Routing and Wavelength Assignment for DWDM-Centric Metro Aggregation Network

Dense-wavelength-division multiplexing (DWDM)-centric metro/aggregation networking is defined as predominantly using packet aggregation at the edges of the aggregation domain, while using DWDM at the center of the network.

In this study, a DWDM-centric architecture is proposed and its planning problem is solved by algorithms based on intelligent wavelength assignment (WA) and an auxiliary-graph approach exploiting load- balanced routing and the optical-multiplexing capability of wavelength selective switches (WSSes).
