You should have: In order to optimize Blast Extreme, it is important to understand two key configurable components: the transport protocol and display protocol codec. If USB redirection is enabled, this traffic uses TCP 32111 between the client and agent. Be certain to test key applications and multimedia content before widespread deployment. Same applications as for the Blast Codec and the H.264 codec. However, compared to other codecs, H.264 requires more processing power to perform its encoding and decoding operations. Explore custom assets and resources for federal, state, and local government framework solutions here, including industry-leading, public-sector solutions for endpoint management security, virtualization, cloud, and mobile, commercial requirements, industry standards, government certification, and accreditation programs. Visit these other VMware sites for additional resources and content. Blast Multimedia Deliver rich video playback for Flash, HTML5, QuickTime, Microsoft Silverlight and Windows Media to a variety of desktop and mobile endpoints. Applications that require the same quality as H.264 with less bandwidth utilization or that require higher quality with similar bandwidth utilization as H.264. Added recommendations for supporting work-at-home and home-office-to-cloud use cases. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). VMware Blast Extreme uses VMware client-side components, installed with VMware Horizon Client, as well as agent-side components, installed on virtual desktops, physical desktops, and RDSH servers that host published applications and desktops. 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. Adjustable Encoder Image Cache Size and Decoder Image Cache Size settings. and includes optimization templates for both Windows desktop and server operating systems. Update for VMware Horizon 7 versions 7.1 and 7.2. Easily manage VM Profile settings across images. Blast Extreme uses the latest security algorithms, including SHA-256. EncoderBlastCodecEnabled Enables or turns off the Blast Codec. JPG/PNG can also be configured to use build-to-lossless mode. Blast Extreme is a next-generation display protocol, developed by VMware. Be certain to test key applications and multimedia content before widespread deployment. Deselect all other codecs and codec options. Various components of a display protocol can be configured to address the different types of screen content and differing network speeds that end users are likely to encounter. The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). To observe this in action we can control the codec selection using the VMware Blast settings on the Horizon client. TLS version and encryption defaults are routinely updated to reflect current best practices. 3 enable file download only, 0 turned off in both directions If UDP is not enabled or is blocked, the initial TCP connection (Step 3) is used instead. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. Figure 4: Horizon Performance Tracker Reports Details of a Blast Extreme Session, NVIDIA Encoded H.264 with High Color Accuracy. Readers should also have a solid understanding of desktop and application virtualization, as well as a good working knowledge of networking and supporting infrastructure, covering topics such as Active Directory, Group Policy, and supporting technologies. FIPS-ready libraries are available for Unified Access Gateway 2.9 or later appliances. If multimedia redirection (MMR) is enabled, this traffic uses TCP port 9427 between the client and agent. HEVC is also known as H.265 and is the industry successor to H.264. SwitchEnc: 1 Screen 1 switching to h264 4:2:0 encoder. This means the client resorts to CPU decoding, which can result in degraded performance on weak client hardware, particularly when using high-resolution monitors. The goal is to configure QoS to prioritize Blast Extreme above general network traffic, but below the few applications that are even more sensitive to delay. Here you can create an account, or login with your existing Customer Connect / Partner Connect / Customer Connect ID. Explore how VMware can help solve an IT team's most pressing digital workspace challenges. 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. The Horizon Performance Tracker does not currently display the codec currently being used per screen by the encoder switch. With zero attack surface, unpublished API, and encrypted data Wyse ThinOS is virus and malware resistant. Running traditionally full-screen applications in a window instead of full-screen can also slash bandwidth utilization. Introduced in Horizon 8 (2106): Enable support for High Dynamic Range (HDR) color. For external connections, Blast Extreme can use the security certificate on the Unified Access Gateway appliance. You are about to be redirected to the central VMware login page. EncoderH264YUV444 Enables or turns off support for High Color Accuracy for H.264. 2 enable file upload only Find assets to help you develop an adoption strategy that engages employees through careful messaging, education, and promotion. It is therefore with great pleasure that we are able to bring you Real-Time Audio-Video functionality. A TCP WebSocket connection is made from the client to the Blast Secure Gateway on port 8443, and then from the Blast Secure Gateway to the virtual desktop or RDSH server on port 22443. If the primary use-case is full motion video or high-speed motion graphics such as gaming, use the H.264, H.264 with High Color Accuracy or High Efficiency Video Coding (codecs), offloaded to an NVIDIA Tesla or newer GPU. General settings include proxy options, time zone forwarding, multimedia acceleration, and other display settings. VMware made the DPI setting on the client device leading and adjusts the remote desktop accordingly. The fewer packets