Carrier Ethernet technology provides carriers with end-to-end Ethernet services over wide area networks (WANs), and implements both cost and simplicity benefits. However, Ethernet doesn’t have the same carrier-grade functionality of the TDM networks they aim to replace, resulting in challenges associated with quality of service (QoS) guarantees, rapid failover implementation, service management, and scalability. New standards and objectives address these issues, allowing carriers to effectively and reliably deploy Ethernet-based carrier networks. Read more »
