This document discusses approaches for providing quality of service (QoS) on the Internet. It describes two main service types: Integrated Services (IntServ) which uses resource reservation on a per-flow basis, and Differentiated Services (DiffServ) which prioritizes aggregates of traffic based on packet markings. While IntServ allows for strict QoS guarantees through signaling and per-flow state, it does not scale well. DiffServ aims to provide QoS for traffic classes through simple packet classification and queuing at network edges and core routers, avoiding per-flow state for better scalability. The document also covers challenges with end-to-end QoS and outlines components needed for a DiffServ architecture.

Policy control in epc
Policy control is a process that defines and enforces business rules to enable services like quality of service guarantees, usage quotas, and traffic optimization. In telecom networks, the Policy Charging and Rules Function (PCRF) plays a key role in policy control. It interfaces with gateways to make policy decisions that enforce business rules for charging and authorized network usage on a per-subscriber and per-application session basis. As networks evolve from 2G/3G to 4G/LTE architectures using the Evolved Packet Core, policy control becomes more dynamic and essential to support new services, applications and business models.
Policy control and charging for lte
This document discusses the three phases of LTE network deployment:
Phase 1 focuses on LTE for data only services using USB modems. Phase 2 introduces LTE handsets but relies on circuit switched fallback for voice. Phase 3 transitions to a full IP LTE/IMS environment for integrated voice, messaging, and data services. However, replacing existing circuit switched infrastructure with IMS will be a long-term goal due to significant costs and time required for such a transition. Operators will take an incremental approach, initially focusing on policy and charging platforms that can work with both legacy and new systems.

Content Delivery Networks are the key for today’s internet content delivery. Users are knowingly or unknowingly accessing the CDN via internet. No matter how much the data retrieved by the user it may contain the CDN hand behind every character of text and every pixel of image. CDN came into existence to solve the delay problem. The moment when a user requests for a web page and the response delivered to the corresponding users web browser facing a huge delay. The main goal of this paper is content distribution of web services to multiple data centers placed in different geographical locations and providing security. A content distribution service is a major part of popular Internet applications. In proposed system hybrid clouds are used i.e., both private cloud as well as public cloud. One data center is allocated to each region. Providing security to the data is always an important issue because of the critical nature of the cloud and very large amount of complicated data it carries. To provide security cipher text policy algorithm is used. Authentication technique is used to verify the user authentication. If the user is authorized to access services then and only he receives configuration key to use.

CDN
A content delivery network (CDN) distributes content across multiple servers located in different geographic locations. This improves performance by serving content from the server closest to the user. CDNs provide advantages like decreasing server load, faster content delivery, 100% availability even during outages, increased concurrent users, and more control over asset delivery. While CDNs improve performance, they also have disadvantages to consider like increased complexity and upfront costs.
Content Delivery Network – CDN
A content delivery network or content distribution network (CDN) is a large distributed system of servers deployed in multiple data centers across the Internet. The goal of a CDN is to serve content to end-users with high availability and high performance.

Privacy preserving public auditing for secured cloud storage
As the cloud computing technology develops during the last decade, outsourcing data to cloud service for storage becomes an attractive trend, which benefits in sparing efforts on heavy data maintenance and management. Nevertheless, since the outsourced cloud storage is not fully trustworthy, it raises security concerns on how to realize data deduplication in cloud while achieving integrity auditing. In this work, we study the problem of integrity auditing and secure deduplication on cloud data. Specifically, aiming at achieving both data integrity and deduplication in cloud, we propose two secure systems, namely SecCloud and SecCloud+. SecCloud introduces an auditing entity with a maintenance of a MapReduce cloud, which helps clients generate data tags before uploading as well as audit the integrity of data having been stored in cloud. Compared with previous work, the computation by user in SecCloud is greatly reduced during the file uploading and auditing phases. SecCloud+ is designed motivated by the fact that customers always want to encrypt their data before uploading, and enables integrity auditing and secure deduplication on encrypted data.