the display protocol puts on the network, the fewer that will be affected by packet loss. (the lowest currently supported setting). Let us help you become the hero of your department. More information about the admin settings is provided in the next section of this chapter. For VMware Horizon HTML Access, this feature is supported on Chrome browsers (version 45 or later) if the device supports H.264 decoding. Each setting is a string value (REG_SZ). Another important aspect to consider is the size of the monitor (or monitors) to be used, and their screen resolutions. NVIDIA, including GTX 10xx and 20xx series models, AMD, including Radeon RX and Vega RX models, Intel, including Intel HD Graphics 530, UHD Graphics 620, and Iris Plus Graphics 650. The connection travels from the client to a Unified Access Gateway virtual appliance on TCP port 443, and then from the Unified Access Gateway to the Connection Server on TCP port 443. However, it does increase client CPU utilization by up to 200 percent for the duration of the redirection (from an average of 8 to 24 percent on a sample test system). Information on how to enable the new Blast Codec is covered in the next chapter, How to Configure Blast Extreme. For more information see Configuring HTML5 Multimedia Redirectionin Configuring Remote Desktop Features in Horizon 7. The table in each section outlines the settings configured by the application template. The traffic uses the native port for each of the remote experience features between the Connection Server and the agent: With an external connection, the client is connecting from outside the corporate network to the Unified Access Gateway. Figure 2: Internal Connection from Client to Agent Using Blast Extreme. WANs typically have just a fraction of the bandwidth that is available on local area networks (LANs). There is something for every experience level. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead. Increase virtual desktop resources. High Efficiency Video Coding (HEVC). In systems with multiple monitors, the encoder switch will use the best codec for each screen. MainApp::OnEncoderConfigChanged: Encoder config changed: EncoderBuildToPNG = 1. The Horizon Performance Tracker does not currently indicate HCA mode when NVIDIA encoding is used. VMware Blast Extreme uses the H.264 video encoding standard which any modern mobile device can handle in its GPU, rather than CPU. HEVC also requires a client device capable of HEVC GPU decoding. By default, the traffic is then side-channeled on the Blast Extreme channel to the agent. Same applications that are ideal for H.264 with HCA while offloading the encoding from the ESXi host CPUs to an NVIDIA GPU. The settings allow you to manage the maximum bandwidth that any one user can consume. This means that some of the original image data is discarded (lost) as part of the compression process. On the right, switch to the tab named Security Servers. This capability not only provides a better user experience but also reduces the resources required for display protocol encoding overall. Added guidance on the benefits of HTML5 multimedia redirection. 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. Introduced in Horizon 8 (2111) is the ability to adjust the size of the Blast codec cache. 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). The fourth Blast Extreme codec option is HEVC. Note: For more information about tunneled connections, see Network Ports in VMware Horizon. For details about the remote experience features, see Configuring Remote Desktop Features, in the guide Configuring Remote Desktop Features in VMware Horizon. Activity Paths are guided and curated learning paths through modules and activities that help you cover the most content in the shortest amount of time.

The registry location to configure Blast Extreme is: HKEY_LOCAL_MACHINE\SOFTWARE\Vmware, Inc.\Vmware Blast\Config. HEVC also requires clients to have physical GPUs with H.265 decode support, but fortunately, as with H.264, most client devices manufactured since 2015 have them. UdpEnabled Enables or turns off support for the UDP transport protocol. These settings apply to HTML Access and all Horizon Client platforms. TCP port 9427 is then used from the Unified Access Gateway to the agent. The following table details the requirements for each codec. The running codec and codec options can also be identified by examining the latest entries in the Blast-Worker-SessionId<#>.log file, as detailed in the following table. In this file, add the single line: RemoteDisplay.allowClientBlastCodec = TRUE. VNCRegionEncoder_Create: region encoder adaptive. The author wishes to thank the following people for their contributions to this paper and the growing knowledge of how to optimize VMware Blast Extreme: To comment on this paper, contact VMware End-User-Computing Technical Marketing at euc_tech_content_feedback@vmware.com. General Settings The following table describes the general settings in the Horizon Client Configuration ADMX template file. The App Volume Manager is a console for managing configuration, creation of AppStacks, and assignment of AppStacks and writable volumes. 