HP Thin Client Device Recommendations for Unied Communications 42

Introduction

This document is intended to help Virtual Desktop Infrastructure (VDI) administrators deliver the best possible audio

and video call quality experience for their users while reducing resource consumption when using well known Unied

Communications (UC) platforms. Unied Communications encompasses the entire range of modern communication

formats from quick and simple text messaging to full video conferencing and screen sharing. We will cover three

different types of UC optimizations, their strengths, weaknesses, impacts on call quality, and resource usage.

Full UC Optimization (UC Offloading)Full UC Optimization (UC Offloading)

Audio and video call data is processed, sent, and received directly by the participants’ endpoints, bypassing the VDI

solution. Thus, call data will transfer from user to user in less time because it needs to make fewer hops.

Partial OptimizationPartial Optimization

Video call data is compressed at the endpoint before being sent to the VDI solution for processing and redirection to

other call participants. Less data is transferred compared to no optimization, but the additional routing can introduce

extra latency.

USB Webcam RedirectionUSB Webcam Redirection

The USB camera is redirected to the VDI resource using the USB redirection capabilities that are provided by the VDI

solution.

Next, we will explain how to optimize unied communications on different VDI providers like HP Anyware, Citrix

Virtual Apps and Desktops, VMware Horizon, Microsoft Azure Virtual Desktop (AVD) and Windows 365, and Amazon

WorkSpaces according to each solution’s capabilities. Not every VDI solution offers the full spectrum of optimization

options nor supports every leading UC protocol. There are also tips on how to check the optimization’s effectiveness

and troubleshoot potential issues. However, no amount of optimization can overcome an under-resourced endpoint.

So lastly, we provide a comprehensive set of HP Thin Client device recommendations for different situations

including endpoint OS, VDI platform, UC solution, and types of communication. Each situation requires different

resources. Selecting the right HP Thin Client with a performance prole matching your environments’ needs is critical

for your users to have an optimal experience.

Helpful Terminology

Access device refers to any Thin Client computing device that is used to connect across a computer network to

a computer operating system managed by a VDI solution. Within this document we may also refer to this as an

endpoint.

VDI SolutionVDI Solution, as used in this document, refers to any computer operating system that is accessed remotely from

a Thin Client (endpoint) using a solution specic client application, such as Citrix Virtual Apps and Desktops

or VMware Horizon View. While this document mentions some VDI solutions by name, some information and

concepts contained in this document can be applied to other un-named VDI solutions.

Unied Communications (UC)Unied Communications (UC), as used in this document, refers to any computer program that allows end users to

establish audio or video calls between one or more people. These applications may offer other options such as

the ability to share the users screen, applications, or grant remote computer control to other call participants.

UC OptimizationsUC Optimizations, refer to any method utilized within a VDI solution to improve audio or video call quality for end

users. UC optimizations are specic to each end user and operate independently of other call participants. This

means that within one audio or video call you can communicate with multiple participants using various levels of

UC optimizations, or none at all.

Full UC OptimizationFull UC Optimization refers to an optimization method where the audio or video data is sent directly to the

user’s Thin Client, as opposed to over the VDI solution. During a call, a user’s Thin Client records and transmits

audio and video directly to other participants, who in turn send their call data directly to the user’s Thin Client,

bypassing the VDI solution being used. This is a blanket term used solely within this document when discussing

this mode of operation as it is known by numerous names. (e.g., Optimization for Microsoft Teams, Teams for

Virtualized Desktop Infrastructure, Zoom Meetings Optimization for VDI, etc.)

Partial UC OptimizationPartial UC Optimization involves capturing video from a Thin Client by the VDI client, encoding it lightly, and

sending it to the VDI managed computer for access by the UC application through a virtual video input device.

This is a non-industry standard term that will be used within this document while discussing this operational

mode that is known by multiple, vendor specic names.

