Thanks to all who joined us and submitted questions to the HPE SDM Webinar: Subscriber Data Management in the Era of NFV, IoT & Heterogeneous Networks. During the webinar, we learned how Subscriber Data Management (SDM) is at the crossing of the multiple mega-trends that our industry is undergoing: NFV, MVNO/IoT, heterogenous networks and analytics – all force SDM to become more scalable, dynamic and addressable. After the presentation, there was a thoroughly engaging Q&A session. Unfortunately, SDxCentral ran out of time to be able to ask all the questions the audience asked. Read the full Q&A below:
Why is the evolution of SDM happening now? It’s been talked for years, how we know it’s finally happening…
HPE: That’s true. The inefficacy of the siloed SDM approach was known. But until recently it could be dragged on. Now, there are forces of both cost, and competitiveness that force the change:
– More networks – make the inefficacy too costly.
– Need to collaborate with more kind of new operators: IoT, Enterprise and MVNO
– The availability of NFV force CSP to reexamine their cost structure
When do you expect NFV of SDM functions to be adopted widely?
HPE: We see that in 3 waves:
– Virtualization on non-SDM functions push for consolidating of the data-sphere – 1 address to query.
– Virtualization of SDM front-end – early demand for vHSS
– Virtualization of SDM back-end – still not here.
There was an interesting research by IEMR earlier this year. They surveyed many CSPs globally and drew a timeline of adoption that shows:
– NFV driven data convergence – started in 2015
– vFE – early adaptors in 2015, most of the market will complete that by 2018
– vBE – 2017- 2022
How do you see the SDM play between NEPs vs IT/SW vendors?
HPE: It is no secret that a NEP centric approach was dominant in years of massive deployments of access networks (2G, 3G, even 4G to some extent). That’s what created the Siloed SDM reality in many CSP: each NEP when deploying an access network came up with its own propriety SDM. Now, with the strong push to consolidation, and the SW driven approach of NFV, NEPs are losing ground. This is a good time for companies like us, that roots in IT and can bring practices of IT to CSP environments.
