Blast Extreme includes the following security features to support Horizon: Display protocols must be able to efficiently provide the best user experience for various types of screen content, including text, still images, streaming video, 3D rendering, and audio. To observe this in action we can control the codec selection using the VMware Blast settings on the Horizon client. Some tradeoff in system configuration, supportable applications, and user experience is to be expected. Streaming video, for example, may freeze for a moment or pixelate briefly, but otherwise continue playing. EncoderH264YUV444 Enables or turns off support for High Color Accuracy for H.264. Explore how VMware can help solve an IT team's most pressing digital workspace challenges. To enable the new feature, you need to set this registry key on your VDI machine: Key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\VMware, Inc.\VMware Blast\Config\EncoderSwitchEnabled. This connection is from the client to UDP port 8443 on the Unified Access Gateway. Become a desktop virtualization hero with our curated activity path. Flexibility with regard to configuration methods, which include using Windows Group Policy or Horizon Smart Policies included with, Option to simplify setup, including opening only one port (TCP 443) on front-end firewalls when, AES (Advanced Encryption Standard) encryption. The Blast Worker process determines whether UDP is enabled on the agent and allowed on the client. : NVIDIA GPUs will also offload H.264 and HEVC encoding. Customize your Workspace ONE and Horizon adoption communications using our templates as a starting point. For information about administrator settings, end-user settings, and various optimization strategies, see the VMware Blast Optimization Guide. Lower power consumption means longer battery life. Update for VMware Horizon 7 versions 7.1 and 7.2. Special note about NVIDIA GPU supported use cases: Using NVIDIA GPUs to support H.264 and High Efficiency Video Coding (HEVC) substantially increases session bandwidth. But when rapidly changing screen content such as streaming video is detected, Blast Extreme automatically switches to multimedia optimized H.264. Horizon Agent 7.5 or later is required; Horizon Agent 7.10 or later is recommended. To provide secure access from external locations and over the Internet, VMware Unified Access Gateway is deployed to provide secure edge services. VMware made the DPI setting on the client device leading and adjusts the remote desktop accordingly. Figure 4: External Connection from Client to Agent Through the Unified Access Gateway. JpegQualityLow The lowest quality JPG/PNG will start with before building the screen to higher quality.

Watch conversations with VMware experts on top-of-mind issues. In this mode, under typical application conditions, Blast Extreme uses the Blast Codec or JPG/PNG codec, both of which are optimized for text and still image quality. These settings will override all other Blast Extreme settings. Blast Extreme supports two transport protocols to carry the display traffic between clients and the Horizon infrastructure: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). See the faces behind the names of our Tech Zone content. Note: Requires Horizon Agent 7.10 and VMware Horizon Client 5.2 or later. Join the community by engaging in forums, events, and our premier community programs. Note that HDR is an optional capability of HEVC (High Efficiency Video Coding, H.265) and requires an NVIDIA hardware GPU. Mark Ewert is a Senior Product Line Manager, EUC Desktop Products, VMware. There are some special considerations when supporting work-from-home and home-office-to-cloud use cases: The other common reason to tune display protocols is to increase quality. Introduced in Horizon 8 (2106) is support for High Dynamic Range (HDR) encoding to provide higher graphical quality with vastly improved color range and contrast. Because WANs involve long-haul circuits or even satellite connections, they also impose latency (delay), extending how long it takes packets to travel from sender to receiver. Many of the codec options and Blast Extreme settings can be controlled by administrators. Since first joining VMware in 2008, Mark has focused on helping customers succeed with their end-user computing endeavors. Note: Despite the presence of a physical GPU, Blast Extreme with physical desktops is not able to offload H.264, H.264 with High Color Accuracy, or High Efficiency Video Coding (HEVC) encoding, even with NVIDIA GPUs. Note: Dynamic Environment Manager also provides optimization templates for Blast Extreme. Value: 1. Install VMware Horizon Client on end users' machines and have end users access their remote desktops and applications. A codec is used to encode and decode the screen content transferred by Blast Extreme. This is typically achieved using a Differentiated Services Code Point (DSCP) marking of AF41. If testing reveals the Blast Codec is not yet able to fully support an application or use case, simply switch to one of the other three codecs for now. One of the easiest methods is to use the Windows Group Policy template provided with each release of VMware Horizon. Fortunately, this processing can be offloaded from the CPU to graphics cards (GPU) in the device. Testing has revealed this reduces desktop and per-user RDSH server CPU utilization by up to 60 percent and per-user session bandwidth by up to 80 percent. EncoderImageCacheSizeKB Introduced in Horizon 8 (2111). Yes: Select Allow H.264 Decoding, and select Allow High Color Accuracy. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported. DecoderImageCacheSizeKB Introduced in Horizon 8 (2111).Set on the client. