With the rapid development and application of the Internet of Things, big data, artificial intelligence, and other technologies, the traditional cloud computing model has brought great challenges, which has also given birth to the transformation of computing mode, edge computing was born.

Figure 1 The evolution of edge computing

The so-called edge computing, refers to the nearest end of the service, using the network, computing, storage, application core capabilities as one of the open platform, near the source of the object or data. In layman's terms, it is after the calculation and processing of data is done locally in data collection (e.g. time stamping, data formatting, classification of event and process data), "in-place" decision-making based on the results, and the processing of completed data for storage, forwarding cloud platform and other operations.

Edge computing offers the following advantages over cloud computing:

Security: the original data processing locally solves the risk of data loss or information leakage, which solves the risk that the path of private data transmission to the data center is long.

Low latency: Edge gateways make "in-place" decisions based on preset business logic, eliminating bidirectional transmission delays for terminals and cloud centers.

High reliability: No longer relying on central servers, each edge gateway is an edge server, distributed deployment, to avoid the central server due to the collapse of large-scale downtime, downtime.

As the carrier of edge computing services, edge computing gateway plays an important role, whether it is the sensor interface, the diversity of networking support, or CPU computing power, all affect the ability of edge computing. Especially in the context of the industrial Internet, IT and OT convergence is also an important capability for edge gateways, FET1028A-C has six TSN-enabled Gigabit Ethernet interfaces, and a built-in TSN-enabled 4-port Switch, to meet the convergence of IT and OT networks in industrial sites.
