Suggested Top 10 for 2016
This is numbered 1 through 10 but in reality is in no particular order!

1. E-mail discovery for Citrix Receiver using DNS SRV records – http://docs.citrix.com/en-us/receiver/windows/4-3/receiver-windows-install-wrapper/receiver-windows-cfg-command-line-42.html internally and externally on the Gateway – http://docs.citrix.com/en-us/netscaler-gateway/10-1/ng-xa-xd-integration-edocs-landing/ng-clg-integration-wrapper-con/ng-clg-session-policies-overview-con/ng-clg-storefront-policies-con/ng-clg-storefront-email-discovery-tsk.html.
2. Implement SplitDNS or more technically correct “split-horizon DNS” – https://en.m.wikipedia.org/wiki/Split-horizon_DNS my favourite personally over email based discovery :-)!
3. Brand your NetScalers (Unified) Gateway – http://docs.citrix.com/en-us/netscaler-gateway/11-1/vpn-user-config/custom-portal.html and App Store (StoreFront) – http://docs.citrix.com/en-us/storefront/3-7/manage-citrix-receiver-for-web-site/unified-receiver-experience.html to match and keep it clear, clean and simple!

4. Implement HDX Adaptive Display v2 available in 7.11+ – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/policies/reference/ica-policy-settings/graphics-policy-settings.html as your default Graphics Mode and if you can’t then Thinwire Compatible Mode – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/hdx/thinwire.html.

5. If using Skype for Business 2015 or 2016 implement the HDX RealTime Optimisation Pack 2.x.n http://docs.citrix.com/en-us/hdx-optimization/2-1/hdx-realtime-optimization-pack-overview.html to offload the video/audio to the local end-points (Windows, Mac and Linux) saving on backend compute and density loss for XenApp.*

6. Implement domain pass-through for internal users – http://docs.citrix.com/en-us/storefront/3-7/plan/user-authentication.html.
7. Deploy the (latest) HTML5 Receiver for remote access – http://docs.citrix.com/en-us/receiver/html5/2-2/user-experience.html.

8. When using Citrix Receiver for Windows (with HDX engine 14.4), the GPU can be used for H.264 decoding wherever it is available at the client – http://docs.citrix.com/en-us/receiver/windows/4-5/improve.html.
9. Deploy Self-Service Password Reset (SSPR) – http://docs.citrix.com/en-us/self-service-password-reset/1-0.html.

10. The most difficult to justify probably re the cost(s) but assigning a low end vGPU GRID profile or utilising the Intel Iris Pro Graphics with XenServer 7 to provide enough/suitable GPU capacity to all virtual apps & desktops (oldISH and modern) provides a much better experience so setup a PoC to see and try if for yourself and finally NVidia now supports H.264 offloading onto there GRID Cards in 7.11 🙂 – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/whats-new.html#par_anchortitle_59c9.

Introduction
The following capability is also referred to as Selective use of H.264, Selective H.264, HDX Adaptive Display v2 and Hybrid mode – https://www.citrix.com/blogs/2016/09/28/hdx-graphics-gone-hybrid/ but in this blog post it’s referred to as “HDX Adaptive Display v2” but its technical accurate name from eDoc’s is “Selective use of a video codec (H.264) to compress graphics” as reffered to here – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/whats-new.html#par_anchortitle_59c9.

Overview
In the release of XAD 7.11 (Seven11) a new Thinwire HDX policy was released which is part of the following policy Use video codec for compression” with the following option selected “For actively changing regions” which enables HDX Adaptive Display v2 – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/whats-kmnew.html#par_anchortitle_59c9 which blends the following Citrix HDX Graphics modes H.264 & Thinwire Compatible Mode together to offer the best UX but also to provide a balanced apporach by implementing the most right vs. relevant HDX graphics mode to offer the best rich & HD experience or near to local-like experience while balancing all compute, network resources between the server and or desktop VDA over the organisational network, internet to the users end-point.

The following CTX blog article – https://www.citrix.com/blogs/2016/09/28/lossless-compression-lowering-the-cost-of-pixel-perfection/ most accurately describes the what, the how and the why? So be sure read it and watch the following YouTube video demonstration entitled “Citrix Desktop Master Class – Adaptive Display v2 Demo by Lee Bushen“.