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 Connection Server returns the connection information for the virtual desktop or RDSH server to the client. Applications and use-cases that require higher quality typically have demanding graphical requirements that can only be supported by hardware GPUs. compression format. USB redirection traffic can also be side-channeled in the Blast Extreme port. Watch conversations with VMware experts on top-of-mind issues. Yes: Select Allow High Efficiency Video Coding and Allow High Dynamic Range Decoding (HDR). Chris Halstead co-authored the original version of this white paper. Use our product forums to engage with the community. This means the encoder preserves all of the information related to color instead of sacrificing some to increase codec efficiency. One of his key roles as Senior Product Line Manager on the VMware Desktop Product Management team is leading the effort to benchmark and develop comprehensive guidance for VMware Blast Extreme. Increasing this setting helps improve display quality at the expense of higher bandwidth utilization. By Peter Brown, Senior R&D Manager, and Tarique Chowdhury, Software Engineer For information about what's new with Horizon Real-Time Audio-Video, read this 2023 blog. Same applications as for the JPG/PNG codec and the H.264 codec. SwitchEnc: 1 Screen 2 switching to adaptive encoder. JpegQualityHigh The highest quality that JPG/PNG will achieve. However, it does increase client CPU utilization by up to 200 percent for the duration of the redirection (from an average of 8 to 24 percent on a sample test system). While typically supporting just a single user, most households do not yet have LAN-speed Internet connections (gigabit Ethernet). Ability to use either the TCP or the UDP network transport. Even when there might be sufficient bandwidth, such as for a home-based user with a high-speed cable network connection, be certain to validate end-to-end bandwidth, latency, and packet loss before deciding if the use case can be supported. Access technical, third-party tips, tricks, and how-tos. The Blast Codec was designed to be the ideal codec for these types of applications. For lossless support, enable Build-to-Lossless (EncoderBuildToPNG = 1). Added information about OpenGL and DirectX compatibility with hardware GPUs in remoted physical PCs. To provide secure access from external locations and over the Internet, VMware Unified Access Gateway is deployed to provide secure edge services. Computer Configuration -> Policies -> Administrative Templates -> VMware Blast -> Max Frame Rate. Update for VMware Horizon 7 version 7.10. 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. HEVC with High Dynamic Range (HDR) Encoding. RDP is working fine but not pcoip/blast because you might have not optimized these two protocols for this purpose.Increase video memory to 128MB on master image and recompose/push. Deselect all other codecs and codec options. Except under unique conditions, it is not possible to increase quality while limiting system resources. These settings apply to HTML Access and all Horizon Client platforms. VNCRegionEncoder_Create: region encoder switch. Our Communities feature the top Digital Workspace Experts across the world and 3rd-party content. 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. Contains entries that tell you whether JPG/PNG or the H.264 coded is being used. also impact all services, including audio and file transfer, while. The display protocol is transferring 6 frames per second, and estimates of network bandwidth and latency are provided. Follow these guidelines: Note that while the optimizations in this section are typically used with WANs, they can also be used on the LAN if Blast Extremes default settings use more bandwidth or other resources than desired. The VMware Blast ADMX template file ( vdm_blast.admx) contains policy settings for the VMware Blast display protocol. If possible, prevent or encourage only limited use of bandwidth-intensive services such as file transfer. Windows desktop and server operating systems are not designed for efficient virtualization. Figure 2: Codec Options Available in the Horizon Client. Look for Desktop & End-User Computing and under this category, select Download Product under VMware Horizon. Tuning to handle high latency starts with reducing bandwidth. Screen 0/1 @ Resolution: 3840 x 2160. HCA turns off 4:2:0 chroma subsampling, providing a 4:4:4 sample rate instead. If i look into the Settings of the vmware microphone, i can just choose between 8000 Hz and 16000 Hz (default is 8000Hz). With an internal tunneled connection, the client, the server, and the virtual desktop or RDSH server are all also inside the corporate network, but the clients might be on a different subnet from that of the virtual desktops or RDSH servers (where the agent is installed), and you do not want to open ports between the clients and agents directly. Deselect all other codecs and codec options. 1 In VMware Horizon, when using PCoIP Secure Gateway on the Connection Server or Security Server. Contains entries that tell you whether UDP or TCP is being used. However, some applications and use cases require higher quality. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. ) Use Network QoS (Quality of Service). Moving to the cloud? 1 enabled in both directions Blast Unity Touch Easily browse, search and open Windows applications and files from mobile devices with intuitive tools, easier navigation and search bar providing quick access to files. Because H.264 also provides good support for most Windows, Linux, and macOS applications, it is also the default Blast Extreme codec option. This configuration is ideal for digital photography, design, and video production but requires an NVIDIA hardware GPU to support HEVC. VMware recommends using VMware Dynamic Environment Manager (formerly known as User Environment Manager). Log File Locations for Client and Agent Components On the VM registry I configured the following GPO values: In addition, I also tried to manually configure this registry setting: Configuring the Client Clipboard Memory Size (value of 8192 decimal) [despite the fact that is was configured in the above GPO When viewing the Blast logs on the VM I see the following entry: Blast-Worker-SessionId1.log It is especially good at reproducing intricate fonts and other screen content with fine details, including still images and low-motion 3D modeling used by design and engineering applications.
