    • A feature server determines a hierarchical network topology for identifying presence information of communication endpoints. 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.
    • 特征服务器确定用于识别通信端点的存在信息的分层网络拓扑。 分级网络拓扑包括至少第一级和端点级。 特征服务器查询第一级的通信设备,以确定第一级的通信设备是否可通过一条或多条路由到达。 响应于确定通过所述一个或多个路由中的任何一个无法到达所述第一级的所述通信设备,所述特征服务器禁止在所述第一级别查询与所述通信设备相关联的一个或多个通信端点以存在所述存在信息。 响应于确定第一级别的通信设备现在可以经由一条或多条路线到达,特征服务器在第一级别查询与通信设备相关联的一个或多个通信端点用于存在信息。
