Citrix SD-WAN WANOP

Video caching scenarios

You can deploy video caching on Citrix SD-WAN WANOP appliance under the following scenarios:

Branch office access

In this use case, users access the Internet through the web browsers on their computers. Those requests that involve video content from an enabled site, such as Vimeo, are cached on the local Citrix SD-WAN WANOP appliance. Any subsequent access of the same video results in cache hits on the local appliance, allowing the video to be delivered at LAN speed and without waiting for the remote server.

Unlike other Citrix SD-WAN WANOP features, which accelerate traffic between paired devices, this feature is a single-ended operation that requires only the local appliance, with access to the video website.

Branch office with Citrix Virtual Apps and Desktops users using HDX MediaStream flash redirection

HDX flash redirection is a feature of Citrix Virtual Apps and Desktops. Instead of rendering the video on the remote Virtual Desktops display by using the server-side or datacenter Internet, flash videos are tunneled to the local system through this feature. The video is streamed to the actual client machine and is rendered on the actual client, using the branch office Internet. Enabling the video caching feature on the branch-side Citrix SD-WAN WANOP appliance can give users a significantly improved viewing experience. Additionally, enabling the feature reduces the bandwidth requirement for streaming videos.

Enterprise HTTP video web server

In this use case, users access the video web servers from the datacenter. When you enable the video caching feature on the branch-side Citrix SD-WAN WANOP appliance, the user request is served from cache of the branch-side Citrix SD-WAN WANOP appliance. This helps reduce network traffic to the datacenter Citrix SD-WAN WANOP appliance. As a result, the bandwidth of the datacenter Citrix SD-WAN WANOP appliance can be used to serve traffic for other branches.
