abstract
As networks increase in size, heterogeneity, complexity and pervasiveness, effective
management of such networks becomes more important and increasingly difficult. In this
context, PBNM (Policy-Based Network Management) has been gaining popularity in the
recent years. New demands on internetworking, services specification, QoS and
generically on network management functionality have been driving users to consider
this paradigm in their own networks.
As people start exploiting PBNM, another aspect comes to attention: transactional
integrity. Transactional control envisages achieving consistent state changes along the
network. In other words, state transition in network devices is only authorized if all the
related operations are successfully taken.
In this paper we propose a transactional control mechanism for PBNM systems,
namely its assurance across different systems and different network domains.
