5.5 ERPS
In any industrial automation application, designing redundant ring network paths to protect networks
from unexpected failovers is extremely important in mission-critical networks because they need to
provide uninterrupted services. In practice, several loop protection methods are implemented to
ensure that network functions normally without loops and recovers as soon as possible when a
point of failure occurs. The most popular ones are RSTP (802.1w) and MSTP (802.1s). For
industrial applications, the ERPS (G.8032) is highly recommended since they can achieve faster
recovery time than any STP protocol.
Due to different manufacturers who provide their own proprietary redundant ring protocol, and users
facing inconvenient situations with compatibility issues when they are planning to design or upgrade
their ring network for future proof, Antaira is proud to introduce and implement Ethernet Ring
Protection Switching (ERPS) protocol as a standard ring solution for network redundancy with all
new industrial managed Ethernet switches. In order to provide users with the flexibility and
compatibility when there are any existing switches that contains the standard ERPS protocol.
