In this work we report experimental tests on the performance of FTTX accesses using the mPlane measurement plane, including lab and field environments and above all we point out the role of such measurement plane in Software Defined Network architectures. For such an aim we show an experimental procedure based on a central unit (orchestrator) that automatically manages GbE links in a regional network...
Wearable devices, such as wristbands, smart-watches, eyewear, and wearable bio-monitors have become the focus of much attention in past year. One in ten U.S. consumers over the age of 18 now owns a modern activity tracker. These ubiquitous devices are a natural platform for formation of ad hoc networks. With almost 40% of users are above the age of 45, these older adopters are focused on improving...
According to Forbes collected data, the public cloud services market will rise in 2016 and is expected to grow to $105 billions and, in fact, Virtual Machines (VMs) are one of the most popular tools for building “Cloud” services. But in service delivery such composition of multiple components greatly complicate analysis of product quality, especially if it is about Voice over IP (VoIP) set of services,...
The growing popularity of outsourced enterprise VoIP services poses a significant quality assurance issue for service providers. VoIP traffic is very sensitive to network impairments and maintaining high QoS across multiple domains can be challenging. We propose to use SDN and our implementation of intermediate VoIP call quality measurement to provide an advanced VoIP monitoring service. Our solution...
Software-Defined Networking (SDN) Architecture is relatively well defined, but the standards still need further development. Currently, working groups are developing Application Programming Interfaces (APIs) in which network monitoring is a priority, because it is the first step towards controlling a network. We present a network monitor that provides basic Quality of Service (QoS) parameters without...
Mobile users today can choose among different competing network operators offers, influenced in their choice by perceived and experienced quality, during the fruition of the service. The network operators must be able to react on quality issues, before the user perceives them. In order to do this, it is essential to establish a link between Quality of Experience (QoE) and Quality of Service (QoS)...
Software Defined Networking is a promising Internet architecture to deliver multimedia with end-to-end quality of service (QoS) since it enables optimal dynamic management of network resources and on-demand QoS provisioning by a network operator. We propose a framework for server load-balancing over a single-operator OpenFlow network to improve the quality of service levels of video streaming services...
Development of machine-to-machine communication technologies encourages an increasing amount of mobile traffic by smart phones, cellular phones, and various sensors. This traffic consists of small packets in order to minimize the influence of frame dropping in a data link layer. However, it is necessary to reduce the number of packets flowing into the core network to chunk packets, while satisfying...
Evolution in Wireless Sensor Networks (WSNs) has allowed new applications that led to an increase in the complexity of communication protocols. This in turn has led to the study of additional Quality of Service (QoS) parameters in order to provide an acceptable system performance. As such, hybrid algorithms that allow sensor networks to perform continuous monitoring (CntM) and event driven detection...
The Quality of Service (QoS) in smart grid communications especially in monitoring smart grid assets is becoming significantly important for emerging smart grid applications. Wireless Sensor Networks (WSNs) are expected to be widely utilized in a broad range of smart grid applications due to their numerous advantages along with their successful adoption in various critical areas including military...
