This technical white paper contrasts several
approaches to delivering Ethernet services in metropolitan area
networks. Resilient Packet Ring (RPR) is the most scalable and
cost-effective architecture for the delivery of carrier-class
Ethernet and other packet services on metropolitan fiber rings. RPR
networks will play an important role in the evolution of the public
network, providing a reliable, scalable and efficient packet edge
for the emerging optical Internet.
