The hierarchical network topology comprises at least a first level and an endpoint level. The feature server queries a communication device at the first level to determine if the communication device at the first level is reachable via one or more routes. In response to determining that the communication device at the first level is not reachable via any of the one or more routes, the feature server forbears from querying one or more communication endpoints associated with the communication device at the first level for the presence information. In response to determining that the communication device at the first level is now reachable via the one or more routes, the feature server queries the one or more communication endpoints associated with the communication device at the first level for the presence information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method to prevent polling overload for detection of presence information","description":"A feature server determines a hierarchical network topology for identifying presence information of communication endpoints.
