Existing users upgrading to EchoSystem 5.5 or any of the 5.5 Service Packs, and who are using an Internal configuration of Wowza can continue to do so; the ESS will work with the existing Wowza v3.5, and will update the necessary items on upgrade. However, if you want to upgrade to Wowza 4, you must change to an External Configuration of Wowza. Upgrading to Wowza 4 and converting to an External Wowza media server configuration are both strongly recommended.

- When serving on-demand content, the server needs to move data from the storage disk to the streaming server to the student computer. But this data transfer does not have to happen in real time. The audio, video, and display is reassembled and synchronized when the Echo plays. This means the server should have fast data transfer ("fast disks") and a generous amount of CPU, but little RAM or network bandwidth.

It requires, by contrast, a fast network: the data (video, audio, display) must travel to multiple student computers and appear perfectly synchronized. It requires a high-bandwidth network with large amounts of RAM.
