The following tuning options are recommended to increase display protocol quality for all use cases and applications. Updated product documentation links to use Horizon 8 documentation. For external connections: Unified Access Gateway 2.9 or later. Figure 2: Internal Connection from Client to Agent Using Blast Extreme. 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. This can result in H.264 being used for one display and JPG/PNG or the Blast Codec being used for another simultaneously. : NVIDIA GPUs will also offload H.264 and HEVC encoding. Another important aspect to consider is the size of the monitor (or monitors) to be used, and their screen resolutions. Optimize the Windows operating system in virtual desktops and RDSH servers using the VMware Operating System Optimization Tool, but recognize that some optimizations applied by default might reduce quality or turn off features required to support higher-quality applications. These settings determine a virtual webcam's maximum frame rate and image resolution. The Blast Codec should be evaluated for use whenever network bandwidth or display protocol CPU utilization is a primary concern. 1. Welcome to VMware Digital Workspace Tech Zone, your fastest path to understanding, evaluating, and deploying VMware End User Computing products. These settings are used to configure the address at which clients can reach the specific server when tunneling is in use. , which uniformly limits the bandwidth of all Blast Extreme services, can also be used to support more difficult network conditions. Yes: Select Allow High Efficiency Video Coding. In testing this has been shown to decrease the amount of network bandwidth used by Blast Extreme. There are several ways that these settings can be applied. HEVC provides up to 50 percent better compression with the same quality as H.264 and can also provide higher quality at similar compression ratios as H.264. A stated goal in the VMware Horizon documentation is "to provide an excellent out-of-the-box configuration for most local area network (LAN) use cases, negating the need to perform complex tuning or learn hundreds of policy settings." VMware notes that "some use cases and situations require additional tuning, especially for wide area networks . If Sound Card is not available in the Settings pane, click Add Device > Sound Card, then click Add. VMware Blast Extreme now supports four codecs: JPG/PNG, H.264, High Efficiency Video Coding (HEVC), and the new Blast Codec. Fortunately, VMware has developed a free tool to optimize Windows desktops and servers. SwitchEnc: 1 Screen 2 switching to adaptive encoder. The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). Although Blast Extreme has been able to provide a functional desktop and application experience when packet loss is in excess of 20 percent, it is with noticeable degradation to user experience. You are about to be redirected to the central VMware login page. Blast Extreme was carefully designed to provide an excellent out-of-the-box experience, with no additional configuration required in almost all cases. Since first joining VMware in 2008, Mark has focused on helping customers succeed with their end-user computing endeavors. General settings include both Computer Configuration and User Configuration settings. The following table documents the key codec and transport settings. I'm sure this feature looked awesome on paper. Encoder Switch: Blast Codec and H.264 with HCA. By default, the traffic is then side-channeled on the Blast Extreme channel to the agent. VMware has built a set of tools and resources to support you and your team as you build out an adoption strategy. Ensure that ESXi hosts have sufficient resources, especially CPU. There is a unified image quality configuration setting that controls the remoted display image quality level across all Blast encoders. Customize your Workspace ONE and Horizon adoption communications using our templates as a starting point. 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. These were typically not sized to handle organizations rapidly shifting their workforces to work-from-home deployments. If UDP is enabled on the client, the Unified Access Gateway, and the agent (default), the client attempts to make a UDP connection to the agent via the Unified Access Gateway. Before tuning Blast Extreme, it is critical to properly size and optimize the virtual desktops, physical desktops, Microsoft RDSH servers, and supporting infrastructure. The VMware Blast service ( VMBlastS.exe) manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. Reducing network bandwidth is key to enabling support for all adverse network conditions. In testing, UDP has been shown to handle packet loss better than TCP in most situations. By design, Blast Extreme provides an excellent out-of-the-box user experience for typical applications and use cases on LANs. If the Horizon Performance Tracker cannot be used or does not provide the desired details, the most effective way to verify the Blast Extreme configuration is to examine the log files on the virtual desktops, physical desktops, or RDSH servers. 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). If you use a Unified Access Gateway virtual appliance for connections from outside the corporate network, by default the connection uses TCP port 8443 and optionally UDP port 8443. Set up the VM with general settings, as follows, and then further configure according to the type of graphics acceleration you are using. Use UDP unless the traffic must pass through a UDP-hostile network device such as a TCP-based SSL VPN. Visit these other VMware sites for additional resources and content. Easily manage VM Profile settings across images. While the JPG algorithm attempts to remove only redundant data, in practice other data is lost as well. This guide is intended for IT administrators and implementors who want to provide end users with the best possible remote display experience. This capability not only provides a better user experience but also reduces the resources required for display protocol encoding overall. We have many more paths than are shown here. In the client VMware Blast settings, Allow High Efficiency Video Decoding (HEVC) and Allow High Dynamic Range Decoding (HDR) needs to be turned on. Then check with the "VMware Horizon Performance Tracker . VMware Blast Extreme Display Protocol in VMware Horizon For more information, see Configuring HTML5 Multimedia Redirection in Configuring Remote Desktop Features in Horizon 7. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). VMware has built a set of tools and resources to support you and your team as you build out an adoption strategy. Except in unique situations, optimizing quality increases bandwidth utilization, whereas optimizations for WANs require limiting quality to function over poor network conditions. . In the following screenshot, the Horizon Performance Tracker is reporting that the Blast session is using UDP and the NVIDIA HEVC codec. Set, Turn off audio unless absolutely required. General Settings The following table describes the general settings in the Horizon Client Configuration ADMX template file. Other codec options can only be enabled by administrators and also require a corresponding Horizon Client setting. VMware Blast Policy Settings It also causes some screen content to letterbox, which may impair user experience. PixelProviderHDRReferenceWhite - Introduced in Horizon 8 (2106). EncoderNvidiaH264Enabled Enables or turns off support for offloading H.264 encoding to NVIDIA GPUs installed in the ESXi hosts. (Requires NVIDIA GPU), VNCRegionEncoder_Create: region encoder NVIDIA NvEnc HEVC. Note: For more information about external client connections, see Network Ports in VMware Horizon.

If bandwidth needs to be limited, start with the. See. HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. Become a desktop virtualization hero with our curated activity path. 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. Yes: Select Allow H.264 Decoding. These settings apply to HTML Access and all Horizon Client platforms. (maximum display bandwidth) to the maximum desired bandwidth utilization per user. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. The VMware virtual desktop pool setting in the Horizon administrative console You'll need to set the video resolution and the monitor account to their maximum values. This section details the workflow of connections that are made so that Blast Extreme can provide the best remote display experience, regardless of whether the user is inside or outside of the corporate network.
