The functional efficiency of cloud solutions depends on their responsive allocation of processing resources to individual tasks according to their predefined completion time. An optimum usage of resources requires an accurate prediction of resource consumption. In this paper we introduce a novel method for predicting the resource consumption of processing requests in multiple consumption classes in a system consisting of a plentitude of processing units. We further enhance the prediction algorithm with different mechanisms to determine the request resource consumption of a variety of request classes in order to increase the precision of the prediction. We also show that the prediction algorithm is robust against abrupt and large variations of consumption and recovers itself rapidly.Index Terms: Resource consumption prediction, resource allocation, Machine Learning, adaptive algorithms, network softwarization, cloud computing, distributed systems.

Fair Dynamic Spectrum Management for QRD-Based Precoding with User Encoding Ordering in Downstream G.fast Transmission

In next generation DSL networks such as G.fast, employing discrete multi-tone transmission in high frequencies up to 212 MHz, the crosstalk among lines reaches very high levels. To precompensate the crosstalk in downstream transmission, QRD-based precoding has been proposed as a near-optimal dynamic spectrum management (DSM) technique. However, the performance ...

Practical Mitigation of Passive Intermodulation in Microstrip Circuits

This paper presents new experimental evidence and a novel practical approach for mitigation of passive intermodulation (PIM) in microstrip circuits fabricated on commercial printed circuit board laminates. The mechanisms of distributed PIM in microstrip circuits are reviewed and a phenomenology of PIM generation due to locally enhanced electromagnetic fields at ...

Efficient Cooperative HARQ for Multi-Source Multi-Relay Wireless Networks

In this paper, we compare the performance of three different cooperative Hybrid Automatic Repeat reQuest (HARQ) protocols for slow-fading half-duplex orthogonal multiple access multiple relay channel. Channel State Information (CSI) is available at the receiving side of each link only. Time Division Multiplexing is assumed, where each orthogonal transmission occurs ...
