To provide failure-safe connections in optical net-  works, lightpaths can be protected. Protected lightpaths consist of a primary  path and a backup path which are disjoint and ensure connection continuity  in case of a single link failure. Optical networks consist of at least two layers,  the optical layer and the physical layer. And although the primary and backup  paths are disjoint in the optical layer, in the physical layer they may share the  same fiber span or duct. These links are in the same Shared Risk Link Group  (SRLG). If one link of a SRLG fails then all fail. Because of this, a single fail-  ure at the physical layer can causes multiple failures at the optical layer and  protected paths could get disconnected if both paths have fibers in the broken  fiber span. This work proposes an exact algorithm which finds the shortest  SRLG-disjoint protected path in a network through an iterative approach.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659379178\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659379178","offer_id":39484198355037,"sku":"9783659379178","price":35.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c2e21362-a880-4218-b323-fa7a96a4f996.jpg?v=1773726776","url":"https:\/\/shop.autorenwelt.de\/products\/diverse-routing-in-srlg-networks-von-rob-juffermans","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
