Enhance your understanding of robust optical network design with “Survivable Optical WDM Networks” by The Bookish Owl. This essential resource explores critical strategies for creating and managing WDM networks that maximize connection capacity and ensure rapid recovery from failures. Delve into various network architectures, including wavelength-routed WDM, sub-wavelength grooming, and SONET/SDH over WDM. The book meticulously examines protection schemes at different granularities (wavelength, sub-wavelength) and protection entities (path, sub-path, segment), offering insights into single-path and multi-path routing. Discover the crucial tradeoffs between resource efficiency and recovery time, with practical approaches and analysis designed to improve revenue and service quality for modern optical networks.
