The local computation engine and the link state protocol support automatic establishment of redundant paths and cautious restoration in a packet network. The method includes receiving an explicit path (EP) type length value (TLV) via a link state routing protocol, executing a shortest path algorithm to obtain a shortest path for loose hops of a path identified by the EP TLV, the shortest path to be a primary path, updating a network graph to prune links of the primary path or bias links of the primary path, and calculating a backup path using the shortest path algorithm on the updated network graph."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automatic establishment of redundant paths with cautious restoration in a packet network","description":"A method is implemented by a network device executing a local computation engine and a link state routing protocol.