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported at high screen resolutions without NVIDIA GPUs. Begin your journey leveraging cloud-based services for desktop environments. In testing with a single 4K display, viewing a typical YouTube video in standard windowed mode used 53 percent less bandwidth and 23 percent less virtual desktop CPU than watching the same video full-screen. The settings are configured in the Windows Registry of the Windows virtual and physical desktops and Microsoft RDSH servers. Enable High Color Accuracy (HCA) for H.264 if supporting an H.264 preferred use case that has exhibited display fuzziness, lack of font or image sharpness, or problems with color reproduction. Therefore, Blast Extreme can typically be left using its default setting of UDP unless the traffic must pass through a UDP-hostile network device such as a TCP-based SSL VPN. Ability to meet performance requirements for visually demanding applications when used with NVIDIA Tesla GPUbased hardware acceleration in the host. Accepts integer value greater than 0. If extensive use of graphically intensive content such as streaming video must be supported, consider asking users to view this content in a window, instead of full-screen mode. Blast Extreme supports two transport protocols to carry the display traffic between clients and the Horizon infrastructure: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). Therefore, it is imperative to start by verifying that all components are sized properly and have sufficient resources and available capacity. On the right, switch to the tab named Security Servers. The future successor to JPG/PNG, the Blast Codec provides a high-quality user experience while using significantly less CPU and network bandwidth required by other codecs. Configuring Remote Desktop Features in VMware Horizon, Enabling the USB Over Session Enhancement SDK Feature. EncoderBuildToPNG Enables or turns off build-to-lossless mode for the JPG/PNG codec. The settings allow you to manage the maximum bandwidth that any one user can consume. Visit these other VMware sites for additional resources and content. We also frequently discover that the underlying ESXi hosts are overutilized and are exhibiting clear indicators of problems impacting user experience such as high CPU Ready times. All three howeverNVIDIA, AMD, and Intelare able to support Microsoft DirectX. Optimize the desktops and RDSH servers using the VMware Operating System Optimization Tool. The former option allows Blast Extreme to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. If USB redirection is enabled, this traffic, this traffic uses TCP port 443 from the client to the Horizon Tunnel on the Unified Access Gateway. Note: At this point, the VMware Blast service on the agent side (Horizon Agent on the virtual desktop or RDSH server) proxies the incoming connection. See, Worksheet for Creating an Instant-Clone Desktop Pool, You can also configure the remote display protocol at the RDSH server farm level. Note: This parameter does not impact the bandwidth of other services such as audio and file transfer, which are unrelated to transfer of the screen. Settings made directly in the registry are dynamic and take effect immediately, whereas those requiring a client setting will take effect only after the client disconnects and reconnects to a live session. End-users access to their personalized virtual desktops or remote applications from company laptops, their home PCs, thin client devices, Macs, tablets, or smartphones. Updated product documentation links to use Horizon 8 documentation. Blast Multimedia Deliver rich video playback for Flash, HTML5, QuickTime, Microsoft Silverlight and Windows Media to a variety of desktop and mobile endpoints. However, this example can be achieved by disabling support for the H.264 codecs competing options: JPG/PNG and HEVC. This means the encoder preserves all of the information related to color instead of sacrificing some to increase codec efficiency. VNCEncodeRegionNvEncGetHandle: region encoder NVIDIA NvEnc H264 using YUV 4:2:0 color space. EncoderHEVCEnabled Enables or turns off support for the HEVC codec (H.265). There is something for every experience level. PixelProviderHDRReferenceWhite - Introduced in Horizon 8 (2106). Start here to understand the basics of the award-winning product suite. See Enabling the USB Over Session Enhancement SDK Feature. MaxBandwidthKbpsPerMegaPixelSlope The maximum bandwidth used to transfer screen contents per megapixel remoted, in kilobits per second. By default, they are expected to be installed on dedicated, physical hardware, and not separated from their intended users by networks and display protocols. Be certain to test any QoS configuration extensively to ensure not just proper performance for Blast Extreme, but that the configuration does not negatively impair other applications and services that the network must also support. Blast Codec support for the encoder switch was added in Horizon 7.11. : Many of the optimizations available to the other codecs have not yet been developed for the Blast Codec, including the ability to set custom image qualities. The range is 136, where 1 is the highest quality. NVIDIA Encoded H.264 (H.264 offloaded to GPU), NVIDIA Encoded H.264 (H.264 offloaded to GPU) with HCA. Set up an RDSH server VM and install applications to be remoted to end users. Get all the Tech Zone demos in one place. Welcome to VMware Digital Workspace Tech Zone, your fastest path to understanding, evaluating, and deploying VMware End User Computing products. By default, Blast Extreme is capped at 30 frames per second (FPS). Applications that require higher graphical quality with improved color range and contrast, such as digital photography. HEVC also requires a client device capable of HEVC GPU decoding. This means most should be considered medium- to high-speed WAN use cases. Navigate the sophisticated world of Unified Access Gateway (UAG) for Workspace ONE and Horizon 8. Keep in mind, however, that Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing.
