Re: Has virtualization become obsolete in 5G?

[Etienne-Victor Depasquale <edepa () ieee org>]

I think that it's validation of QoS that really matters now.

If I were to base on this recent video from Keysight
<https://www.keysight.com/zz/en/events/america/webinars.html?D2C=2036435&isSocialSharing=Y&partnerref=emailShareFromGateway>
(warning:
requires registration),
then it seems that there's a lot of emphasis on making grounded claims
about the QoS that the operator sells.

Cheers,

Etienne
