The entropy table maps the egress router to one or more available paths to the egress router, and associated entropy information for each respective available path of the one or more available paths. The ingress router may then forward traffic to the egress router using the entropy table to load share the traffic across the one or more available paths using the associated entropy information for each respective available path. In response to detecting a failure of a particular path of the one or more available paths, however, the ingress router then removes the particular path from the entropy table, thereby ceasing forwarding of traffic over the particular path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reliable multipath forwarding for encapsulation protocols","description":"In one embodiment, an ingress router sends a multipath information query across a computer network toward an egress router, and builds an entropy table based on received query responses.
