Servers in a network are typically assigned a static identity. Static assignment of identities is a cornerstone for adversaries in finding targets. Moving Target Defense (MTD) mutates the environment to increase unpredictability for an attacker. On another side, Software Defined Networks (SDN) facilitate a global view of a network through a central control point. The potential of SDN can not only...
In this poster, we propose leveraging intercontroller communication between two or more controllers in Software Defined Networks (SDNs) to inform other controllers about potential attacks so that they can proactively apply a mitigation strategy. We demonstrate and measure the effectiveness of our method by running a series of tests in an emulated network. We analyze our test results in terms of reducing...
Software Defined Networking (SDN) enables a centralised entity - the controller - to monitor the network’s status by collecting traffic statistics such as packets, bytes, etc. Each statistic is associated with a forwarding table entry (FTE) in a switch whose structure and format is specified by the OpenFlow standard (de-facto SDN standard). For a flow with a FTE, its statistic is easily...
Current approaches to Information-Centric Networking (ICN) facilitate the publication and retrieval of content in a network through a variety of discovery, caching and forwarding approaches, thus defining an equivalent of the data plane in the current Internet infrastructure. However, in contrast to the current Internet, ICN lacks a definition of the control plane for the management of the operation...
The article designed a military grade switchboard with Gigabit POE power capacity through 5 ports by researching switch principle and actual requirement. Firstly, the whole circuit and associated systems were introduced. Secondly, the circuit which used network management chip 88E6161 of Marvel Company and microcontroller chip PD69104B of Micro-semi Company was designed and emulated, the specific...
The rapid proliferation of devices of the Internet of Things requires a vast network of heterogeneous devices to maintain the ability to communicate rapidly and seamlessly. The transition to delay sensitive Tactile Internet applications would demand on a new information and communications infrastructure. In our previous work, we have proposed a fast Location basEd Source Switching (LESS) mechanism...
Accelerator-in-Switch (AiS) is a framework for building an accelerator logic tightly coupled with a switching hub in a single FPGA for high performance computation with heterogeneous environment with CPUs and GPUs. AiS is implemented on a partial reconfigurable region of an FPGA whose permanent region is used for a switching hub. A port of the switching hub is connected to the registers and local...
Software-Defined Networks (SDN) is an emerging area that promises to change the way we design, build, and operate network architecture. It tends to shift from traditional network architecture of proprietary based to open and programmable network architecture. However, this new innovative and improved technology also brings another security burden into the network architecture, with existing and emerging...
Cisco DevNet Always-On APIC-EM Sandbox is useful in the phase of learning about software-defined networking, allowing to perform experiments, but without the possibility to change the topology the extent of development is limited. In this paper a Cisco APIC-EM SDN Controller was installed in a private cloud orchestrated by OpenStack. The major objective was to create a virtualized testbed, consisting...
Network function virtualization (NFV) is a concept aiming to achieve telecom grade cloud ecosystem for new generation networks focusing on Capital and Operational expenditure (CAPEX and OPEX) savings. Keeping at least the same performances is one of the main requirements of the applications when being virtualized. This work presents a performance impact of Open Virtual Switch (OVS) user-space forwarding...
This paper presents a visual comfort considered light control method for energy savings in open-plan office and investigates its performance. Simulation and pilot testing results show that more than 60% energy savings could be achieved while providing recommended visual comfort level for each user. Since the proposed algorithm saves energy significantly compared to the previous light control policies...
Supervisory Control and Data Acquisition (SCADA) systems are used in many industries, particularly in the control of nationwide electric grids. These systems may by law, technical obsolescence, or failure, need to be replaced by newer ones. However, the testing and handing over of functions from the old SCADA to the new one (i.e., switchover) has to be done with minimum risk and maximum continuity...
Everything can be mobile, from end-hosts to applications. The need for mobility management is rising rapidly due to the increasing number of mobile devices and the advent of new types of mobile object, such as Internet of Things devices, connected vehicles, wearable devices, and virtual machines. In order to support various types of mobility, we propose an integrated and distributed mobility management...
Ethernet plays an important role in the layer 2 network. Unfortunately, the tremendous Address Resolution Protocol (ARP) broadcast traffic among massive hosts limits the scale of Ethernet. Recently, Software-Defined Network (SDN) has been proposed to suppress broadcast traffic by centralized control. However, existing approaches based on SDN suffer from an adaptability limitation as they cannot independently...
A Named Data Networking (NDN) router can maintain a record in its PIT for every Interest packet and leverage PIT table to achieve the goal of stateful forwarding. In this paper, a more general application scene that presents new challenges for stateful forwarding is considered. The network element needs to keep states of previously forwarded packets to determine the forwarding behavior of subsequent...
Honeypots have been largely used to capture and investigate malicious behavior through deliberately sacrificing their own resources in order to be attacked. Hybrid honeypot architectures consisting of frontends and backends are widely used in the research area, specially due to the benefits of their high scalability and fidelity for detailed attacking data collection. A hybrid honeypot system often...
We present a new method to translate the established and well-known ConcurTaskTree (CTT) task modeling technique into state machines. For this purpose, we develop the concepts of partial state machines, Connectables and a connect operator, which form the theoretical framework for a new algorithm. For the translation, we develop and present a recursive, bottom-up algorithm, which exploits the inherent...
In this paper, we propose a hardware-based defense system in Software-Defined Networking architecture to protect against the HTTP GET Flooding attacks, one of the most dangerous Distributed Denial of Service (DDoS) attacks in recent years. Our defense system utilizes per-URL counting mechanism and has been implemented on FPGA as an extension of a NetFPGA-based OpenFlow switch.
This paper presents a SAR ADC using passive noise shaping and noise quantizer techniques. A ping-pong residue switching enables noise shaping at high sampling rate. The prototype in 14 nm achieves 69-dB SNDR at 25-MHz BW and 300 MS/s. The FOMs and FOMw are 169 dB and 20.5 fJ/conv.-step, respectively. With noise shaping only, the SNDR is 66.2 dB at 33-MHz BW and 400 MS/s.
In this paper we present the engineering of a non-volatile 1S1R memory based on a Phase-Change Memory cell (PCM), consisting in a GeN/Ge2Sb2Te5 layer, stacked with a GeSe-based Ovonic Threshold Switching selector device (OTS). We optimize and analyze separately the two devices, and we propose for the first time an innovative reading strategy of the cross point device, enabled by the improved sub-threshold...
