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

Industrial Network Topology - Mesh

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

Industrial Network Topology - STP-RSTP

Ring/Chain

Feature - Proprietary technology
Ring/Chain topology

Advantages - Low cost
Self healing
Faster recovery time

Disadvantages -
Vendor specific topology

Industrial Network Topology - Ring-Chain

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.
