CORBA has no notion of hierarchy but assumes symmetric peer-to-peer
relationships between objects; in terms of management, this
results in an extension of the role model: Not only are manager/agent or
manager/manager relationships possible, but also agent/agent
relationships. This simplifies the distribution and delegation of
management functionality and supports cooperation between different
components of the management infrastructure. It is therefore not only
possible to delegate functionality from managing systems to managed
systems but also between managed systems.
Another point is that the
roles of systems participating in management activities are subject to
dynamic changes: roles like "managing system" and "managed system" are
temporary and bound to the tasks to be done. This has major implications on security (see 3.2.2).
