Physical layer impairment aware routing (PLIAR) in WDM optical networks: issues and challenges
TL;DR: The purpose of this article is to provide a comprehensive survey of various PLIs, their effects, and the available modeling and mitigation techniques and identify several important research issues that need to be addressed to realize dynamically reconfigurable next-generation optical networks.
Journal ArticleDOI

TL;DR: In this paper, an impairment aware network planning and operation tool (NPOT) is proposed to consider the impact of physical layer impairments in the planning of all-optical (and translucent) networks.
Journal ArticleDOI
Differentiated QoS for survivable WDM optical networks
TL;DR: A survey of various methods that have been proposed for providing service differentiation in survivable WDM networks and discuss their performance is presented.
Proceedings ArticleDOI
Routing differentiated reliable connections in single- and multifiber WDM optical networks
TL;DR: This paper develops an efficient algorithm to select routes and wavelengths to establish an R-connection with a specified reliability guarantee, in a resource efficient manner, using primary-backup approach and presents the initial experimental results which suggest that the scheme is attractive enough in terms of resource utilization and average call acceptance ratio.
