Jugariu, Timo (author)
An all-important step in the ambitious pursuit towards autonomous networks has been the introduction of Software Defined Networking which has advocated the concept of separating a network’s control plane from the data plane and creating a programmable controller with a wider view of the network. This innovation proved to be very promising, but...

In recent years, the use of Software Defined Networking (SDN) has increased due to various network management requirements. Using SDN in computer network applications has brought several benefits to users, including lower operational costs, better hardware management, flexibility, and centralized network deployment. On the other hand, the...

Electrical power grids are vulnerable to cyber attacks, as seen in Ukraine in 2015 and 2016. However, existing attack detection methods are limited. Most of them are based on power system measurement anomalies that occur when an attack is successfully executed at the later stages of the cyber kill chain. In contrast, the attacks on the Ukrainian...

As power system's operational technology converges with innovative information and communication technologies, the need for extensive resilience testing for scenarios covering the electrical grid, networking bottlenecks, as well as cyber security threats, become a necessity. This paper proposes a comprehensive, multi-disciplinary simulation...

Throughout the last decades, communication networks have become embedded into almost every aspect of our day-to-day lives (e.g., watching movies, online shopping, sharing moments with friends and family). Moreover, as the support for the transport of audio and video became the norm, new application domains have kept emerging every day. One of...

Ivaşcu, Darius (author)
The Software Defined Network (SDN) is a relatively new paradigm that aims to tackle the lack of centralization in the existing network by separating the control centre from the programming data plane. The controller keeps an overview of the structure of the whole network, which makes it vulnerable to possible topology poisoning attacks. Topology...

Software-Defined Networking (SDN) is a relatively new networking paradigm that proposes to separate the control and the data logic in networks. The control logic is centralized in a controller, which allows for a programmable network. SDN is promising but also intro- duces some critical security vulnerabilities to networks. This work proposes a...

P4 programmable data-planes provide operators with a flexible method to set up data-plane forwarding logic. To deploy networks with confidence, a switch's forwarding logic should correspond with its intended behavior. Programs loaded onto programmable data-planes don't necessarily go through as much testing as traditional fixed-function devices...

The Internet of Things (IoT) connects smart devices to enable various intelligent services. The deployment of IoT encounters several challenges, such as difficulties in controlling and managing IoT applications and networks, problems in programming existing IoT devices, long service provisioning time, underused resources, as well as...

The Internet of Things (IoT) has and will continue to permeate many aspects of everyday life. However, IoT de- vices often use wireless communication to transfer their data, which may experience ambient noise and multipath fading. This, together with the wide heterogeneity in types of devices, leads to the emergence of unidirectional links in...

Software-defined networking (SDN) is a cornerstone of next-generation networks and has already led to numerous advantages for data-center networks and wide-area networks, for instance in terms of reduced management complexity and more fine-grained traffic engineering. However, the design and implementation of SDN within wireless sensor networks ...

With the high and varying demands for network bandwidth, Elastic Optical Networks (EON), as a promising solution for future optical transport networks, have been getting increased attention due to its flexibility and efficiency. As a huge amount of data is transformed over these networks, even short failures will lead to major data loss. Network...

Openflow is the emerging standard for Software Defined Networking, it allows users to perform routing and run their applications on the network. Such applications can perform diverse tasks such as making Quality of Service guarantees and monitoring/firewalling the network.<br/><br/>Most companies don't actually own datacenters and servers...

The past century of telecommunications has shown that failures in networks are prevalent. Failure recovery processes are therefore needed. Failure recovery is mainly influenced by (1) detection of the failure, and (2) circumvention of the detected failure. However, especially in SDNs where controllers recompute network state reactively, this...

The imminent arrival of the Internet of Things (IoT), which consists of a vast number of devices with heterogeneous characteristics, means that future networks need a new architecture to accommodate the expected increase in data generation. Software defined networking (SDN) and network virtualization (NV) are two technologies that promise to...

QoS (Quality of Service) control is an important concept in computer networking as it is related to end user experience. End-to-end QoS guarantees, in particular, can give firm guarantees to end hosts. Unfortunately, it has never actually been used on the Internet since it was deemed too complicated. With the emergence of Software Defined...

With the increase in data-intensive research in recent years, the Ethernet circuit, which is a high speed point-to-point connection, can be used for transmitting large amounts of data between sites. Customers use the trunk port to connect to the operator network. It allows multiple Ethernet circuits to share the same trunk port by using the...
