Internet of Things (IoT): WinterGreen Research study: Market Shares, Strategies, and Forecasts, Worldwide, 2017-2023.  The study addressesThe Internet of Things (IoT) is the next Industrial Revolution.  It will impact the way all businesses, governments, and consumers interact with the physical world.  Providers of Industrial IoT aim to implement asset efficiency solutions.  Designing the asset efficiency solution, developing the application, adapting advanced engineering knowledge for the use cases, and supplying the information platform is the composite task of the analytics engine.  IBM is a premier supplier of an analytics engine with its Watson product.  

1 Gbps and 10 Gbps speed has been used in data centers for years.  The jump to 40 Gbps and 100 Gbps has come rapidly as a result of the need to increase the quantity of data managed inside the data center with more analytics and more applications.  Many of the Cloud 2.0 mega data centers have moved to 100 Gbps, presaging the move to 400 Gbps.
One reason for the increase in speed is the growth of data consumption, attributed to smartphones, social media, video streaming, Internet of Things (IoT), and big data.   Big pipes are used to cope with the huge quantities of data that are being transferred.
