This new approach obtains all secondary routes assigned to each possible connection (user). The secondary routes replace the main routes when these are affected by at least one fault, which keeps the users connected as long as, for each connection, there is at least one route with operative links for reaching the destination nodes thereof. This new approach solves the general case of an arbitrary set of simultaneous link failures. The method also assesses the number of wavelengths  for each link  of the network, so that the probability of any connection request from a determined user c being blocked is less than a predefined threshold βc, despite the possible occurrence of the fault scenario."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fault tolerance method for any set of simultaneous link faults in dynamic WDM optical networks with wavelength continuity constraint","description":"The present invention proposes a new method for solving the problem of fault tolerance.
