WebJul 7, 2011 · The Rapid Spanning Tree Protocol (RSTP) generally replaced STP. This is an improved version of STP and was defined from IEEE 802.1 group in 1998. RSTP … WebHSR. HSR is a redundancy protocol, just like PRP. It ensures high availability and reduces the network recovery time and therefore the transmission time to “zero”. In this case, the network has a ring topology, and when node A wants to send a message to node B, it duplicates it and sends it in both directions of the ring.
