eRSTP™ (enhanced Rapid Spanning Tree Protocol)

Enjoy an enhanced performance with eRSTP protocol from Siemens
This eRSTP protocol offers improved fault recovery times and performance for large ring network topologies compared to earlier protocols.
A protocol for preventing “broadcast storms”
Evolving out of previous STP and RSTP standards, eRSTP prevents “broadcast storms” – where a single broadcast frame is circulated endlessly by switches on a loop in a network, thus consuming all available bandwidth and making the network unusable.