Understanding Actively Changing Regions
If you take a look at the below example of a YouTube web page (rendered in HTML in Oct 2016) e.g delivered as a virtual app published internet browser or a virtual desktop and you access the above YouTube web page HDX Adaptive Display v2 will selectively utilise H.264, Thinwire and overlay lossless text.

To further understand this in greater details please refer to this Citrix blog article first and foremost https://www.citrix.com/blogs/2016/09/28/lossless-compression-lowering-the-cost-of-pixel-perfection/ and then watch

My Own View/Opinion
ThinWire Compatible Mode can be implemented to replace the Citrix SuperCodec (H.264) in my personal opinion for numerous use cases hOwEvEr based upon your organisations end-user use cases and or scenario’s by department and role you should always test which graphics mode/encoder(s) are most suitable within your environment by department or role to meet your end-user’s X1 UX expectations on a daily basis.

What is Thinwire Compatible Mode?
If your new to Citrix I’d suggest that before reading any further to get a better understanding of what Thinwire Compatible Mode (TCM) is and does i’d suggest that you read the following entitled “HDX technologies for optimizing application and desktop delivery” available at – http://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/citrix-hdx-technologies.pdf. Its the latest graphics encoder/mode available within Citrix XAD 7.6 FP3 supported on the following OSes Windows 8.x, 10 and Windows Server 2012 R2.

Use Cases for TCM
1. Lower powered endpoint devices that can support Receiver but do not support Citrix’s SuperCodec which requires an H.264 decoder
2. Delivery of virtual apps and desktops over low bandwidth networks e.g remote branch offices that have limited internet uplink capacity based upon there geographic location i.e. ISDN, 3/4G or low capacity ADSL.
3. Delivery of 3D apps over LAN networks offers a great X1 UX which a fuzzy-first approach as described at – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-6/xad-hdx-landing/thinwire-compatibility-mode.html search for “Build to lossless” on that web page. You should always thoroughly test between both TCM/H.264 graphics modes to ensure that your end-users X1 UX meets there expectations and requirements day to day.
4: Greater user density on Windows Server 2012 R2 for XenApp based workloads.

TCM Key Features
The following is just a short snippet into some of the features part of TCM below so be sure to check out and read the following CTX Blog article –
https://www.citrix.com/blogs/2015/10/09/a-big-leap-in-ica-protocol-innovation-for-citrix/ for a full list of all the details and more.

– Intelligent bitmap matching for a bitmap-only provider. As much as possible, previously sent bitmaps are reused resulting in lower bandwidth.
– Emulated 16-bit mode, further reducing bandwidth for typical workloads.
– Ultra-low server CPU usage, improving scalability.
– Designed for port to Linux (already used by the Citrix Linux VDA)
– …

Demonstration of Thinwire Compatible Mode
TBC…

Pre-requisites & System Requirements for Deploying a Basic/Intro Thinwire Compatible Mode policy (Draft + The Basic’s Only)
1: Download and install the latest component’s for XAD 7.6 FP3 within a test/poc environment and not in a PROD environment!
2: Currently the XAD 7.6 FP3 VDA’s provide support for TCM with the following Windows OSes Windows 8.x, Windows 10 and Windows Server 2012 R2 OSes.
3: Citrix Receiver You can utilise the latest or older Citrix Receiver’s including the HTML5 Receiver with Thinwire Compatible Mode encoder.
4: Create the following policy in Studio below to enable TCM within a ICA/HDX session:

– Create a new policy
– Search for the following policy entitled “Use video codec for compression” select it and set the following value – “Do not use Video codec” which will force the ICA/HDX session to utilise Thinwire Compatibility Mode.
– Assign the policy to your test “Delivery Group” with either a virtual desktop (Win 8.x, 10 or Server 2012 R2) and save the new policy.
– Login to ReceiverforWeb or Citrix Receiver and launch your virtual desktop ensure that your test user was assigned to the test delivery group which you assigned the TCM policy to/against.

