The web, seen as a graph of linked resources shared between microservices, can serve as an integration style. It offers unique characteristics and possibilities regarding dataflow, control flow, and other qualities, compared to file transfer, shared databases, remote procedure calls, and asynchronous messaging. Carrying these insights in your toolbox will make you aware of all the options to consider...
Topology control is a crucial process for an efficient operation of a Wireless Sensor Network (WSN). The usage of WSNs in the Internet of Things (IoT) emerges new research challenges and novel applications. Recent WSNs proposals enhanced with Software Defined Networking (SDN) practices introduce new innovative network control strategies and protocols based on central control logic. This paper introduces...
Sleep mechanism(SM) is often used to design green network, however, sleep mechanism must take data loss, network performance and other situations into consideration. Due to hierarchical and centralized control, SDN makes it simple to deploy new applications. SDN is becoming more and more popular in new network applications. In this paper, a new implementation of SM based on SDN is proposed, the SM...
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...
In this paper we proposed policy based security architecture for securing the communication in multiple Autonomous System (AS) domains with Software Defined Networks (SDN). We will present a high level overview of the architecture and detail discussion on some of the important components for securing the communication in multiple AS domains. A key component of the security architecture is the specification...
In this paper we present a proof-of-concept implementation to demonstrate advantages of applying software-defined networking (SDN) to real-time Ethernet (RTE) networks. Potential advantages include the support of arbitrary network topologies, central and dynamic network (re-)configurations, the efficient use of bandwidth, and fast failover mechanisms at network level. To illustrate the advantages...
Real-time services in IP networks require a fast switching of disrupted traffic to alternate paths in case of link/node failures to satisfy their stringent Quality of Service requirements. Multi Topology Routing (MTR) based IP Fast Re-route (IPFRR) technologies rely on virtual topologies to seamlessly forward the IP packets during network failures by activating the proactively computed alternate routes...
A Community Network (CN) is a bottom-up network infrastructure that interconnects communities of people and represents a promising and successful networking model. The more people join a CN, the higher is the demand for a wider range of community services and the need for scalable network protocols. CN designers and passionates hence require adequate frameworks to develop and test different technical...
Software Defined Networking (SDN) is the potential future backbone of all computer networking. The main advantage of SDN is that it separates the control plane from the data plane. This delegates switching/routing decisions to a controller that is connected to the switches. The connectivity of the switches and controllers can be represented as a network topology. Usually a network topology has to...
Currently, the Software Defined Networking (SDN) paradigm has attracted significant interests from industry and academia as a future network architecture. SDN brings many benefits to network operations and management including programmability, agility, elasticity, and flexibility. With SDN and OpenFlow, one of the promising SDN protocols, software defined Network Virtualization (NV) techniques can...
Software defined networking (SDN) has emerged as a promising paradigm for making the control of communication networks flexible. SDN separates the data packet forwarding plane, i.e., the data plane, from the control plane and employs a central controller. Network virtualization allows the flexible sharing of physical networking resources by multiple users (tenants). Each tenant runs its own applications...
Software Defined Network (SDN) is one of the emerging architecture that has captured the attention of networking technology enthusiasts and organizations worldwide. SDN enables programmability of the network, simplifies network management and provides better scope for research. The programmability of the network has made it possible to create software based network components such as hubs, switches...
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...
Software Defined Networking (SDN) introduces the concept of logically-centralized controllers in charge of managing the forwarding behavior of network elements. The new possibilities enabled through the centralization of control logic come with a certain risk: The controller might become a performance bottleneck. Therefore, ensuring sufficient controller performance is one of the crucial tasks prior...
SDN-WISE is a Software Defined Networking solution for Wireless Sensor Networks (WSNs). The aim of SDN-WISE is to simplify the management of the network, the development of novel applications, and the experimentation of new networking solutions in WSNs. Objectives of this demo are to demonstrate how different logical WSNs can coexist exploiting the same sensor nodes and show how easy is it to program...
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...
