driving behavior monitoring
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.
