The newest intelligence in IoT gateway

Industrial communication systems primarily consist of legacy systems such as CAN and Modbus– well-working and established industry-specific networks installed in millions of systems. In the last decades, there has been a push for IP-based technology which has made Ethernet become a popular network. But to meet the demands of industrial applications, it has been necessary to implement real-time functionality. This has resulted in special IP-based networks – Industrial Ethernet. These are now the fastest-growing networks in new industrial installations. Consequently, there is a vast amount of industrial systems that need to be migrated to new technologies and this change will be gradual — no company wants to change well-functioning systems overnight. Migration from old to new calls for gateways and middleware software to upgrade existing well-working machines and systems to take advantage of the new technologies. IIoT provides a huge opportunity to new gains in flexibility and productivity but also challenges as to how to merge existing installations to these new technologies.

Here an edge gateway provides the link between a local area network (LAN) of edge devices and a wide area network (WAN) linking to higher level services. The edge gateway may itself act as the provider of local connectivity by acting as a hub. It serves to insulate the edge devices from the WAN and can contain some data processing, analytics, control logic, and application entities. Edge gateway wants to change this by empowering the device to make decisions as soon as the data is received. Reducing the latency and ‘time to act’ significantly benefits autonomous or critical applications like the increasing swarms of drones and unmanned safety units being developed for agriculture and emergency applications like forest fires. The other benefit to processing on the edge is that it theoretically reduces the amount of data sent back over a wireless network, a device might alert someone that it is taking an action or has completed an action rather than sending a request to act, waiting for a response, then acting.
In addition to realtime topic, software portability significantly improves the development speed and cost of connected systems by enabling communications or application code to be reused on multiple platforms. Two factors have emerged that have enabled code sharing between edge and cloud platforms: compatible virtual machines (VMs) and portable operating systems.

In summary, the IoT gateway is more and more important to connect the field side industrial applications into cloud infrastructure for further optimal operation, container technology and SWARM methodology would be key point to help customer to adapt the IoT megatrend more quickly, achieve this perspective that would include the following aspects.
1. Container technology to leverage gateway application package to different operating systems.
2. SWARM technology on gateway system including optimal methodologies for heterogeneous edge gateway systems
3. A less latency method of communication between containers on local and remote systems.
