Instead of doing everything "in the cloud," this is about building a layer in between the cloud and the end-user. This layer, sometimes referred to as "edge computing," is essentially a smart solution to pre-distribute information from the cloud to a local "super" edge-router with an integrated server. Let's look at an example. Someone interested in the news has a subscription that downloads all the news articles and video clips at 6 AM to her local router/server. She can browse during breakfast at 8 AM, going through the news and watching clips at incredibly high speeds and without delays. The bottleneck of getting information from the Internet has been removed. The router/server has become a traditional mailbox, in essence, and the news is kept up-to-date in her mailbox (router/server) all during the day. From the other direction, "edge computing" is also helpful. Instead of sending a complete voice command, chat, or conversation to the cloud for processing, the processing already takes place in the router, reducing the amount of data to be transmitted. It is clear that such an architecture overhaul would be a tremendous undertaking, but it may nevertheless be a cheaper solution than rewiring all the exits from the high-speed Internet freeway. Certainly cheaper for the network providers, because in this situation the consumer will pick up the tab – either by paying for the more sophisticated edge-router and/or paying for the subscription for "edge routing" services. the home the plans with IEEE 802.11ax are not reaching beyond the 4Gbps for in-building distribution—but as can be found in many installations in the home or in an office: 10-100Gbps Ethernet may come to the rescue if needed. So, What Can We Realistically Expect? In the near future, we probably have to settle with end nodes using 1Gbps IEEE 802.11ac, the home infrastructure will use 4Gbps IEEE 802.11ax, and probably with something like DOCSIS 3.1 FD at 10Gbps. This will give a balanced picture that can be the next stabilizing point for the industry for Internet access at home and in buildings. In this scenario, all the resources are effectively balanced and put in a proper hierarchy. Cloud vs. Edge Interestingly, there is another solution for the broken hierarchy. But it would not be a simple one. The Practical Next Step?
