Without breaking the original industrial automation system architecture, it is an important research topic to apply cloud computing to the current automation system in order to realize the function of industrial big data processing, optimizing control and intelligent decision making on the cloud platform. An industrial cloud experimental platform architecture based on OpenStack is proposed in this...
Leveraging Software-Defined Networking (SDN) and middleboxes, application-level policies can be propagated to the network. SMART is an SDN middlebox architecture that differentiates network flows based on tenant inputs. By leveraging FlowTags software middlebox in addition to the OpenFlow rules, it supports a larger scope of tenant preferences and rules from the application layer to alter the network...
In its current form, OpenFlow, the de facto implementation of SDN, separates the network's control and data planes allowing a central controller to alter the match-action pipeline using a limited set of fields and actions. To support new protocols, forwarding logic, telemetry, monitoring or even middlebox-like functions the currently available programmability in SDN is insufficient. In this paper,...
In this paper, we propose a novel cellular network architecture including network virtualization controller for mobile core and backhaul sharing. Software-Defined Networking (SDN) based network virtualization is applied into Evolved Packet System (EPS) architecture of Long Term Evolution (LTE) networks. After virtualization of all evolved Node-Bs (eNodeBs) associated with different Mobile Operators...
In the current development of renewable energy production, microgrid control is a stringent issue nowadays. This practical approach should benefit of the newest automation and IT&C techniques. The paper addresses, in a particular manner, the main control systems strategies and techniques adapted for the microgrid processes: hierarchical control, model predictive control, multi-agent systems, average-consensus...
The emerging Fog Computing paradigm provides an additional computational layer that enables new capabilities in real-time data-driven applications. This is especially interesting in the domain of Smart Grid as the boundaries between traditional generation, distribution, and consumer roles are blurring. This is a reflection of the ongoing trend of intelligence distribution in Smart Systems. In this...
The outstanding advances in computing as well as the explosion of devices and services requirements are making communication mobile networking more and more complex to manage. In addition, multimedia services such as provided by the IP Multimedia Subsystem (IMS) require a dynamic Quality of Service (QoS) management. However, traditional Long Term Evolution (LTE) networking approaches have become too...
Software Defined Network (SDN) is disruptive networking technology. In this paper, we will address some of the major vulnerable areas in SDN. We express some of the unique ways that an adversary can use to attack either the SDN controller or the communication devices. We have used a policy based approach to mitigate these attacks towards the SDN domain. We have implemented our Policy Based approach...
The security of cloud environment is always a target for attackers in order to exploit any of the system's vulnerabilities. Recently, software-defined systems (SDS) has become a focus of several researches. Where, SDS is in the way to replace the traditional networking, in order to provide facilities which are based on remote and centralized control. The security of SDS is a major requirement to guarantee...
Software Defined Networking is an emerging technology that permits computer network infrastructure to be scaled dynamically as needed while enhancing the manageability of the various network devices in heterogeneous environment as opposed to classical networking. These capabilities emerge from the separation of the data plane from the control plane; thus, allowing the network devices to be programmatically...
In this paper, demonstration of failure recovery mechanism was conducted employing nodes developed in Software Defined Network. SDN allows programmability inside a network by providing adaptability towards advancement variation policy usage, as vendor specific policy building confines dynamic application building. In Node failure Recover, first mechanism is Bellman Ford Algorithm (shortest path algorithm)...
Technological advancement of Industrial Control Systems (ICS) and control systems automation over the past decade has brought greater interconnections of the control components. Increased interconnection provides end users with more information which facilitates improved system reliability. Modern control communication systems such as ModbusTCP are based on open standards that leverage Ethernet to...
The main design principle of Information-Centric Networking (ICN) is the name based routing, that makes users able to ask for a data object by only using its name, and makes the network deliver data to users from a nearby cache if in-network caching is available. Software-Defined Networking (SDN) decouples the control layer from the data layer, so that the complexity, and network control and management...
With the number of Phasor Measurement Units (PMUs) in the North American power grid scaling up into the thousands, system operators are gradually inclining towards distributed cyber-physical architectures for executing wide-area monitoring and control operations using Synchrophasors. Traditional centralized approaches, in fact, are anticipated to become untenable soon due to various factors such as...
Software Defined Networking (SDN) has become a popular paradigm for centralized control in many modern networking scenarios such as data centers and cloud. For large data centers hosting many hundreds of thousands of servers, there are few thousands of switches that need to be managed in a centralized fashion, which cannot be done using a single controller node. Previous works have proposed distributed...
“Code Smell” or “Bad Smell”, at the very least, is an indicator of badly for source code and is often analytical of deeper problems in software design. In layman terms, it signals flaws in the core foundation or architecture of the software that can cause any number of more serious problems — from usability and runtime performance to supportability and enhancement. These problems can mostly be prevented...
Outsourcing of sensitive and critical data into third party thus untrusted service environments remains a serious security concern. In such environments, data needs to be protected throughout its lifecycle i.e. at-rest, in-transit and while-in-use. Data in third phase remains mostly unprotected as it demands operations to be performed over encrypted data while achieving semantics same as in case of...
For over forty years, relational databases have been the leading model for data storage, retrieval and management. However, due to increasing needs for scalability and performance, alternative systems have emerged, namely NewSQL technology. NewSQL is a class of modern relational database management systems (RDBMS) that provide the same scalable performance of NoSQL systems for online transaction processing...
The efficiency and maintainability of fault tolerance mechanisms in a computer system has typically not been a major topic of concern, mostly because fault tolerance is a non-functional system requirement. This paper proposes a Holistic Fault Tolerance architecture, based on a centralised fault tolerance management, with related functionality distributed across the entire system. The most suitable...
