Near to the information source, rather than transmitted to the data center or long path through the cloud. According to DC forecast that there will be more than 50% of data processing at the edge: by 2020, will account for 189% of the total expenditure of Things infrastructure expenditure edge of the 29 meter Currently, a large number of industrial applications of Internet technology has been the scene of edge put forward a clear demand, and has begun to drop. Application of the platform, the edge device collects data (typically a large number of mutual data generated by the equipment). Computing edge data in the local classified, so some data can be processed locally, thus reducing the backhaul traffic to a central repository.
After the number of the edge layer processing, it will be transmitted to a central processing or part of the data repository, such as data centers, office facilities or synergistic cloud infrastructure, reduce network infrastructure costs
Data transmission costs
(-) network transmission technology bottleneck edge technology is a key factor driving the development of the whole, distributed model challenges connectivity and network latency or bandwidth-constrained, easily lead to industrial applications Internet platform landing difficult. Computing applications primary edge is generated in the network transmission scenario, creating demand for intelligent edge. Internet platform for industrial applications wired and wireless internet access, in accordance with the needs of transmission and strong, present, China's enterprise network infrastructure industry overall level is not high, in many cases, network transmission limitations often become the bottleneck of the application platform landing. Given these advantages count edge technology, it is necessary to deploy intelligent edge for these scenarios stations and programs.
