Slice-aware Capacity Management in Multi-Tenant Networks

5G is envisioned to provide substantial increase in the network performance both in terms of achieved rate and delay. However, in order to satisfy these goals, the network operators are forced to make significant investments on the network infrastructure. Consequently a key question is how to invest the scarce economical resources to achieve maximum impact. Unlike the predecessor technologies, 5G contains a vast amount of services with unique requirements and priorities. From a network operator's perspective, solely focusing on the particular services makes it harder to determine the business value of a region. Therefore, in order to efficiently use the available expansion budget, the conventional approach of network dimensioning has be revisited. In this work, we propose a novel utility function based capacity management framework that can be automatized to dynamically and efficiently manage the infrastructure resources. Build upon three decision metrics, i.e. the urgency of the required resources, available investment budget and the expected impact of the capacity increase, our algorithm determines regions to invest in. Moreover, our analysis shows that the efficiency of the proposed framework does not strictly rely on the long term observation of the traffic demand.

© 1963-2012 IEEE. This article presents a packaged SiGe BiCMOS reflectometer for 0.01-26-GHz two-port vector network analyzers (VNAs). The reflectometer chip is composed of a resistive bridge coupler and two wideband heterodyne receivers for coherent magnitude and phase detection. In addition, a high-linearity receiver channel is designed to accommodate 20 ...

Protecting photonic quantum states using topology

  • Blanco-Redondo A.

The use of topology to protect quantum information is well-known to the condensed-matter community and, indeed, topological quantum computing is a bursting field of research and one of the competing avenues to demonstrate that quantum computers can complete certain problems that classical computers cannot. In photonics, however, we are only ...

  • Weldon M.

This paper takes a fresh look at the debate over the relationship between digital technology and productivity. The argument of economic historian Robert J. Gordon is that digital technology will not lead to increases in productivity such as we saw in the last century, based on his analysis of the ...
