If UDP is enabled on the agent (default), the Blast Proxy process (in Horizon Agent) attempts to make a UDP WebSocket connection to the client on port 22443. HEVC will not work with ESXi CPU encoding alone. Keep in mind, however, that Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. The following diagram shows the ports used for an internal tunneled connection, and the list that follows describes the order in which the connections are made. Added recommendations for supporting work-at-home and home-office-to-cloud use cases. Reducing network bandwidth is key to enabling support for all adverse network conditions. More than 8 virtual CPUs might be required to support the most demanding use cases, especially video gaming, even with NVIDIA hardware GPUs. A codec is used to encode and decode the screen content transferred by Blast Extreme. 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. Blast Extreme is a display protocol built by VMware to deliver an immersive, feature-rich experience for end users across devices, locations, media, and network connections. 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.

Note: Requires Horizon Agent 7.11 and Horizon Client 5.3 or later. 3 enabled server to client only. Blast can deliver a decent experience with default settings, however, some networks and scenarios need additional tuning. Offloading the display protocol encoding is enabled by default but can also be turned off if the GPUs must be dedicated to supporting other tasks. With zero attack surface, unpublished API, and encrypted data Wyse ThinOS is virus and malware resistant. EncoderHEVCEnabled Enables or turns off support for the HEVC codec (H.265). It is remarkable that this setup can be made to work over a WAN at all! Before starting to plan or trying to troubleshoot Horizon and Blast connections, it is important to understand how a VMware Horizon Client connects to a resource. . If multimedia redirection (MMR) is enabled, this traffic uses TCP port 9427 between the client and agent. Increase the frame rate. Ensure that ESXi hosts have sufficient resources, especially CPU. Is there a GPO or something? Easily manage VM Profile settings across images. Test the new Blast Codec. By default, H.264 in Blast Extreme uses a 4:2:0 sample rate, with the 2:0 indicating that only a quarter of the information about image color is included, compared to HCAs 4:4:4. Except in unique situations, optimizing quality increases bandwidth utilization, whereas optimizations for WANs require limiting quality to function over poor network conditions. The Blast Extreme template is named: vdm_blast.admx and can be found in the VMware-Horizon-Extras-Bundle-xxx.zip file, with xxx indicating the corresponding version of Horizon. H.264 will provide support for full-motion graphics, whereas the encoder switch will ensure that the most efficient codec is dynamically used for each screen based on screen content.
