The most vital factor in a well-designed network, even more so than network speed, is network stability and the ability to recover from connection failure. ERPS (Ethernet Ring Protection Switching) under the ITU-T G.8032 standard is a protocol that provides an efficient wide-area multipoint connectivity in a ring topology network. Ultimately, ERPS offers excellent network stability and seamless connectivity in a world that’s constantly streaming data. Additional benefits include:
- Faster recovery time than STP/RSTP/MSTP.
- Reduces service costs
- Improved customer satisfaction with guaranteed service up-time
- Ideal for mission-critical applications