Tuning Thinwire Compatible Mode
You can easily tune TCM to utilise less bandwidth with a single policy entitled “Preferred colour depth for simple graphics” but still delivery a really good eXperience 1st User eXperience for your end-users. Simply modify the TCM policy that your created earlier in this blog article and search for and add “Preferred colour depth for simple graphics” and select either “16 bits per pixel” or “24 bits per pixel” then click next and next again saving the policy. Now disconnect from your existing ICA/HDX session to your test virtual desktop and re-launch it and if you’ve opted for 16 bits per pixel in the policy above you’ll notice a difference straight away BUT the UX is still acceptable graphically for knowledge/task workers and more importantly its still as responsive and usable.

There are obviously many other policies that can be applied to make even more efficiencies so for a full list including detailed notes of what to configure please refer to and check out the following CTX article entitled “HDX Graphics Modes – Which Policies Apply to DCR/Thinwire/H.264 – An Overview for XenDesktop/XenApp 7.6 FP3” available at – http://support.citrix.com/article/CTX202687. I have embedded the basics into a simple HTML table below with how to explicitly enable ECM for testing purposes.

Policy Name Default Value Comment
Display memory limit 65536 KB http://support.citrix.com/article/CTX201696 – Support for Monitors Including 4K Resolution and Multi-Monitors
Dynamic window preview Enabled
Extra color compression Disabled Legacy Mode *
Moving image compression Enabled Legacy Mode
Preferred color depth for simple graphics 24 bits per pixel Legacy Mode **
Target frame rate 30 fps Legacy Mode

What is Framehawk?
It forms part of HDX Broadcast technologies within the High Definition eXperience (HDX) stack providing an enhanced X1 UX over broadband wireless, cellular connections where users experience the effects of packet loss, congestion, latency and jitter. The technology came from the Framehawk acquisition made by Citrix in 2014 ref – https://www.citrix.com/news/announcements/jan-2014/citrix-acquires-framehawk.html. Framehawk is defined as light weight frame buffer protocol (UDP based) and adds a new virtual channel to the ICA protocol. The initial release is targeted at users connected to XAD 7.6 FP2 via TRU networks however as of 14/08/2015 ref * Framehawk is now also available for users running the latest up to date iOS Receiver – http://blogs.citrix.com/2015/08/03/receiver-for-ios-6-0-now-available-with-framehawk-support/ utilising NetScaler Gateway 11.0 build 62.10 ref the following CTX blog which also includes details surrounding the initial Framehawk release within XAD 7.6 FP2 at – *http://blogs.citrix.com/2015/06/30/our-first-release-of-framehawk-technologies/.

New Use Cases for Framehawk
The following official Citrix blog articles provides insight into some of the use cases for Framehawk – http://blogs.citrix.com/2015/08/17/new-use-cases-for-framehawk/.