- Edge virtualization opens opportunities to host third-party and customer services on the edge through APIs. Examples include regional packet gateways, security services, and CDN expansion. The next steps outlined are to standardize key scenarios and conduct proofs-of-concept.
Cloud Networking Presentation - WAN Summit - Ciaran Roche
This document discusses how multi-cloud networking is impacting enterprises and the role of SD-WAN. It notes that most enterprises now use multiple private, public and hybrid clouds which adds complexity to managing networks and applications. It suggests that the traditional WAN approach does not work well for multi-cloud as the edge becomes more important for directing and prioritizing traffic between cloud environments. SD-WAN is presented as providing an abstraction layer and intelligent edge to effectively manage traffic in multi-cloud networks.
Cloud computing
The document introduces different types of cloud computing services including software as a service, infrastructure as a service, and platform as a service.

International Conference on Telecommunications
This paper proposes a full-duplex device-to-device collaboration scheme for low-latency wireless video distribution in cellular networks. The scheme utilizes cache-enabled user devices and full-duplex radios to bring content closer to users, avoid traffic congestion, and increase throughput and quality of service. The paper analyzes collaboration probabilities, system throughput, and latency for two scenarios: bidirectional full-duplex and three-node full-duplex. Simulation results show improvements in throughput and latency compared to traditional half-duplex systems, with potential for further gains if self-interference is fully canceled.

This document provides an overview and analysis of coding techniques used in 4G LTE-Advanced networks. It describes the core coding steps of randomization, Reed-Solomon encoding, convolutional encoding, interleaving, and modulation. Reed-Solomon coding uses a (255,239) block with 8 bytes of error correction. Convolutional encoding uses a rate 1/2 constraint length 7 code. Interleaving is performed between convolutional and Reed-Solomon encoding to improve performance. Coding blocks are then mapped to the time domain with IFFT and a cyclic prefix is added before transmission over the channel.
Oqpsk
This document discusses offset quadrature phase-shift keying (OQPSK) modulation. It begins by explaining the drawback of traditional quadrature phase-shift keying (QPSK), which is that both the in-phase and quadrature components change simultaneously, resulting in abrupt 180-degree phase changes and large spectral side lobes. It then introduces OQPSK modulation as a modification of QPSK where the quadrature component is offset by one bit period, preventing simultaneous changes in both components and replacing the 180-degree phase jumps with multiple 90-degree phase shifts. This results in better performance for applications using high power amplifiers or satellites. Diagrams are provided to illustrate the difference between the phase transitions of QPSK and O

Adaptive synchronous sliding control for a robot manipulator based on neural ...
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

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.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
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%.

- 3. Introduction A content delivery network or content distribution network(CDN) is a system of caches containing copies of data, placed at various points in a network so as to maximize bandwidth for access to the data from clients throughout the network. Main Goal: A client accesses a copy of the data near to the client, as opposed to all clients accessing the same central server, so as to avoid bottlenecks near that server. Content types include web objects, downloadable objects (media files, software, and documents), applications and real time media streams. Why we need CDNs? What does CDNs stand for?

- 12. CDN Components Delivery Nodes– primary purpose is delivery of data to consumers. It contains caches each running one or more delivery applications; these tend to be deployed as close to the edge (near the consumers) as possible. Storage Nodes – primary purpose is providing data to caches, these can be deployed in a hierarchical model to allow tiered caching and protection to any origin servers. These nodes can also be used where pre-publishing of content is required rather than content being acquired on demand from origin servers. Origin Nodes – these are the master sources for content and can be deployed within the operator’s network (on-net) or more commonly within a content owner’s infrastructure. A number of origins will be provided for scale and resilience. Control Node – primary purpose is to host the management, routing and monitoring components of a CDN. This will be typically the integration point into any OSS/BSS systems and Network Operations Centres.
