You originally designed your network to connect workstations and for data communications.
Next came VoIP, which changed some of the network characteristics by demands to reduce delay and jitter, and then video, with higher bandwidth requirements and streaming.
Most IoT endpoints comprise sensors, processors, network software, and applications from disparate vendors.
Endpoints are designed to deliver specific functions, and they produce distinct types of traffic.
Therefore, no single network design will support all the various endpoints.
The traffic created by IoT devices varies considerably.
Dumb devices require more interaction over the network with the data center or cloud service.
Sensor data from passive devices
When IP networks transfer data, delays of hundreds of milliseconds is acceptable.
Delay tolerance for IoT depends on the application.
With edge processing, a gateway at the network edge can help reduce delay and bandwidth demands on the network.
The demands on the network will be far more varied than what IP network designers have encountered in the past, including for voice and video over IP.
One of the benefits expected with 5G networks is the ability to deliver very low delay for IoT.
IoT devices that can work with longer delays may be better suited for wired connections.
The network designer may want to influence the gateway design by requesting that more work be performed at the edge.
Five-nines availability becomes a high priority in the network design.
The use of the IoT endpoints further integrates the network into the success or failure of the organization.
Deploying gateways can offer sensor support even when the network connection fails.
Voice and video traffic is usually given higher priority than data traffic.
Some IoT devices may demand priority transfers that will need higher QoS than voice and video.
SD-WAN and MPLS may be required for some of the IoT traffic, while more tolerant IoT traffic may be transferred with lower priorities
