5 Conclusion
Ethernet evolved from LAN into Metro areas covering speeds from 10 Mbps up to 10 Gbps and the next generation Ethernet speed of 100Gbps will be the enabler of Ethernet-based pure packet core networks. Carriergradeness of Ethernet-based packet architectures is the major point. A careful analysis of the required protocol features like network resilience, QoS, and OAM shows many redundancies within the layers of today’s network architectures that have to be resolved shaping a new end-to-end Ethernet layer with the required scalability.
A CAPEX and OPEX analysis demonstrates a considerable cost advantage of 100G-Ethernet in comparison to SDH-based solutions. The superior CAPEX performance results from a huge cost advantage of Ethernet devices and their fast price decline. The reduced switch and line card count in 100G-Ethernet networks and the efficient economics of Ethernet services are responsible for a superior OPEX performance.
Therefore, it can be said that Ethernet has a promising future in core networks, not just as link technology supporting an upper routing layer, but as a complete, cost-effective, and service-oriented infrastructure layer in the area of core networks. The industry-wide efforts to cover remaining challenges also confirm this outlook.
