A SIP endpoint maintains an ordered list of the controllers that are available to it and registers with a subset containing the first N controllers in the list, where N is a plurality, but not all, of the controllers in the list, and obtains services from one or more of the controllers of the subset. If one of the controllers of the subset becomes unavailable, the endpoint registers with the (N+1)st controller in the list, thereby adding it to the subset. If and when the one controller becomes available again, the endpoint de-registers with the (N+1)st controller, thereby removing it from the subset, and if necessary re-registers with one controller. The subset thus forms a sliding window on the list."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Registering an endpoint with a sliding window of controllers in a list of controllers of a survivable network","description":"Provided are methods, devices, and systems for maintaining a SIP survivable network.
