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).
