UnCLOSE: User-Centric Orchestration of Security in Software-Defined Networks

Nizar Kheir (Thales Group, France); Wafa Ben Jaballah (IEEE, France)

Software-Defined Networks (SDNs) are a promising platform to develop innovative network security services. However, current approaches to operate SDN-based security remain mostly provider-centric. They enable operators to specify security services, and to leverage standard SDN implementations such as OpenFlow, in order to deploy end-to-end policies including, for example, network isolation, monitoring, and incident handling. A common limitation to these approaches is their inability to specify custom, user-centric, security requirements. Users on top of the SDN controller may need to compose specific security services, to monitor threat scenarios that are relevant only to their own contexts, and to devise user-specific mitigation actions. Unfortunately, in today's provider-centric SDN networks, security remains mostly beyond the users' reach, which may lead to security loopholes, yet also vendor lock-ins. This paper introduces UnCLOSE, a User-Centric openfLOw SEcurity management framework, and integrates this framework as part of the SDN control plane. In a multi-tenant SDN platform, UnCLOSE enables users to specify their own security monitoring contexts, and to customize incident handling by associating these contexts with user-specific mitigation actions. UnCLOSE monitors on-the-fly the user-defined security contexts, and triggers appropriate mitigation actions as soon as their associated contexts have been activated. Our framework provides large flexibility for the definition of security monitoring contexts, leveraging both standard OpenFlow statistics and other security-related data such as intrusion detection alerts. We describe in this paper a prototype implementation of UnCLOSE using the open source FloodLight SDN controller, and we use this prototype in order to evaluate different performance and efficiency aspects of our solution.


V2V Communication to Share Intensions for Robust Cooperative Adaptive Cruise Control

Jacco van de Sluis, Ellen van Nunen and Dennis Heuven (TNO, The Netherlands)

Cooperative Adaptive Cruise Control (CACC) is used as solution to improve traffic throughput and reduce fuel consumption. Vehicle-to-Vehicle (V2V) communication is applied to allow for short vehicle following distances. Intended accelerations are exchanged from the preceding vehicle to the following vehicle by the CACC control application. To remain safe and stable, in case of a communication failure, the following distance or time gap must be increased. Since this increase in time gap is not instantly realizable, the CACC design must be robust against intermittent V2V failures. In this study a model based prediction (MPC) design is used for the CACC controller. Instead of broadcasting a single intended acceleration (as done in many other studies), this study proposes to share the predicted future intended accelerations, which is determined by the MPC controller. This however requires a change in the message set definition in which a variable length vector is used depending on the actual prediction length. Sharing the vector with intensions offers more robustness against V2V packet drops. Also it allows to interpolate the communication frequency to the, typically higher, frequency of the CACC controller. From tests with experimental vehicles, the design is evaluated and it shows control performance has been increased, also in periods with packet loss.

The emergence of new kind of use cases such as the Internet of Things (IoT) pushes future wireless technologies to be more than a simple incremental evolution of currently deployed one. The joint ever-increasing number of devices and the large service range to be supported strongly encourages an efficient bandwidth use. High side lobe rejection and improved flexibility are therefore key challenges for future wireless technologies. In this context, filtered-based waveforms are likely to be preferred over the legacy CP-OFDM suffering for a poor spectral confinement. Recently, Block-Filtered OFDM (BF-OFDM) has been proposed. This waveform is a precoded filter bank based scheme providing improved frequency localization while ensuring Near Perfect Reconstruction (NPR). Besides, the receiver scheme is reduced to a simple FFT as in CP-OFDM which preserves backward compatibility with LTE technology.

The concept presented in the poster defines an architectural framework that provides a bridge between 3GPP and 5G PPP approaches to network slicing. Moreover it includes some concepts that were missed or not addressed properly in the analyzed approaches, like: inclusion of legacy systems, sub-slices, per plane slicing, split of functions between the common slice and dedicated slices, multi-domain recursive slicing, on-demand slicing support and more.

Michael Boniface and Simon Crowle (University of Southampton, United Kingdom (Great Britain)); Stephen Phillips (IT Innovation Centre, United Kingdom (Great Britain)); Jessica Rosati (University of Southampton, United Kingdom (Great Britain)); Dirk Trossen (InterDigital Europe, United Kingdom (Great Britain)); Gino Carrozzo (Nextworks s.r.l., Italy)

The H2020 FLAME project is developing an Experimentation-as-a-Service (EaaS) methodology for building urban scale media ecosystems. Using a flexible media service platform deployed within real-life smart city infrastructures, the approach allows exploration of key benefits of adaptive software-defined and cloudified network infrastructures including mobile edge computing. FLAME initial experiments include multiple stakeholder roles (platform provider, media service provider, consumers), each exploring acceptance and viability from different perspectives of envisaged value networks. FLAME experiments will provide the core knowledge on optimal redistribution of information and control, thus inspiring how commitments and obligations can be codified in Service Level Agreements for potential future B2B and B2C relationships.

Tom Jones and Gorry Fairhurst (University of Aberdeen, United Kingdom (Great Britain)); Eric Vyncke (Cisco, Belgium)

The UDP Socket API has matured to support a wide range of uses, while only offering minimal services to applications. This poster describes the high-level Datagram API offered by the NEAT System and how this enables applications to take advantage of information about the available network services, to effectively use next generation networks.

Seyed Pooya Shariatpanahi (Institute for Research in Fundamental Sciences (IPM), Iran); Hamed Shah-Mansouri (University of British Columbia, Canada); Babak Hossein Khalaj (Sharif University of Technology, Iran)

We consider the effect of Channel State Information (CSI) estimation error on the throughput of one-hop Device-to- Device wireless networks under the random connection model. Naturally, as the transmission strategy is designed based on CSI, this error degrades network throughput. However, interestingly, our results show that if this error is below a given threshold, network can tolerate it without any significant throughput loss.


Development of a Smart Spectrum Access Prototype

Hiroki Iwata and Kenta Umebayashi (Tokyo University of Agriculture and Technology, Japan); Janne Lehtomäki (University of Oulu, Finland); Miguel López-Benítez (University of Liverpool, United Kingdom (Great Britain)); Shusuke Narieda (National Institute of Technology, Akashi College, Japan)

In this poster, concept and development of smart spectrum access (SSA) are shown. SSA corresponds to an enhanced dynamic spectrum access (DSA) and the enhancement is achieved by prior information about spectrum utilization by primary uses (PUs). Specifically, secondary users (SUs) can utilize vacant spectrum licensed to PUs based on the prior information more efficiently compared to typical DSA. One important issue in SSA is the implementation of the function obtaining the prior information. For this issue, a two layer architecture has been proposed and it consists of the first layer corresponds to a DSA system (DSAS), and the second layer is a spectrum awareness system (SAS) which is dedicated for spectrum usage measurement and obtaining the prior information. In our poster, the concept of SSA, developed SAS prototype based on multiple sensors, and some developed signal processing methods for SAS are shown. The experimental results demonstrate the validity of SAS and the concept of SSA.
