By providing high flexibility and abstraction of network resources and functions, network slicing allows to partition a single physical infrastructure in multiple logical independent networks, called slices. To guarantee the required network performances, slices need to be logically isolated from each other. Therefore, advanced mechanisms are needed to efficiently manage the resource sharing among slices. On one side, static slicing guarantees full isolation but requires overprovisioning of the resources. On the other side, dynamic slicing exploits multiplexing gains by sharing resources among slices. In this work, we compare the two resource allocation schemes and propose a metric to quantify the slicing gain. We show that, also under critical constraints, e.g. in terms of stringent latency and throughput requirements, dynamic slicing outperforms the static approach.

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 ...
