While the JPG algorithm attempts to remove only redundant data, in practice other data is lost as well. This means that some of the original image data is discarded (lost) as part of the compression process. These formats employ compression to reduce the size of the content before it is transferred across the network.

JPG/PNGĪs its name implies, the JPG/PNG codec leverages two image formats, JPG and PNG, to encode and decode display content. Blast Extreme now supports four codecs: JPG/PNG, H.264, High Efficiency Video Coding (HEVC), and the new Blast Codec. The second key configurable component is the codec used to encode and decode the screen content transferred by Blast Extreme. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead.

If WAN circuits are experiencing very high latency (250 milliseconds and greater)įor all other network conditions, VMware recommends that you use UDP for the best user experience.

When traffic must pass through a UDP-hostile network service or device such as a TCP-based SSL VPN, which re-packages UDP in TCP packets.

For the following conditions, VMware recommends that you use TCP rather than UDP: Display protocols have similar performance characteristics.īecause of its efficiency and excellent performance, UDP, which is the default transport protocol Blast Extreme uses, should not be changed, with two exceptions. Streaming video, for example, may freeze for a moment or pixelate briefly, but otherwise continue playing.

UDP does not employ such controls and is therefore well suited for applications like streaming video and online gaming, which need to efficiently send large amounts of data to the client but can tolerate occasional errors.

Although this strategy makes for reliable delivery, the process adds overhead.

TCP, the most common transport protocol on the Internet, has built-in data integrity checking and control to ensure that packets arrive at their intended destination without errors.

In order to optimize Blast Extreme, it is important to understand two key configurable components: the transport protocol and display protocol codec.īlast 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).
