In this article we provide an overview of pricing concepts for broadband multiservice networks. We review the notions flat pricing, priority Paris-Metro smart-market responsive expected capacity edge and effective bandwidth pricing. use numerous evaluation criteria, including network, economic, social efficiency, as well their suitability in using a means congestion control. Some schemes are based on best-effort networks, thus unable to user with quality service (QoS) guarantees. Others...

With the ever increasing population, urbanization, migration issues, and change in lifestyle, municipal solid waste generation levels are significantly. Hence, management becomes a challenge faced not only by developing nations, but also developed advanced countries. The overall involves three main types of entities: 1) users who generate waste, 2) collectors/city admin., 3) stakeholders. Waste directly effects healthcare, environment, recycling disposal, several other industries. Current...

Internet of Things (IoT) is now transitioning from theory to practice. This means that a lot data will be generated and the management this going big challenge. To transform IoT into reality build upon realistic more useful services, better resource required at perception layer. In regard, Fog computing plays very vital role. With advent Vehicular Ad hoc Networks (VANET) remote healthcare monitoring, quick response time latency minimization are required. However, receiving nodes have...

Network Function Virtualization (NFV) has revolutionized the way network services are offered to end users. Individual functions decoupled from expensive and dedicated middleboxes now provided as software-based virtualized entities called Virtualized Functions (VNFs). NFV is often complemented with Cloud Computing paradigm provide networking enterprise customers end-users remote their premises. along also started be seen in Internet of Things (IoT) platforms a means IoT traffic. The intermix...

The recent advances in vehicular communications and networking are bringing self-driving vehicles closer to reality. Once full automation (i.e., levels 4 5 as defined the five of autonomous driving) becomes a reality, entertainment services for both drivers passengers will shift from listening radios (or music) watching videos. Hence, how improve quality experience (QoE) vehicle (AV) users, reduce network load become crucial problem. Information-centric (ICN) is seen one potential paradigms...

Variable bit rate (VBR) compressed video is expected to become one of the major loading factors in high-speed packet networks such as ATM-based B-ISDN. However, recent measurements based on long empirical traces (complete movies) revealed that VBR traffic possesses self-similar (or fractal) characteristics, meaning dependence stream lasts much longer than traditional models can capture.In this paper, we present a unified approach which, addition accurately modeling marginal distribution...

Lately, pervasive and ubiquitous computing services have been under focus of not only the research community, but developers as well. Different devices generate different types data with frequencies. Emergency, healthcare, latency sensitive require real-time responses. Also, it is necessary to decide what type has be uploaded cloud, without burdening core network cloud. For this purpose, cloud on edge network, known Fog or Micro Datacenter (MDC), plays an important role. resides between...

As devices for the Internet of Things (IoT) are typically battery-powered, energy efficiency is a major challenge IoT networks. In this paper, we leverage in-network caching Information-Centric Networking (ICN) to propose novel cooperative scheme, based on data lifetime and user request rate, improve By at different nodes (such as content routers, base stations, etc.), can stay in sleep mode larger portion time therefore reduce overall consumption. With help an auto- configuration mechanism,...

The research introduced in this paper focuses on controller scalability and performance issues Software-Defined Networks (SDNs), discusses a new routing scheme that leverages variation of Source Routing for use OpenFlow-based networks. aims to reduce the state needed be distributed network devices by controller(s) SDNs, return improve scale, convergence time, fault tolerance cost such architectures.

In this paper we propose an approach for applying traffic load balancing to multicast through real-time link cost modification in a software defined network (SDN) controller. We present SDN controller architecture supporting monitoring, group management, and routing. An implemented prototype is described, used implement shortest path routing techniques which make use of the state flows network. This evaluated experimentation Mininet emulated wide area networks. Evaluation presented terms...

Efficient and fair allocation of multiple types resources is a crucial objective in cloud/distributed computing cluster. Users may have diverse resource needs. Furthermore, diversity server properties/capabilities mean that only subset servers be usable by given user. In platforms with such heterogeneity, we identify important limitations existing multi-resource mechanisms, notably Dominant Resource Fairness its follow-up work. To overcome limitations, propose new server-based approach; each...

Software-Defined Networking has been gaining increasing attention in both the research and industry communities. Separating control data planes brought many advantages such as greater plane programmability, more vendor independence, possibility of network virtualization, lowered operational expenses, etc. SDN deployments are possible a variety contexts: Enterprise networks, WANs networks connecting centers. The realization operation an requires inclusion central controller. however raises...

The considerable increase of multimedia services, such as video-on-demand (VoD) is a significant contributor to the total Internet traffic. Software-defined networking (SDN) and information-centric (ICN) are two promising technologies that can be combined facilitate video delivery reduce network delays. In this paper, we first formulate caching decision problem 0-1 integer linear programming (ILP) problem. Second, in contrast existing approaches solve formulated ILP by assuming all future...

The virtualization of network functions is promising significant cost reductions for operators. Running multiple on a standard x86 server instead dedicated appliances can increase the utilization underlying hardware,while reducing maintenance and management costs such functions. However, total ownership calculations are typically function attainable throughput, which in virtualized system highly dependent overall architecture - particular input/output (I/O) path. In this paper we investigate...

Media content in its digital form has been rapidly scaling up, resulting popularity gain of cloud computing. Cloud computing makes it easy to manage the vastly increasing content. Moreover, additional features like, omnipresent access, further service creation, discovery services, and resource management also play an important role this regard. The forthcoming era is interoperability multiple clouds, known as federation or inter-cloud With federation, services would be provided through two...
