To overcome some of these challenges, we built our own Java-based player, complete with caching, content compression, and even bandwidth detection so it could switch between video, audio, and text versions of a course depending on network speed. Ultimately the business didn’t survive the dotcom bust, but it lit a spark.

High-speed networks through 5G may represent the next generation of cord cutting. Those waits can be significant, even if you’re on a corporate network. Let’s get back to home networking.

One of the big topics at the OpenStack conference was how to prepare and implement a successful transition to 5G. If I am wearing a VR headset and turn my head, the network has to send the information for what to display before I would see it. This requires 1 ms network latency. These have to communicate with each other.
