We present three approaches for the same multi-domain defensive action that can be applied in such an alliance: 1) Counteract Everywhere, 2) Minimize Countermeasures, and 3) Minimize Propagation. First, we provide a formula to compute efficiency of a defense; then we use this formula to compute the efficiency of the approaches under various circumstances. Finally, we discuss how task execution order and timing influence defense efficiency. Our results show that the Minimize Propagation approach is the most efficient method when defending against the chosen attack.' author: - first_name: Ralph full_name: Koning, Ralph last_name: Koning - first_name: Gleb full_name: Polevoy, Gleb id: '83983' last_name: Polevoy - first_name: Lydia full_name: Meijer, Lydia last_name: Meijer - first_name: Cees full_name: de Laat, Cees last_name: de Laat - first_name: Paola full_name: Grosso, Paola last_name: Grosso citation: ama: 'Koning R, Polevoy G, Meijer L, de Laat C, Grosso P.

However, as it is not feasible to realise all types of VNFs in CNs, the coexistence of VMs and CNs is proposed. To put VMs and CNs together, an orchestration framework that can chain services across distributed and heterogeneous domains is required. To this end, we implemented a framework by extending and consolidating state-of-the-art tools and technologies originated from Network Function Virtualization (NFV), Software-defined Networking (SDN) and cloud computing environments. This framework chains services provisioned across Kubernetes and OpenStack domains. During the demo, we deploy a service consist of CN- and VM-based VNFs to demonstrate different features provided by our framework. author: - first_name: Hadi full_name: Razzaghi Kouchaksaraei, Hadi id: '60845' last_name: Razzaghi Kouchaksaraei - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Razzaghi Kouchaksaraei H, Karl H.

The considered flows are non-interactive because they do not explicitly target the end users. However, most of them must be performed on a timely basis and are associated with a deadline. We propose to schedule these flows by a centralized controller, which determines when to transmit each flow and which path to use. Two scheduling models are presented in this paper. In the first, the controller also determines the rate of each flow, while in the second bandwidth is assigned by the network according to the TCP rules. We develop scheduling algorithms for both models and compare their complexity and performance. author: - first_name: R. full_name: Cohen, R. last_name: Cohen - first_name: Gleb full_name: Polevoy, Gleb id: '83983' last_name: Polevoy citation: ama: Cohen R, Polevoy G.

It allows customers to easily scale their infrastructure and save on the overall cost of operation. However Cloud service offerings can only thrive if customers are satisfied with service performance. Allow-ing instantaneous access and flexible scaling while maintaining the service levels and offering competitive prices poses a significant challenge to Cloud Computing providers. Furthermore services will remain available in the long run only if this business generates a stable revenue stream. To address these challenges we introduce novel policy-based service admission control mod-els that aim at maximizing the revenue of Cloud providers while taking in-formational uncertainty regarding resource requirements into account. Our evaluation shows that policy-based approaches statistically significantly out-perform first come first serve approaches, which are still state of the art. Furthermore the results give insights in how and to what extent uncertainty has a negative impact on revenue. author: - first_name: Tim full_name: Püschel, Tim last_name: Püschel - first_name: Guido full_name: Schryen, Guido id: '72850' last_name: Schryen - first_name: Diana full_name: Hristova, Diana last_name: Hristova - first_name: Dirk full_name: Neumann, Dirk last_name: Neumann citation: ama: 'Püschel T, Schryen G, Hristova D, Neumann D.
