Mixed thoughts from panel at Day 2 of WAN Frankfurt, on the best provider strategy for hybrid WAN deployments
Day 2 of WAN Frankfurt was kick started with a panel on
provider selection strategies for hybrid WAN. Panellists
included Jason Poole, principal product marketing
manager, Citrix; Dietmar Geiler, head of product
management & presales, ngena; Facundo
Musante, global network services
manager, Schlumberger and Johan Ottosson, VP of
strategy at Telia Carrier. Moderated by Elliott Cheresh,
research analyst at Telegeography.
On the topic of SD-WAN and its ability to facilitate a
multi-vendor strategy Musante
says that for "many years we [Schlumberger]
has had a multi-vendor setup. In one way or another I
don’t see SD-WAN changing that."

But he keen to point out that whether it’s one
or multiple vendors, the key is trust and whether or not these
businesses trust vendors to manage their applications.
'Most enterprises aren’t concerned with the
pipes coming into their building (unless it goes wrong), their
interest is in the applications,’ says Jason
'The perception is that SD-WAN is easier, but to integrate
it is very complicated,’ says Geiler.
Although Poole disagreed saying: 'to me, the demarcation of
SD-WAN is pretty clear, in some cases the SD-WAN helps, with
what’s working and what’s not."
Ottosson seemed more in favour of a single vendor that is
able to offer an overlay that can cover an underlay source from
Musante "it is my impression that the use of a single
overlay management is attractive, in the case of us doing it
ourselves verses it managed by someone else, we are not in the
business of managing networks.SD-WAN is creating huge
opportunities particularly in the subscription model base,
where we are not tied to a contract, as well as virtualisation
and the feature set that brings the application and the network
