The time-sensitive networking is defined by 11 IEEE standards that are collectively called as IEEE 802.1. There are 8 different levels used to define Ethernet. It is important to keep it clear that TSN is not one single standard, but rather a blend of different standards all involving the industrial Ethernet.
Concepts Of Time-Sensitive Networking:
The key concepts that actually define what Time-Sensitive networking is as far as automation is concerned are described in detail. The first concept is the one that relates to synchronization that is derived from IEEE 802.1AS.
The time-sensitive networking enables one to make sure that all the devices on a network all have the same time. Basically, each device on the network knows what the time is and they all synchronize together, and the network flows in an organized way and makes sure everything is synchronized from one station to another.
The Precision Time Protocol derived from another standard that is IEEE 1588 helps you control latency across the network because there is no variation in time and thus everything is synchronized together and everything works together in a predictable way.
The other key concept of Time-sensitive networking is real-time scheduling with which we can prioritize traffic on the network by assigning different time slots and different priority levels to traffic on the network depending on the kind of traffic. The Time Aware Shaper helps control the latency and jitter. This makes sure there is no variation in time and everything works in a deterministic way.
Importance Of TSN Technology For Automation:
The TSN offers many benefits for the Ethernet compared to today’s Ethernet and this is why the TSN technology has gained so much importance. The TSN allows one to mix together traffic that maybe even different network protocols. Since we can prioritize traffic types, all of this can be done without slowing down the network and thus the negative impact on the performance can be prevented.
Thereby we can promote more traffic on the network. Maximization of the bandwidth utilization can be achieved because of the prioritization of traffic on the network. Also, there is a great potential to even combine different kinds of industrial Ethernet all together on one physical network. Thus lowered TCO is achieved where one can do more with less network infrastructure. TSN technology has the potential to deliver secure and reliable communication for the future.
