Redefining Desktop Delivery via
Samsung’s Cloud Display PCoIP
Zero Clients
A resurgence in VDI and DaaS has enabled Samsung to
showcase their latest range of Cloud Display Clients.
R
cently there has been a resurgence
of the technologies known as “Virtual
Desktop Infrastructure” (VDI), and most
recently branded “Desktop as a Service” (DaaS) solution offerings, which
apply the described methodology to an
additional enterprise services realm – the
Enterprise Desktop.
While most Cloud-aware products and services are designed to be delivered via a web browser or mobile device
application, there are scenarios where the capabilities and
power inherent in a device and web access mechanism
exceeds that which are required for a fully-fledged Desktop
Experience. For these situations, businesses require a new
way of thinking in order to deliver the best “near Desktop”
experience to their user base.
Samsung is pushing the envelope with their pioneering
Cloud Display range of zero clients. Samsung has provided users with end user devices that are both svelte and
elegant while delivering a no-sacrifice desktop experience.
Samsung has focused on building the best possible zero client devices while utilising the least amount of physical desk
real estate, says Ryan Leih, Senior Virtualisation Engineer
at Cybervine IT Solutions.
The Samsung NC241, NC191 and NB-NH cloud display
zero clients all feature the latest Teradici TERA2 PCoIP
offload processor, specifically designed to offer the best
possible desktop delivery for users via the PCoIP protocol.
And while both the NC241 and NC191 come as complete
units with screen and zero client in one, the NB-NH units
ship as a zero client monitor stand on which you can attach
any VESA mount compatible monitor – therefore facilitating
an upgrade path for clients with existing hardware.
Grant Vine, Solutions Architect at Cybervine goes on to
describe the PCoIP protocol as much like watching a TV
channel. Screen updates are streamed to the user with an
acceptable level of packet loss allowed as the human eye
simply cannot take in an entire screen update as a single
view. Optimisations are made around the successful and
clear delivery of the current eye’s focal points such as the
location of the mouse cursor or keyboard cursor. Multiple
algorithms are at work in the background that the Samsung Cloud Display devices are specifically designed to
understand and maximise – this is the power of the TERA2
processors over a traditional Thin Client running a more
generalised approach to remote desktop delivery.

Using the concepts of already proven technologies such
as Voice or Video over IP (VoIP), such as the use of UDP
as the streaming protocol, the PCoIP protocol is able to
inherit many of the same optimisation and traffic management mechanisms already in existence for these services.
Samsung’s Zero Clients additionally support Quality of
Service (QoS) markings directly from the Zero Client,
exactly like existing Voice platforms operate, thus allowing for end to end QoS management. In fact, the network
traffic is so similar and uses many of the same network
packet matching definitions of VoIP, that the integration
of a PCoIP delivered solution onto a network already
optimised for VoIP can inherit some of those same optimisations for remote desktop delivery – both on the WAN
and LAN infrastructure if end-to-end VoIP QoS has been
implemented.
