What is Network Design

The wavelength division multiplexing passive optical network (WDM-PON) is a natural path forward to satisfy demands of optical network operators to develop valuable converged optical metropolitan and access networks. For effective utilization of possible transmission capacities, available wavelengths must be carefully designed for their utilization. Therefore, some principles of wavelength allocation and scheduling methods are characterized and specified. For ensuring the network reliability, efficient traffic protection mechanisms must be implemented. Simultaneously, different equipment in remote nodes can be installed. Therefore, different WDM-PON network designs with traffic protection securing are analyzed and compared. Protection possibilities for various network parts and elements are characterized and optical power budgets are evaluated and optimized. Finally, a research of the DWA algorithms can be realized using functionalities of selected wavelength scheduling methods. Moreover, the wavelength transmission capacity characterizing can be simultaneously determined.
