On slice isolation options in the transport network and associated feasibility indicators

Proceedings of: IEEE 7th International Conference on Network Softwarization (NetSoft 2021)Isolation is one of the more relevant attributes associated to the idea of network slicing, introduced by 5G services. Through isolation it is expected that slices from different customers could gracefully coexist without interfering each other, in the sense that whatever misbehavior or unforeseen demand from one slice customer could not affect the communication service received by any other slice customer supported atop the same physical transport infrastructure. This paper surveys and compare different technical approaches that can be taken for providing distinct isolation levels in the transport network, as a major component of end-to-end network slices. Furthermore, a number of isolation feasibility indicators are defined and proposed. These indicators are based on the approaches referred before, as a mean of guiding orchestration decisions at the time of provisioning or reconfiguring the transport slices in the network.This work has been partly funded by the 5G-PPP projects 5G-DIVE (Grant Agreement no. 859881), 5GROWTH (G.

5G-CLARITY: Integrating 5GNR, WiFi and LiFi in private networks with slicing support

This paper introduces 5G-CLARITY, a 5G-PPP project exploring beyond 5G private networks integrating heterogeneous wireless access including 5GNR, WiFi, and LiFi. The project targets enhancements to current 5GNR performance including multi-connectivity and indoor positioning accuracy. It also develops novel management enablers that allow to operate the private network with a high level intent interface, while being able to natively embed Machine Learning (ML) functions.This work is supported by the European Commission’s Horizon 2020 research and innovation program under grant agreement #871428, 5G-CLARITY project.Peer ReviewedPostprint (author's final draft