USB webcam redirectionUSB webcam redirection is an operating mode that uses a feature present in almost all VDI solutions called

USB Redirection to virtually connect the webcam to the remote computer operating system managed by the

VDI solution as if it were directly attached. The webcam is not available to the local Thin Client’s OS in this mode

and the remote computer must have drivers installed for the webcam. When conguring this mode within HP’s

ThinPro operating system you will see this abbreviated as USBR.

Technical Whitepaper | Optimizing video conferencing experiences in VDI with HP Thin Clients

Benets of UC Optimizations in VDI

The main advantage of using full UC optimizations in a VDI solution is better call quality. This is because the

endpoint device, rather than the VDI resource, handles all call data, including voice and video calls to reduce

latency and make calls feel more like an in-person conversation. In addition to improving call quality, UC

offloading has the added benet of reducing compute and bandwidth usage and, in turn, cost of the virtualization

environment hosting if your VDI solution is hosted in a public cloud. The two scenarios below illustrate how

resource consumption when not using full UC optimizations in a private cloud hosted VDI solution can be a

problematic.

Example Scenario 1Example Scenario 1

Consider a small business with 50 employees with a simplied VDI infrastructure consisting of a single server

that is congured to support all 50 users performing typical ofce tasks including email, web browsing, and

creation of documents, spreadsheets, and presentations. These productivity apps typically consume 0.5% of

the available CPU resources on the host server, per user. When a user makes a video call to a vendor, their call

consumes an additional 2.0% of the available CPU resources of the host server. In this example, the total CPU

utilization of the server’s CPU is calculated by the below formula:

(Total # of logged in users ** Average Server CPU utilization per User) ++ (Total # of logged in users in video calls **

Additional CPU Utilization of UC call) == Total Server CPU Utilization

(50 * 0.5%) + (1 * 2%) = 27%

In this scenario, the extra CPU usage introduced is not an issue and there is no impact to the user placing the call

or other users of the VDI implementation who are logged in performing their normal job duties.

Example Scenario 2Example Scenario 2

For this scenario, consider the same small business with all the same parameters as scenario #1, but now 48 out

of 50 employees participate in an all-employee video conference call. The remaining 2 employees do not need to

attend the meeting, but they are actively logged into the VDI solution. In this example the total CPU utilization of

the server’s CPU changes to the below formula:

(Total # of logged in users ** Average Server CPU utilization per User) ++ (Total # of logged in users in video calls **

Additional CPU Utilization of UC call) == Total Server CPU Utilization

(50 * 0.5%) + (48 * 2%) = 121%

The total CPU utilization in this scenario is now 121%, 21% above the CPU’s limit. As a result of the excess need for

CPU resources, the VDI environment in this scenario will begin to slow down and most likely become unusable for

all users, even those not participating in the all-employee conference call.

The table below shows some commonly used VDI solutions with HP Thin Clients and their availability to utilize

full UC optimizations. However, not all HP thin clients are compatible with full UC optimizations as the feature

requires the use of the Thin Client’s computing power. For Thin Client hardware suggestions please refer to the

table provided towards the end of this document.

UC Operating Modes in VDI Solutions

In this section, we will provide an overview of the different levels of UC optimizations and their strengths and

weaknesses. The goal is to help you choose the mode that offers your customers the best user experience

There are three operating modes we will explore:

1. Full UC Optimization

2. Partial UC Optimization

3. USB Redirection

Full UC Optimization

With full UC offloading, the endpoint device handles all voice and video calls, meaning all audio and webcam

video sent to or received by the UC Optimized user is managed by the endpoint device and never passes through

the VDI resource. The following diagram depicts this data flow in a call between 4 individuals using various

devices.

Technical Whitepaper | Optimizing video conferencing experiences in VDI with HP Thin Clients

Strengths

• Reduced call latency between participants helps to promote a great user experience.

• Reduced hypervisor resource consumption for on-premises VDI solutions.

• Reduced public cloud costs for cloud based VDI solutions.

• Because the call data does not traverse the VDI resource this method consumes the least amount of

bandwidth between the Thin Client and VDI resource.

