Abstract

A method is disclosed for managing a network entity that is initiated by the network entity, the method comprising the computer-implemented steps performed at the network entity of monitoring the network entity; periodically evaluating one or more specified conditions at the managed network entity; when one or more of the specified conditions are satisfied, then gathering specified information from the managed network entity, preparing a message that includes the specified information and the specified conditions that were satisfied, and sending the message to a management point.

storing said management request in the management proxy while awaiting a poll for the management request from the network entity;

receiving a poll message from the network entity, said poll message requesting from the management proxy any available management requests applicable to the network entity;

in response to the poll message;

selecting one or more management requests stored in the management proxy that match the network entity; and

delivering the selected one or more management requests to the network entity;

wherein the management proxy is external to the management application and the network entity;

wherein the method is performed by one or more computing devices.

2. A method comprising the computer-implemented steps of:
