Abstract: A Managed Site (10), a logical network entity, is composed of a number of Sub Sites (20) in a one to many relationship. A Sub Site (20) is a logical component, which is composed of a number of Engines (30). Nodes (40) similarly relates to their Engine (30) in a many to one relationship. A Node (40) is a collection of Managed Elements (ME's) (50) (while being an ME (50) itself), which represent network state information. The subsite (20) consists of the engine (30) connected to server nodes (40). One or more clients (110) are connected to the management engine (30) and access management engine (30) information relating to managed elements (50) including nodes (40). The connected manager engines may communicate with one another so that, for example, in the event of a failure, one of the manager engines remaining on line commences monitoring of manage elements assigned to the failed manager engine.
