Where will the boxes go? Who will buy? Dozens of companies are jumping in, many with wild and contradictory ideas. "Levels of Edge" brings some order to the analysis.
Edge clouds reduce latency with servers close to the customer. The true believers talk 1-4 ms; the actual results for now are likely 15-25 ms. That's great for multi-player Pokemon, worthless for controlling autonomous vehicles.
Level 1 Edge Clouds don't exist yet and may cost too much to deploy. 1 ms 5G is still in the lab and years away from deployment. the 5G deploying is ~10 ms.
A Level 2 site is building in Chicago with equipment moving in. Vapor is supplying the main boxes. The server adds ~ 4 ms. Level 2 sites aim for 10-20 ms. Cole Crawford of Vapor tells Mike Dano their boxes are "tower-aggregated and connected, not tower-located." Vapor is not, as originally thought, going directly to the cell. Federated Wireless is testing a new radio network, which may be the only way to performance desired.
Level 3 sites are testing in live networks at Deutsche Telekom and in China.
Level 3 is still within the carrier network but further back. Current expectations are 20-25 seconds, with better to come.
Level 4 sites are an intriguing new possibility. Verizon and Telefonica are installing routers and switches with very low latency and cutting out layers. In 25-50 ms, networks like this can carry your data to the peering points at the other end of their networks. 9 locations can cover most of Germany. The telcos can build major datacenters there. Akamai and the Googles of the world are already there. The faster transport networks could reduce the need for Edge Clouds.
Level 5 is what we have today. My Netflix and everything else runs fine. Maybe that's enough.
Improvements welcome. It's an early draft.