When operating in a Full UC Optimized mode, the number of “hops” that call data takes is reduced, minimizing

latency and making calls feel a little more like in-person conversations. This also reduces resource consumption

on the hypervisors hosting the VDI solution caused by video encoding and network trafc consumed by voice

and video data that is being sent and received by the UC application. In public cloud congurations, reducing

resource consumption can help lower costs associated with usage of these resources. Although the costs may

not be signicant on a per user basis, they can add up when dealing with a large VDI user base.

Weaknesses

• Not all UC Application features are available when using Full UC Optimizations. Refer to UC application

vendor or VDI solution documentation for a full list of unavailable features.

• Entry-level Thin Clients may not perform as desired for any call that is not limited to audio only.

• Dependent on UC application vendor and/or VDI vendor for feature development.

• In most cases software must be installed on both the VDI resource and thin client.

With full UC offloading, the resource consumption of calls is moved from the VDI solution to the thin client. For

audio calls only, an entry-level thin client may sufce, but for scenarios involving screen sharing, application

sharing, or webcam video, a more powerful thin client will be necessary to handle video encoding. The availability

of this level of UC optimization depends on UC vendors developing software for VDI environments. As this mode

of operation usually requires the installation of additional components, customers should already have or plan to

implement a device management solution for both Thin Clients and VDI resources.

To determine the best user experience with UC optimization enabled, it’s recommended to identify user

workflows for UC usage and test to determine the necessary model of thin client that will meet your needs. Refer

to the section of this document titled “HP Thin Client Device Recommendations for Unied Communications” for

general guidance on matching your feature needs to the right device.

Technical Whitepaper | Optimizing video conferencing experiences in VDI with HP Thin Clients

Partial Optimization

Partial UC optimizations, provided by some VDI solutions, capture webcam video on the Thin Client, lightly

compress it and then transmit it to the VDI resource for use by the UC application. It is important to note that

with this level of UC optimization, the call data must travel through the VDI resource that the user is utilizing to be

further processed by the UC application before being sent out to the other user(s) on the call.

Strengths

• Users can participate in video calls in non-mainstream UC applications that do not support full UC

optimizations.

• Because the call takes place within the VDI resource, all UC features are available for use.

• Uses less bandwidth between the Thin Client and VDI resource than USB redirection.

When operating with partial optimization, your users can participate in video calls when using UC applications

that cannot be congured to operate in a fully optimized mode.

Weaknesses

• Extra latency is added to the call due to the extra hop the voice and video data must traverse.

• Dependent on users having access to a reliable and relatively fast network connection between their Thin

Client and the VDI resource.

• Increased resource consumption of hypervisor resources whether it be on-premises or in a public cloud.

Technical Whitepaper | Optimizing video conferencing experiences in VDI with HP Thin Clients

• Requires VDI solution vendor to develop and integrate the feature.

• The ability to capture webcam video is not guaranteed to work with all UC applications in this mode.

When operating in this mode your users’ call data must travel through the VDI solution, thus adding an extra hop

for the call data. This can introduce extra latency to calls and result in a less than ideal user experience. Call

data traveling through the VDI solution may lead to increased costs, especially for cloud based VDI solutions.

This method of UC optimization consumes more bandwidth between the Thin Client and the VDI resource

and is sensitive to dropped packets. It is not suitable for use by users who are connecting from locations with

potentially unstable network connections. Consult the following table to determine if your desired thin client

conguration supports this method of operation.

USB Webcam Redirection

The last, and generally least desirable, level of UC optimization involves no optimizations whatsoever. When

operating in this mode, the USB camera is redirected to the VDI resource using the USB redirection capabilities

that are provided by the VDI solution. This method of operation requires that drivers for the camera be installed

or available for installation on the VDI resources.

Strengths

• Excellent interoperability between all UC Clients and webcams.

• Enables video calls when full and partial UC optimizations can’t be used.

A USB camera that has been redirected to a VDI resource in this way provides the maximum level of

interoperability between the camera and UC software. If your UC software vendor does not support full UC

optimizations for VDI and your software cannot properly utilize your USB webcam using partial optimizations,

then this mode may work for you. This method of operation should also work well for UC software that is

designed to work only with a limited subset of USB cameras.

