Advanced multi-service metropolitan networks are characterized by diverse demands and an unpredictable traffic pattern. In these networks, the transport layer must carry a variety of signals in a scalable, compact, and economical fashion to have an optimal transport network. Factors such as low initial cost, scalability, high capacity, ease of engineering, and simple operations are required to support metropolitan transport networks. The combination of the transport layer with lower-capacity service platforms at the edges results in an optimal flexible, scalable, and manageable solution for metropolitan network needs.