HDX Framehawk Performance in XenApp and XenDesktop 7.6 FP3

Demonstration of Citrix (HDX Broadcast now with Framehawk) vs. VMware

Pre-requisites & System Requirements for Deploying HDX Broadcast now with Framehawk (Draft + The Basic’s Only)
0: The HDX Broadcast now with Framehawk admin guide is available at – http://docs.citrix.com/content/dam/docs/en-us/xenapp-xendesktop/xenapp-xendesktop-7-6/downloads/Framehawk%20Administration%20Guide.pdf which I would strongly suggest that you read through before undertaking any type of PoC or internal testing of Framehawk’s capabilities within your own home lab, organisation demo environment.
1: You need to download the XAD 7.6 FP2 components from http://www.citrix.com/downloads.html. Also download and the firmware update for NetScaler Unified Gateway 11.0 build 62.10** to upgrade your NUG V/A.Note: The current supported Citrix Receivers (update 22/08/2015) are the Windows Receiver 4.3 or iOS Receiver 6.0.
2: Download the DisplayStateGUI.exe * tool from http://blogs.citrix.com/2015/08/17/got-framehawk-weve-got-remote-access-tips-and-tricks/ its a good read by way so be sure to read through that official CTX blog articles aswell prior to deploying Framehawk in your Home/Test lab or for a customer PoC.
3: In your Citrix test or home lab environments snapshot all the relevant XAD 7.6 infrastructure components that requires which an update which is most rior to proceeding. This is typically a common leading best practise so that you revert back in the unlikely event of a failure or corruption of any components during the infrastructure update.
4: Once the updates have been completed successfully installed and you’ve rebooted your compoments seperately in an agreed maintenance window the launch Citrix Studio upon a successful reboot and create a new policy selecting the Framehawk policies and adding them to your test user(s) or group(s). It is not recommended to apply this HDX policy to all users within your Site but only those whom are experiencing high packet loss ref page 12 of the Framehawk Admin Guide. Also be sure to carefully review and understand the provided technical overview of each policy setting by reading the policy description.TIP: Type in frame in the search window to find the Framehawk policies in Studio quicker.
5: Also make sure that your install and update the server, desktop VDA’s within your template images or create a new set of template(s) for your desktop and server OSes. It’s your choice :-).
6: I’d suggest that you utilise a Windows end-point for your initial tests of Framehawk, so navigate to http://receiver.citrix.com which should auto detect your Windows endpoint and recommend that you download and install Citrix Receiver 4.3 for your Windows OS.
7: Once the Windows Citrix Receiver 4.3 has successfully installed and configure Receiver to point to your Citrix test or home lab environment and begin testing :-). TIP: Why not setup a DNS SRV record for e-mail based discovery check out – http://docs.citrix.com/en-us/storefront/3/sf-plan/sf-plan-user-access.html.
8: Once your have configured Receiver a lunch a destkop and run DisplayStateGUI.exe * and also login into the new and update Director to check that your launch ICA/HDX session is in fact utilising using Framehawk and not DRC or the SuperCodec.
9: Once your happy proceed to snapshotting your NUG V/A and begin the firmware upgrade from your exsiting NUG build to the current supported firmware version which is 11.0 build 62.10**.
10: Once your have upgrade your NUG V/A and it is functioning as expected then proceed with the following to enable delivery of HDX Broadcast now with Framehawk via your NetScaler (Unfied) Gateway.
11: Enable DTLS in the settings of the VPN virtual server, enable and open 443 on TCP/UDP and unbind and rebind the SSL cert-key pair this second part is mandatory for more detail ref 16 of the Framehawk admin guide.
12: Deploy XAD 7.6 FP2 as your typically would utilising either the built-in wizards, manually using AppExpert e.t.c
13: Once its is successfully configured navigate to your external gateway FQDN and login to ensure that you can successfully authenticate and access your RfW powered by StoreFront 3.0 with the unified experience enabled ref – http://docs.citrix.com/en-us/storefront/3/sf-manage/sf-receiver.html. Now logout and return to the NUG Admin WebUI.
14: Now complete the following steps within the NUG Web AdminUI to enable and allow Framehawk ICA/HDX sessions through your NetScaler Unified Gateway V/A:

– Click configuration tab -> NS Gateway -> Virtual Servers now click “Edit” then click “More”
– Select to enable DTLS then click “Ok”
– Now within the VPN Server screen click e.g “1 Server Certificate”
– Write down the name of the certificate
– Select your server cert and the click on Unbind above from the list of menu options and then save/close
– You be returned to the VPN Server screen and there will be NO certs that is normal. Now click on “No Server Certificate” to reopen it
– Click on the + sign
– Find your certificate within the list and click “Select” then when prompted click “Bind”.
– Ignore and click OK on the warning error message entitled “No usable ciphers configured on the SSL vserver/serivce

15: Begin testing using Windows Receiver 4.3 from any supported Windows end-point.
16: If you wanted to enable and allow Framehawk access from iOS devices running Receiver 6.0 then please complete the following:

– On your SFS access App_Data dir of your Store in C:\inetpub\wwwroot\Citrix\Store\App_Data\
– Open the file entitled default.ica
– Under the [WFClient] section within the file add the following line of code Framehawk=On which should be under ProxyUseFQDN=Off
– Click “Save”

17: Begin testing using Citrix Receiver iOS 6 on an iOS device.
18: If you have downloaded the initial Framehawk Admin Guide is doesn’t including the remote access setup and configuration so please re-download the admin guide at – http://blogs.citrix.com/2015/08/17/got-framehawk-weve-got-remote-access-tips-and-tricks/. It well worth a re-read in my view to better understand Framehawk.
