RAD unveils resilient fast Ethernet ring technology

HONGKONG -- RAD Data Technology has developed a new technology incorporated in its Megaplex data/voice multiplexer that provides self-healing capabilities on 100Mbps fast Ethernet fiber. RAD's unique, resilient fast Ethernet ring (RFER) carrier-class technology can reroute traffic within 50ms in case of link failure on any segment of the ring. This enables enterprises, campuses, power firms, transportation firms and utilities to create a highly reliable network.

RFER uses VLANs to overcome the storming problems that occur when attempting to broadcast over Ethernet rings or when a packet is assigned an incorrect address. RFER is implemented in the new ML-IP module for RAD's popular Megaplex family of modular integrated access multiplexers (IAMs). The ML-IP is an Ethernet uplink module with upto 8Mbps uplink capacity that can be ordered with either 10/100BaseT or 100Base Fx interfaces with 50ms protection, and serves as the main link to the IP network. The Megaplex-based network can support upto 40 EI lines in a ring. RFER allows a total separation between rings, ensuring that a failure in one particular point will not bring down the entire network.

This application has been tested and certified for service resilience and voice quality by the Berlin-based European Advanced Networking Test Center (EANTC). The Megaplex platform is a perfect addition to underpopulated next-generation networks, allowing the transmission of all legacy services over IP. The Megaplex is standard compliant, ensuring compatibility in multivendor environments worldwide.
