Carrier Ethernet

Utilizing Ethernet Ring Protection Switching and Ethernet Private Line utility companies can provide more service options to their customers, especially in remote areas.

Why Carrier Ethernet

Slow recovery time and network delays are not an option in critical communications. Networks must be reliable, scalable, and avoid delay. Carrier Ethernet provides a scalable solution with quick fault recovery and stable communications.

Features & Technology

Ethernet Ring Protection Switching (ERPS)

As many networks move toward carrier Ethernet and replace SONET/SDH networks, ring recovery and interoperability between brands are growing concern. One main concern is preventing a broadcast storm while minor differences between devices result in less resiliency and longer training and setup times.

As an effort to resolve this issue, ITU-T (International Telecommunication Unit) created Ethernet Ring Protection Switching (ERPS) under G.8032 Recommendation. ERPS helps achieve high reliability and network stability by providing sub-50ms protection and recovery switching for Ethernet networks in a ring topology. Loop avoidance is done by designating one ring node as responsible for blocking traffic. When a link fails, the designated node unblocks allowing traffic to continue.

The G.8032 standard protocol allows users to have different brands while ensuring network reliability and resiliency. G.8032v1 supported a single Ethernet ring while G.8032v2 added more features including support for multiple rings/ladder network.

E-Line: Ethernet Virtual Private Line

Ethernet Private Line (EPL) or Ethernet Virtual Private Line (EVPL) provides dedicated bandwidth between two points. Using an Ethernet virtual connection (EVC) between a pair of dedicated user-network interfaces (UNIs), E-line replaces traditional private line services and offers more bandwidth at a lower cost.

EVPL allows users to instantly and securely communicate between two UNIs. This private connection heightens network efficiency providing stable, secure, and efficient data transmission.
