Failing to make use of multi-path advantages in data center networks (DCNs) has confined accessible resources and increased the possibility of congestion. In this paper, we have presented a new algorithm for traffic engineering (TE) in a modular mode. In the proposed algorithm, the less loaded paths for conduction of current are selected with regard to the present conditions as soon as a current is...
Vehicular Ad-hoc Networks (VANETs) has witnessed significant attention from academia and industries, due to the growing number of applications and devices focusing on safety and efficiency in transportation. Video Streaming in Vehicular Communication (VSVC) presents interactive real-time view of an emergency incidence on roads. On-board unit of vehicles are utilized for streaming real time video of...
This paper concerns the smart exploitation of multimodal communication capabilities of underwater nodes to enable reliable and swift underwater networking. To contrast adverse and highly varying channel conditions we define a smart framework enabling nodes to acquire knowledge on the quality of the communication to neighboring nodes over time. Following a model-based reinforcement learning approach,...
This paper studies enhancement of Multi-Path TCP(MPTCP), which is one of new transport-layer protocols of TCP/IP protocol suites, by IP routing for improvement of Quality of Experience for a Web service (WebQoE). In order to confirm the effect of IP routing on WebQoE, the author performed experiments with subjects. In the experiment, the subjects assess Quality of Experience of two actual Web services...
In this paper for the first time the mathematical model and the two-level method of fault-tolerant inter-domain routing in telecommunications networks was presented. The novelty of the model is its decomposed representation and formulation the inter-area interworking conditions. The implementation of these conditions guaranteed the connectivity of calculated inter-area paths. The research of the proposed...
The purpose of this research is to address the issue of enhancing the Quality of Service(QoS) in IP networks, to make it more optimal in a given network of networks using a novel approach. In this approach, QoS is provided to the packet even when the packet crosses its access network into the backbone. It proposes a new design or set of features in the routers which maps and translates the QoS provisioning...
In this paper, we propose a policy-based model to achieve end-to-end (E2E) service negotiation among multiple domains that constitute E2E path. The model relies on a centralized approach, realized via the third party (3P) agent, which acts as a proxy server for local (per-domain) management entities. We demonstrate the proposed model on the implementation of policies for allocation of performance...
This paper proposes a technique to split a traffic in a software-defined network using a meter table. In general case, a different differentiated services code point (DSCP) number in a packet header is used to classify network traffic and provide quality of service (QoS). The traffic splitting technique uses a DSCP number as a split parameter. Once a packet exceeds a predefined traffic rate, the DSCP...
The growing data traffic demand is forcing network operators to deploy more base stations, culminating in dense heterogeneous networks that require a high-connectivity backhaul. This scenario imposes significant challenges for current and future cellular networks, and Software Defined Networking (SDN) has been pointed as an enabling technology to overcome existing limitations. This paper shows how...
The increase in number of users in Wireless Mesh Networks (WMNs) setups consequently represents an upsurge in numbers of services. Services such as internet, e-commerce, audio streaming, Voice over Internet Protocol (VoIP), Video on Demand (VoD), file and printer sharing among others will be clogged and ran over WMNs. This further leads to poor Quality of Service (QoS). Quick and timely discovery...
Information-Centric Networks (ICN) is a communication paradigm that promises to transfer the Internet from a host-to-host communication network to a massive information delivery system, capable of supporting the future needs of the users. ICNs are based on three main concepts: content forwarding, in-network caching, and multicasting. To realize these three key concepts, Software-Defined Networking...
Minimizing the energy consumption and hence extending the network lifetime is a key requirement when designing an efficient sensor network protocol. QoS-aware routing in Wireless Sensor Network (WSN), aims to take into account other networks performance aspects as minimizing end-to-end delay (as well as jitter), reducing packet loss rate and minimizing the energy consumption of the network during...
Network technology is being developed as a next-generation network (NGN) which is a software-defined networking. The network management can be done directly from the control unit that separated from the transmission unit, called as a forwarder and decoupling controller, which makes efficient network management. In the near future, the next generation network will be used to replace a traditional network...
We present in this paper a multi-layer scheme for QoS Management in MANETs. Our proposal is to combine multiple communication protocols of different layers, to provide an adapted QoS to a different traffic classes. Protocols are modified to improve their awareness of the quality of service, so that new extensions with QoS support are developed. We model QoS service at routing layer, via a QoS extension...
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...
In tactical networks, the quality of service of flows which demand an assured data rate requires connection admission control, and this process can be strongly improved by coupling it with QoS-oriented routing. The TACOMS phase 2 intelligent routing solution does not only choose paths according to their ability to provide a specified data rate, it can also select the route of a flow as a function...
Electronic devices and sensor networks have witnessed great advancements. Consequently, their limited resources (CPU, memory, bandwidth, and power) are becoming suitable to accommodate some of the enterprise networks solutions. One possible and effective solution is Middleware technology that is able to provide several advantages such as simplifying applications development, portability, scalability,...
This paper proposes an improved mesh path selection protocol for QoS support in wireless mesh network, while avoiding the inherent problems of proactive and reactive path selection elements. The proposed ‘Advanced Selective Greedy’ (SelG+) path selection protocol operates in two phases. In the first phase it constructs a set of potential forwarders for every mesh stations. In the second phase during...
This paper presents new Software Defined Networking (SDN) control framework for Quality of Service (QoS) provisioning. The proposed SDN controller automatically and flexibly programs network devices to provide required QoS level for multimedia applications. Centralized control monitors state of the network resources and performs smart traffic management according to collected information. Beside QoS...
Traffic Flow Confidentiality (TFC) aims to prevent analysis of traffic flows. According to the principles of Protected Core Networking (PCN), TFC should be provided as a service in the network and not implemented by the users. Since provisioning of TFC in the entire network might not be practical or economical feasible, solutions are required for forwarding traffic on paths where sufficient TFC is...