Weaknesses

• Device drivers for the webcam must be installed or available for installation in the VDI resource.

• Extra latency is added to the call due to the extra hop the voice and video data must traverse.

• Dependent on users having access to a reliable and fast network connection between their Thin Client and

the VDI resource.

• Increased resource consumption of hypervisor resources whether it be on-premises or in a public cloud.

• Of the three operating modes, this one will generally generate the most trafc.

When operating in this mode your users’ call data must travel through the VDI solution thus adding an extra hop

for the call data. This can introduce extra latency to calls and result in a poor user experience. Call data traveling

through the VDI solution may lead to increased costs, especially for cloud based VDI solutions. Customers need

to know this method of UC optimizations consumes even more bandwidth between the Thin Client and the VDI

resource than partial optimization and is very sensitive to dropped packets. It is not suitable for users who are

connecting from locations where network connectivity can be slow or unstable.

Troubleshooting UC Optimization Issues

General Troubleshooting Steps

Because of the number of interacting components, it can be difcult to troubleshoot UC issues within a VDI

solution. This section will offer suggestions for what to look at when investigating UC optimization issues.

The following infographic will help you identify who to contact should you need to reach out to a vendor for

assistance with resolving UC issues.

Technical Whitepaper | Optimizing video conferencing experiences in VDI with HP Thin Clients

Verifying Active UC Optimization Mode

Because most VDI solutions are designed to fall back to less optimal feature congurations in the event of an

error, it is not always readily apparent what type of UC optimization is in operation at a glance. If you encounter

suboptimal performance of your UC software in a VDI solution, you should use the following methods to rst

determine that the intended level of UC optimization is active before conducting a performance evaluation of the

endpoint.

Quickly Determining if Full UC Optimizations are Operational

This method can be utilized to determine if full UC optimizations are operable and is simple to perform by

anyone. During a video call, or when viewing your video preview, with the application in Windowed mode (i.e.,

not maximized), the user moves the call window around the screen. If full UC optimization is operational, there

should be a noticeable “lag” or “jump” with the video portion of the call as it follows the application on the screen.

This effect has been captured in the following screen shot. Notice how both the transmitted and received video

appear to be out of place.

Note: The method outlined above to determine if full UC optimizations are operating is universal and applies to all

UC applications (Zoom, Teams, and Webex) that support this method of operation within a VDI solution.

Investigating Poor UC Performance

If you experience poor performance within any combination of VDI solution and UC application while operating

in a fully optimized mode, the rst diagnostic step should be to monitor CPU consumption on the Thin Client.

Because the Thin Client hosts the call when using UC optimizations, call quality is intrinsically tied to the amount

of available CPU cycles for media encoding, especially when the call includes video. As the CPU usage on the

Thin Client nears 100% during an optimized call, most UC solutions will begin to decrease the resolution of

sent and received video streams along with the video frames per second (FPS). For most UC applications, this

degradation in call quality will begin at approximately 80% CPU. For an optimal user experience, we recommend

that overall CPU usage on a thin client not exceed 70% on average.

If you regularly see CPU usage on a Thin Client exceed 70% during an UC optimized call, there are a few options

available to administrators to attempt to improve performance. A few of the options available are listed below.

• Administratively reduce the resolution and or FPS of video calls and screen sharing sessions to reduce the

computer burden.

• Administratively prevent the use of UC features that consume higher amounts of processing power such as

screen sharing and video calls.

• Adjust VDI solution settings to free up processing power for UC application. As in all UC applications, most

Technical Whitepaper | Optimizing video conferencing experiences in VDI with HP Thin Clients

VDI solutions also have the capability for an administrator to articially limit the quality of connections and

prevent users from utilizing features that may be CPU intensive.

• When necessary, replace Thin Clients that simply do not have enough compute power to handle operating in

a UC optimized mode with more powerful devices.
