Most video streams through a corporate network are using the Real Time Messaging Protocol (RTMP). The key thing to know about RTMP is that it is different from Hypertext Transport Protocol (HTTP), the common protocol that is used to deliver Web content to your browser. In other words, a lot of video in your enterprise streams using a protocol that is not like the one that the vast majority of content in your network is using to get moved around.
Why does this matter? Chances are, if you work in a large enterprise, your network has all kinds of devices and infrastructure to speed up and optimize the flow of information traveling with HTTP. You will have all manner of caching devices, WAN accelerators, and so forth, to enable rapid and efficient transport of HTTP data all over the globe. Can RTMP video take advantage of that infrastructure? It will be tough.
For this reason, if you can enable HTTP video streaming in your enterprise, you can power better delivery of video across your network. This mostly applies to video on demand (VOD). When users in your enterprise need to access VOD material, if it can stream with HTTP, the video content can be cached and optimized all over the place. This could be more beneficial than other video streaming mediums.
