My Own View\/Opinion<\/strong> What is Thinwire Compatible Mode?<\/strong> Use Cases for TCM<\/strong> TCM Key Features<\/strong> – Intelligent bitmap matching for a bitmap-only provider. As much as possible, previously sent bitmaps are reused resulting in lower bandwidth. Demonstration of Thinwire Compatible Mode<\/strong> Pre-requisites & System Requirements for Deploying a Basic\/Intro<\/i> Thinwire Compatible Mode policy (Draft + The Basic’s Only)<\/i><\/strong> – Create a new policy Tuning Thinwire Compatible Mode<\/strong> 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 \u2013 Which Policies Apply to DCR\/Thinwire\/H.264 \u2013 An Overview for XenDesktop\/XenApp 7.6 FP3<\/i><\/u>” available at – http:\/\/support.citrix.com\/article\/CTX202687<\/a>. I have embedded the basics into a simple HTML table below with how to explicitly enable ECM for testing purposes.<\/p>\n
\nThinWire Compatible Mode can be implemented to replace the Citrix SuperCodec (H.264) in my personal opinion for numerous use cases hOwEvEr<\/i> based upon your organisations end-user use cases and or scenario\u2019s by department and role you should always<\/i> test which graphics mode\/encoder(s) are most suitable within your environment by department or role to meet your end-user\u2019s X1 UX expectations on a daily basis<\/b>.<\/p>\n
\nIf 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<\/i>” available at – http:\/\/www.citrix.com\/content\/dam\/citrix\/en_us\/documents\/products-solutions\/citrix-hdx-technologies.pdf<\/a>. 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.<\/p>\n
\n1. Lower powered endpoint devices that can support Receiver but do not support Citrix’s SuperCodec which requires an H.264 decoder
\n2. 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.
\n3. Delivery of 3D apps over LAN networks offers a great X1 UX which a fuzzy-first approach<\/i> as described at – http:\/\/docs.citrix.com\/en-us\/xenapp-and-xendesktop\/7-6\/xad-hdx-landing\/thinwire-compatibility-mode.html<\/a> 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.
\n4: Greater user density on Windows Server 2012 R2 for XenApp based workloads.<\/p>\n
\nThe 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 –
\nhttps:\/\/www.citrix.com\/blogs\/2015\/10\/09\/a-big-leap-in-ica-protocol-innovation-for-citrix\/<\/a> for a full list of all the details and more.<\/p>\n
\n– Emulated 16-bit mode, further reducing bandwidth for typical workloads.
\n– Ultra-low server CPU usage, improving scalability.
\n– Designed for port to Linux (already used by the Citrix Linux VDA)
\n– …<\/p>\n

\n1: Download and install the latest component’s for XAD 7.6 FP3 within a test\/poc environment and not in a PROD environment!<\/i><\/b>
\n2: 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.
\n3: Citrix Receiver You can utilise the latest or older Citrix Receiver’s including the HTML5 Receiver with Thinwire Compatible Mode encoder.
\n4: Create the following policy in Studio below to enable TCM within a ICA\/HDX session:<\/p>\n
\n– Search for the following policy entitled \u201cUse video codec for compression<\/i>\u201d select it and set the following value – \u201cDo not use Video codec<\/b><\/i>\u201d which will force the ICA\/HDX session to utilise Thinwire Compatibility Mode.
\n– Assign the policy to your test “Delivery Group<\/i>” with either a virtual desktop (Win 8.x, 10 or Server 2012 R2) and save the new policy.
\n– 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.<\/p>\n
\nYou can easily tune TCM to utilise less bandwidth with a single policy entitled “Preferred colour depth for simple graphics<\/i>” 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<\/i>” and select either “16<\/u> bits per pixel<\/b><\/i>” or “24<\/u> bits per pixel<\/b><\/i>” 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<\/i> the UX is still acceptable graphically for knowledge\/task workers and more importantly its still as responsive and usable. <\/p>\n
