Thomas Lentz, solution manager of innovative services at Singtel and Markus Feldbruegge, network consultant at Henkel, share their case study of a successful SD-WAN deployment to a existing hybrid network.
The inaugural WAN Frankfurt conference kicked off today with
opening remarks from Greg Bryan of Telegeography who spoke of
costs concerns, challenges and opportunities in the WAN
Starting off the event, Thomas Lentz, solution manager of
innovative services at Singtel and Markus Feldbruegge, network
consultant at Henkel, the German beauty, laundry and homecare
company, shared with us 'the success story’ that
is their SD-WAN deployment.
Henkel started with 450 locations in across 70 countries,
53,000 employees from 120 nations globally. The
company’s goal was to attain the agility to be
fast on the market, digitalisation, short lead times and to
bring everything to the business as quickly as possible.
The network, before Henkel and Singtel began implementing
SD-WAN, had in most locations a hybrid network of MPLS and the
Internet. As a starting point Henkel already had cloud
enablement, internet offloading for all cloud-based traffic,
high internet and MPLS bandwidth, the challenge was how to
position SD-WAN in such a network?
Because Henkel’s existing hybrid network
addressed so many of the reasons for deploying SD-WAN in the
first place, the two identified a few key challenges that
SD-WAN could solve these are: Application-based routeing and
fully meshed networking, security, visibility and lead
The way in which Singtel addressed these challenges was to
create an overlay network on top of the existing infrastructure
independent of any providers, with a single point of visibility
over the whole network.
Because of the complexities of changing existing networks to
either just MPLS or just internet, Singtel was sure to keep
Henkel’s existing underlying network as the key
component and used the overlying network to give the increased
control and above all security the enterprise greatly needed.
Through the Singtel solution, they gave Henkel a security
domain, full encryption independent of technology.
The next feature was centralised management to help Henkel
manage all of its external warehouses, using SD-WAN they were
able to take all the various connectivity types from the
different sites and link them back into the network. They were
also able to use to the platform to simplify the delivery and
configuration. There are a few templates which can be used to
speed up the process enabling deliver in a matter of minutes
that can be offered through Singtel as either a managed service
or as a self-service option.
The next is performance aware routing which Lentz said is
one of the 'key elements’ when we talk about
SD-WAN in general and an added value to Henkel’s
deployment. He went on to discuss service chaining and cloud
integration. Using a SD-WAN box, which he said can be
integrated into the cloud, the cloud becomes one of your sites
within your network.
Feldbruegge, added that Henkel chose Singtel as its carrier
of choice because of its innovation in technology around the
platform it uses, cost reduction, because it is a global player
and its operational experience.
Neither Feldbruegge nor Lentz see SD-WAN going anywhere in
the next 3-5 years and while we are still on the journey, he
sees that the majority of networks will move to SD-WAN in the
