High Availability

High Availability

Availability = MTTF / (MTTF+MTTR) Mean-Time-To-Fail (MTTF) Mean-Time-To-Repair (MTTR)

High Availability


High Availability

Availability = MTTF / (MTTF+MTTR) Mean-Time-To-Fail (MTTF) Mean-Time-To-Repair (MTTR)

Impossible to create networks that never fail;

Key to High Availability is reduced recovery time

Availability is increased by introducing Redundancy

Dynamic Network Redundancy


Normal !Operation! Failure! Recovery!

Dev = Device!SW = Ethernet!

Cost Sample PRP/HSR TSN Total = 18550 27400 20050 20750 Cost Difference = 48% 9% 12% [(S-T)/S]

Performance •  FRER provides higher or equal performance to PRP/HSR

Determinism •  Higher degree of control over the determinism of the System with control of interference

traffic.
