Descrição

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.
