Hidden Storage in Data Centers: Gaining Flexibility Through Cooling Systemsy demand. Thus, the flexibility in shifting energy demand of the cooling systems in data centers could be a great asset for data center operators. The amount of flexibility and how it can be maximized are important yet open problems, due to the several stochastic processes involved. In this paper, w

Performance Benchmarking of Network Function Chain Placement Algorithmsing the . arrangement of such service chains poses new optimization problems, comprising a combination of placement and routing decisions. While there are many algorithms on this topic proposed in literature, this work is focused on their evaluation and on the choice of reference for meaningful asse

Towards Optimal Placement of Monitoring Units in Time-Varying Networks Under Centralized Controlmmon monitoring approaches in the context of such convoluted high-speed networks have become a serious challenge in terms of complexity and resource management. Management functions rely on monitoring information such as the flow size distribution (FSD), to perform crucial activities such as load ba

Estimating the Flow Rule Installation Time of SDN Switches When Facing Control Plane DelayUsing the SDN approach of a separated control and data plane, the controller can order the installation of flow rules in the switches it manages, e.g., via FlowMod messages in case of the OpenFlow protocol. Since the processing time of these messages has a direct impact on the reaction time of the n

Dynamic Control of Running Serversarallel. Using the theory of Markov decision processes and a novel lookahead approach, we explicitly determine near-optimal control policies that minimize a combination of QoE costs, energy costs, and wear and tear costs due to switching. Guidelines are provided as to when these combined policies ar

On the Value of Service Demand Estimation for Auto-scalingasses are actively processed. In a system under load, due to measurement interference, service demands normally cannot be measured directly, however, a number of estimation approaches exist based on high-level performance metrics. In this paper, we show that service demands provide significant benef

Active Queue Management Based on Congestion Policing (CP-AQM)e queuing delay to communication. Active queue management (AQM) accommodates infrequent traffic bursts but avoids a standing queue. Currently, many new AQM mechanisms are discussed in the IETF. In this work, we propose a new AQM mechanism based on the idea of congestion policing. We evaluate its per

Modeling the Performance of ARQ Error Control in an LTE Transmission Systemtic-Repeat-Request functionality at layer 2 of the transmission system. We model the associated window flow control of RLC frames in terms of an open queueing network with two stations and describe RLC frames waiting for acceptance by the flow control window by repeated objects collected in an orbit
