In this work we describe the process of deploying virtual routers in accordance with flexible time allocation of virtual access to the processor. We developed the model of software router with a set of modern mechanisms and algorithms service information flows. Using the model of the router we enhanced functionality of the device: added mode of deployment of virtual nodes with the possibility of flexible...
This paper presents the contributions of the phd thesis “Mechanisms for management of SLA for Virtual Software Defined Networks based on QoS Classes”. Over the years the Internet has become the primary means of communication, where the users expect to access the Internet anytime, anywhere, and with a certain quality level. As a consequence, in the past few years the traffic demand to Internet access...
Software Defined Networking and Network Function Virtualisation provide significantly more flexibility and control when provisioning QoS for delay sensitive services. Network delay can have a detrimental impact on VoIP quality and, therefore, minimising delay can help maintain the quality and prevent call dropping. This paper proposes a queuing scheme based on packet delay for prioritising VoIP calls...
The continuous increase in data traffic, heterogeneous access networks, and the diversity in the Quality of Service (QoS) requirements of the applications is expected to significantly increase the management complexity of 5G networks. Software Defined Networking provides an effective management architecture enabling more efficient utilization of 5G network resources. In this paper, a novel failure...
MTC services are undergoing rapid increase; billions of MTC connections can be anticipated in a few years. When supporting MTC services in telecommunications networks, MTC traffic characteristics and its unique service requirements should be exploited in order to optimize resource utilization and offer satisfactory service quality for all devices. In this paper, we present an Information-Centric Virtual...
The Intel® Omni-Path Architecture (Intel® OPA) is designed to enable a broad class of computations requiring scalable, tightly coupled CPU, memory, and storage resources. Integration between devices in the Intel® OPA family and Intel® CPUs enable improvements in system level packaging and network efficiency. When coupled with the new user-focused open standard APIs developed by the OpenFabrics Alliance...
The paper describes the testbed to determine the effectiveness of an approach to build network storage using Software-Defined networks (SDN) OpenFlow. It is assumed that main protocol to SAN is iSCSI over local area network. Prototyping tools for managing network resources and data flows on the basis of SDN and testing environments based on Free and Open Source software. We describe experiments with...
Software defined Networking (SDN) such as Open-Flow decouples the control plane from forwarding devices and embeds it into one or more external entities called controllers. We implemented a framework in OpenFlow through which business customers receive higher Quality of Service (QoS) than best-effort customers in all conditions (e.g. failure conditions). In the demonstration, we stream video clips...
Multi-Technology Operations System Interface (MTOSI) as an open interface has been proposed by TM-Forum in 2003. It not only supports the interactions between EMS-NMS like MTNM, also it generalizes the logic, and can be used for the communications between the other operations systems involved in the OSS. In this work, we first proposed the novel modular structured OSS functional architecture model...
Wireless Sensor Network (WSN) deployment appears like a crucial step for network Quality of Service (QoS). In this context a real conception has to be planed before a deployment on the studied area. Actually researches use a simple and regular Area of Deployment (AoD) representation and do not allow interactive interface for a non programmer. Our approach tries to provide a tool to elaborate a strategy...
Smart phones are starting to find use in mission critical applications, such as search-and-rescue operations, wherein the mission capabilities are realized by deploying a collaborating set of services across a group of smart phones involved in the mission. Since these missions are deployed in environments where replenishing resources, such as smart phone batteries, is hard, it is necessary to maximize...
The paper offers tree-structured connectivity between the peer entities over an infrastructure network as an abstraction to embody the application-oriented processing functions on peer-to-peer information flows. Tree reconfigurations are triggered when failures or security violations occur in the connectivity path between the peer nodes (e.g., increase in path delays, DOS attack on a node). Reconfigurations...
The Department of Electronic Engineering of Beijing Institute of Technology is integrating emerging interconnect technologies with other high-performance technologies to meet the demanding requirement of future, real-time signal processing applications. For next-generation, scalable, modular and adaptable signal-processing system, a universal, flexible and high-performance signal processing module...
In recent years, organizations have been shifting focus to their core business competencies, and reducing total cost of ownership (TCO) associated with training and management of their IT infrastructure. In the same motif, organizations are establishing security and survivability frameworks as an integral part of their business strategy so as to provide an acceptable quality-of-service for their clients...
