Different network topology for Industrial Network
Mesh
Feature - Every nodes connects to each other
Advantages - Highly reliable Self healing
Disadvantage - Too costly for large network deployment
STP
Feature - IEEE 802.1D Loop-free tree shape topology
Advantages - Open protocol Self healing
Disadvantages - Recovery time 1.5 sec
RSTP
Feature - IEEE 802.1w Loop free tree shape topology
Advantages - Open protocol Faster recovery time - 1sec
Disadvantages -Recovery time not fast enough
Ring/Chain
Feature - Proprietary technology Ring/Chain topology
Advantages - Low cost Self healing Faster recovery time
Disadvantages - Vendor specific topology
HSR/PRP
Feature - IEC 61850 Dual network Dual path (HSR)
Advantages - Open protocol Self healing Zero recovery time (0ms)
Disadvantages - Prohibitively expensive unless absolutely needed.
