All of the network nodes inside an HSR ring must be HSR-capable. HSR-unaware nodes can be attached to the HSR
ring through the use of a RedBox (Redundancy Box). Compared to PRP, HSR only demands approximately half of
the network infrastructure. However, network bandwidth on an HSR ring is approximately halved compared with a
network ring based on RSTP technology.
NOTE
Current HSR implementation limits link utilization to 74% when using multicast traffic.
