Industrial Network - Comparison of different network topology

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

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.

Industrial Network Topology - HSR-PRP
