Multichannel Optical Networks: Theory and Practice
This paper considers optical networks which employ w avelength-routing switches that e n able the e stablishment o f w avelength-division-multiplexed (WDM) channels, called lightpaths, between node-pairs. In such n etworks, the failure of a single link may cause the failure of several optical channels. Given a set of lightpaths, that m ay comprise of a virtual topology, a n d xed alternate r o u ting t ables at each node, this paper examines the f o l l o wing problem: how t o a l l o c a tedoi:10.1090/dimacs/046/10 dblp:conf/dimacs/RamamurthyM98 fatcat:zeukd6hdjzd63lpixmwu6hluyq
